The 3-valve setup is based on using a valve on each of the side ports as shown below. You also add a dip tube inside the left port. This allows the wort to be pumped out from the lower port, through the counterflow chiller and back into the left side port through the valve.

With this setup you can take advantage of a whirlpool during cooling. Proteins and hops will form a cone in the middle of the tank thus decreasing your losses to trub. We also recommend circulating outside the malt pipe during mashing to improve temperature stability. By using the bottom 3-way valve in a middle position, you can split the flow around the malt pipe and over the grain bed. We recommend running the pump on 80-100% power and circulating both ways at the same time. More on this is found in the user manual.

You also add an extra 3-way valve on the lower port. This makes you able to also clean the system without disconnecting any tubes. As an option you can use the third valve to bypass the cooler.

Tri Clamp (TC) connectors offers both fast and leak-free connections. TC connectors is the preferred system in the food and beverage industry because it offers a sanitary connection which is easy to clean.

The Brewtools products uses as much of these connectors and fittings as possbile as it offers increased flexibility and is easy to use. The Pro Series brewing systems mainly use 34mm TC connectors. They have a 34mm outside diameter and you use 34mm Tri Clamps to hold two connectors together with a gasket between them. All our gaskets are food grade silicone.

We also use other sizes TC connectors. The Steam hats use a 4" TC flange on the top, and the Steam Condenser mainly uses 2" TC connectors.

Here is a list of the most frequent used TC sizes

FCS is a modular control system designed, developed and manufactured by Brewtools in Norway.

The vision behind the system is to take industrial technology and make that available for microbreweries and homebrewers. Using the latest electronic component technology and clever software engineering, we are able to make features that used to be very expensive and complicated available for everyone.

The Brewing Systems ships standard with one 3-way valve. This will normally be placed on the right side of the system, but if you don't want to sparge using the internal pump, you can install it on the left side to enable whirlpooling. Remember to get an extra dip tube if you want to use this option

By adding more valves, the flexibility will increase, and you can partly or completely avoid having to disconnect tubing or pipes during your brewday. What setup is the best, is subjective. A general advice is to start with the 2-valve starter pack and expand as you get more experience.

When a new version is available, your system will automatically download the update and let you know when it's ready to install. The Micro-SD card must be installed in the system as temporary storage for OTA updates The system ships with the MicroSD card pre-installed.

Update options

From version V01.07.01 it is possible to select Standard or Beta updates. If beta is chosen, you will get access to the very latest version with an increased risk of minor bugs. This option is suitable for those who want access to the latest functions and would like to help contribute with feedback so that we can make the software even better.

Our overflow pipe is an accessory kit that will assist in limiting the risk of exposing the heating elements in an event of stuck mash or too much flow over the grain bed. The principle is simple. If the flow up the center pipe and over the grain bed is greater than what naturally drains through the grain bed, the liquid level will increase and drain through the overflow pipe and end up in the bottom of the tank. This way it is more unlikely that the malt pipe will overflow and end up exposing the heating elements.

The overflow pipe kit is designed with three different length of telescopic pipes and will fit both B40pro, B80pro and B150pro.

The sensor does not make a sound. Is it broken?

Check that the sensor is connected and shown on the settings page listing all sensors. The sensor makes sound when measuring, but the sensor is not continuously measuring, only short periods of up to 5 minutes every hour or so.

Can the sensor be updated?

The Pro Series Brewing Systems are designed for maximum flexibility. There are many ways of using the systems based on personal preference, what kind of accessories you have and how your brewing area is set up. Below, we will explain the principles of the system and some of the possibilites it gives you.

The tank and malt pipe are built from SS304 stainless steel with a thickness of 1.0/1.2mm. All outlets and ports on the tanks and valves are Tri-Clamp for maximum flexibility. The flanges and steel parts are cast in SS304 stainless steel, and CNC machined. The pump features a 24V brushless motor. It's quiet and powerful and the speed is controlled from the touch-screen. All tubes are 16x25mm food grade high quality silicone with high transparency. The entire system is designed and built to withstand years of use.

The basic principle in the system is a tank with a conical bottom with heating elements, a temperature sensor, a center pipe that's easily removable, an outlet port on each side and a 3-way valve in the bottom which makes it possible to circulate both over the grain bed and through the lower outlet and counterflow cooler or tube at the same time with full flow control. This makes it easy to maintain accurate temperatures outside the malt pipe as you circulate the wort around and up through the malt pipe and over the grain bed. The standard dip-tubes has two o-rings that makes them easy to adjust to the desired angle. If you brew with a lot of hops, you can adjust the dip-tube accordingly to prevent too much hops in the circulation and into the fermenter.

The right 3-way valve is used to choose the input for the pump. You can pump from the inlet dip-tube or from a second tank, usually for sparge water. In the standard setup without extra 3-way valves, this valve is also used to pump the wort to the fermenter.

This page is made to support users in understanding the different controller unit installed in glycol chillers sold by Brewtools.

The 4-valve setup is based on using a valve on each of the side ports as shown below. You also add a dip tube inside the left port. This allows the wort to be pumped out from the lower port, through the counterflow chiller and back into the left side port through the valve.

With this setup you can take advantage of a whirlpool during cooling. Proteins and hops will form a cone in the middle of the tank thus decreasing your losses to trub. We also recommend circulating outside the malt pipe during mashing to improve temperature stability. By using the bottom 3-way valve in a middle position, you can split the flow around the malt pipe and over the grain bed. We recommend running the pump on 80-100% power and circulating both ways at the same time. More on this is found in the user manual.

You also add two extra 3-way valve on the lower port. This makes you able to also clean the system without disconnecting any tubes. You can also bypass the cooler without disconnecting any tubes.

With 4 valves there are also a lot of other possible setups depending on your need.

Introduction

All our steel products are made from high-quality grade 304 stainless steel. Proper maintenance is essential; however, the required care will depend on the type of surface treatment applied during production. Our products come in three surface finishes: polished, electropolished, or our proprietary PureBlast™ finish.

Products with electropolished or PureBlast™ surfaces do not require passivation, unlike polished surfaces, which do.

Stainless steel naturally gains its corrosion resistance when the chromium content in the steel reacts with oxygen, forming a protective oxide layer on the surface. This oxidation process occurs gradually when exposed to air.

However, the process can be accelerated within 15–30 minutes through passivation. You can learn more about passivating stainless steel in the section below.

Electropolishing

An increasing number of our smaller products now undergo electropolishing as part of the final manufacturing process. Electropolishing is an electrochemical process in which the product is submerged in an acid bath. Electrical wires are attached to the steel component, turning it into an anode. As electrical current flows from the product (anode) through the electrolyte (acid bath) to the cathode, a controlled material removal takes place.

The process, which typically lasts between 2 and 20 minutes, effectively eliminates contaminants and opens micro-pores that are invisible to the naked eye. During electropolishing, a very thin layer of the steel surface (20–40 μm) is removed.

As a result, the product becomes easier to clean, the risk of hidden contaminants is significantly reduced, and no additional passivation is required.

How to passivate?

Use Citric Acid or StarSan (phosphoric acid).

We recommend passivating the steel before first-time use and 1-2 times a year. Use StarSan or similar acid-based chemicals. Fill the tank with lukewarm water. Use approximately 5ml StarSan per liter and leave it for 15-20 minutes.

The Trubinator is a device that is placed at the bottom of the brewing system at the end of the boil process. When cooling starts, a whirlpool is generated. This makes the hops and proteins (trub) draw towards the center. When the cooling is finished and the wort is transferred to the fermenter, the whirlpool will slow down and the trub collected inside the Trubinator.

The Trubinator has a silicone part at the bottom that protects the bottom of the kettle as well as forming a seal to keep the trub inside. The silicone part has a built in guide to help center it in the kettle.

The filter is made from expanded metal in R2x5 size. One single M6 bolt with a wingnut holds it all in place and makes the cleaning quick and simple.

The Trubinator comes in three different sizes. The diameters are identical to the malt pipes of the brewing systems. Small has the same size as B40pro malt pipe, Medium as B80pro, and Large as B150pro. You can use a smaller model than your brewing system malt pipe size if you don't brew hop-heave beers.

Sizes and capacity

• S (Small) (Ø320) - (7.2 liter)

• M (Medium) (Ø420) - (12.4 liter)

• L (Large) (Ø500) - (17.6 liter)

Product specifications

• Height: 90mm

• Material: SS304

• Surface teatment: Electropolished

Did you know that caustic cleaners will chemically react with CO2?

Sodium hydroxide (NaOH) + CO2 = Sodium Bicarbonate (NaHCO3)

If this chemical reaction happens in a closed tank, pressure will drop and potentially become vacuum which can result in a tank implosion. The video below demonstrates this in a very easy way.

So, why is this important and what can I do to prevent this from happening?

A Unitank or a Brite tank contains huge amounts of CO2 after it has been emptied. A natural next step would be to add a caustic based cleaner as example PBW and water through the top 4" opening and mount the CIP. Remember that CO2 is heavier than air and will during this process remain in the tank. Now the tank is sealed off with a chemical reaction inside. In this case having the valve on the blow-off tube open will prevent vacuum as air will move freely into the tank as the pressure drops.

Introduction

A lot of brewers (both homebrewers and professionals) use brewing software as a tool to calculate recipes. Brewing software in general is a great help prior to, during and after a brewing session. If you do not use softweare like this, here is some examples of what they can offer:

1. Inventory - Keep inventory of your malts, hops and yeast.

Brewfather integration is made available from version 1.8.2 and newer. The integration make it possible to download a recipe from Brewfather to the Brewtools control system using a 5 character code. The recipe can then be stored and edited on the Brewtools control system.

Current integration does not have ability to send live brewing status back to Brewfather. However as part of a bigger ongoing Brewtools cloud intergation process this will likely be available in the near future.

Getting started

This section explain how to use the Brewfathe integration.

As an extra safety for our customers we offer an international 5 year warranty on our products.

It's important to us that our products reflects quality and durability. We work hard to design and manufacture products that are sustainable, and that components can be replaced without discarding the whole product.

Warranty Terms

All Brewtools products are sold with a 5 year warranty assuming normal use and maintenance as described in the products user manual. Components that are especially vulnerable to incorrect use are subject to case-by-case evaluation. This mainly applies to pumps and heating elements, as they are not made to be used without liquids. Other cases where user error clearly is the cause to faults or damage is not covered by the warranty.

Our steam condenser fits our steam hats and uses cold water to cool the steam until it becomes a liquid that runs out of the condenser to a bucket or directly to the drain. It is an excellent alternative to a ventilation system.

Assembly

Assemble all parts together according to picture below. All TC connections need a gasket. The nozzle is screwed inside the top 2" to 34mm adapter.

Assemble your water supply parts to the top inlet in order to supply the unit with cold water (sold separately). Remember to use a garden hose or similar that can withstand the normal tap water pressure. Recommended fittings are either a TC34mm to garden connector or a TC34mm to hose barb. Remember to use a hose clamp.

There are a few different thread types out there. They are not necessarily interchangeable, and some uses two different names.

The most common thread standards are:

• BSP - British Standard Pipe

• NPT - National Pipe Thread

What is included as standard?

Check out from the user manual for details on what is included and what additional accessories that should be considered when buying a Unitank.

The counterflow cooler is made with high quality steel pipes, and has a design that does not reduce flow too much. The wort can be pumped throught the counterflow cooler and back into the kettle via the dip tube to create a whirlpool. The whirlpool will draw particles towards the center of the tank and reduce trub (hops and proteins) transferred to fermenter.

In use

In preparation for cooling, it is important that boiling wort is circulated through the cooler to ensure that the cooler's inner tube is sanitized.

Switch off heating elements before cooling starts. Set the bottom valve so that the liquid is pumped out and through the cooler. Follow the liquid flow to make sure that all valves are in the correct position before starting the pump. It is recommended to run the pump at full power (100%) in the beginning and slow down before the end to allow the trub to settle.

Select the return temperature display on the screen if you opted for this accessory. This way you can keep an eye on the temperature of the returning wort. Also monitor the tank temperature.

If you're doing a hop stand, the pump is stopped manually based on the tank temperature. Set the timer manually based on how long the hopstand should last, if not already set in recipe mode.

When the desired pitching temperature is reached (based on return sensor), change the flow direction after the cooler so that the wort goes to the fermenter and not back into the kettle.

Product specification

• Length: 5.2m

• Inner pipe: 14.3mm

• Outer pipe: 22mm

• Fittings: 4x TC34mm

Technical drawing

The drawing below shows more details of the counterflow cooler.

Performance test

A performance test has been carried out to demonstrate the performance of the counterflow cooler. Additionally three different ways of using the counterflow cooler has been tested to demonstrate the difference in performance.

The goal of the test is to cool 50 liters / 13.2 US gallons og boiling wort down to 20°C /68°F. The cooling water holds 9°C / 48°F and has a flow rate of 19 liter per minute / 5 US gallons per minute.

Summary

Based on the test, it becomes clear that our counterflow cooler is not designed to be used as a "single pass" method. The reason for this is due to the hugely sized 14.5mm inner diameter tube designed to minimize the flow restriction as that will negatively affect the whirlpool-function.

Method #2 is 2 minutes faster and saves 46 liters of water compared to method #1.

Introduction

This user guide explains how to disassemble and assemble the heating elements in the Brewtools ProSeries Brewing Systems.

The 2-valve setup is based on using a valve on each of the side ports as shown below. You also add a dip tube inside the left port. This allows the wort to be pumped out from the lower port, through the counterflow chiller and back into the left side port through the valve.

With this setup you can take advantage of a whirlpool during cooling. Proteins and hops will form a cone in the middle of the tank thus decreasing your losses to trub. We also recommend circulating outside the malt pipe during mashing to improve temperature stability. By using the bottom 3-way valve in a middle position, you can split the flow around the malt pipe and over the grain bed. We recommend running the pump on 80-100% power and circulating both ways at the same time.

S = Temperature sensor

Should I use an insulation jacket?

The insulation jacket will have a positive effect on your energy usage as it prevents heat loss. We recommend using the jacket if brewing outside or in a cold environment.

Can I use the standard silicone tube for tap water?

No, the standard silicone tubes are not designed to withstand the tap water pressure. Use reinforced hoses where water pressure is present. Typically that would be:

• Water into steam condenser

• Water into counterflow cooler

I don’t have 16A circuit breakers. What do I do?

The system is designed to be able to limit the average power output to allow usage on lower current circuits. Check out the section about limiting the power output in the user manual.

What is the maximum grain capacity?

The maximum grain capacity is found in the and on the product page on our website. Pushing the capacity limits will lower your mash efficiency. Our recommendation is to do your own testing to find what works best for you. We do not recommend to test maximum grain bill on your first brew.

How do I avoid «stuck mash»?

Using rice hulls and the correct crush grade is key. We recommend resting the mash (not circulating over the grain bed) the first 20 minutes of the mash process.

Remember that poor circulation through the grain bed is not a reason for panic attack, but it might make it more difficult to control the temperature in your grain bed. Consider whether you will be better off by circulating around the malt pipe with no flow over the grain bed and putting the lid on.

Should I stir the grains during mashing?

It is important that all the grains are wet and mixed well with the mash water. If you get a stuck mash, you should stir lightly, but stirring will generally reduce the clarity of the wort.

How often should I tighten the nuts on sensors and heating elements?

It is a good idea to check the nuts regularly. Also check the TC clamps under the main tank regularly.

How do I update the system firmware?

When a new firmware version is available, the system will automatically download it and prompt you to install it. This requires a working WiFi connection and that the MicroSD card is installed. The MicroSD card is installed when the system is shipped and is normally not necessary to remove. If there is no MicroSD card installed, firmware will not be updated.

I cannot connect to WiFi. What is wrong??

Check that the SSID and password is correctly entered. Both are case sensitive. You can also try setting up an access point on your phone to test another network. The system only supports 2.4 Ghz networks.

The pump makes a noise, but no liquid is being pumped

You might have air in your system. Start and stop the pump a few times to vent it. Check that the bottom valve is correctly set. Check that the pump is installed as described earlier. Check for blockages in dip tube or elsewhere.

The pump doesn’t run

Check that the cable is correctly installed and that the pump speed is set to max on the control system. If nothing happens, turn of the pumps, disconnect the cable and remove the pump. Check that no particles is blocking the impeller or that sugars have hardened inside, locking the impeller.

How do I avoid burning the heating elements?

Make sure the heating elements are always covered with liquid. If you do a manual step mash, use the «mash mode » to limit the power output on the heating elements.

Use the link below to read more.

The heating elements are touching the edge of the tank. Is this normal?

No, there is normally a 10-20mm space between the tank wall and the heating elements. If you’ve run the heaters dry, they might have expanded, and the heating elements become more difficult to clean. The minimum distance is 5mm. If the heaters are touching the wall, the main tank might become discolored.

How to adjust the heating elements

The heating elements can axpand if turned on without beeing submerced. When the heating element expands, the distance to the tank wall decreases which makes it harder to clean proporly. To adjust the heating element, use a water pump plier. Wrap the jaw with tape to avoide scratching the heating elements. Tighten each curve of the heating element; 1-2, 2-3, 3-4, 4-5 and so on. We recommend to start off easy and increase tension for each round until the heating element has a perfect curve. If using too much force, the result can be that the curving gets too tight and will cause conflict with the malt pipe. Adjusting back again is not easy.

The selected sensor is showing N/A

If the selected sensor shows N/A on the display, it means the system isn’t reading the sensor. Check the connection and restart the system. If the problem persists, contact the dealer or manufacturer.

Why is the tank and pump sensor showing different temperatures?

The temperature sensor in the pump outlet can be affected by ambient temperatures and will normally show a lower value than the tank sensor. You can correct for this in the software (see the online manual). If you think the sensors have a problem, leave the system in a room with a stable ambient temperature overnight, and check the sensors in an empty system.

I do not get any readings from my 4th sensor (500mm mash sensor)?

• Make sure you are running firmware version 1.6.1 or newer.

• Restart the system after the sensor has been plugged into the AUX port on the controller.

• Open Manual mode and toggle the upper left circular button twice to bring up the sensor reading. Read more about the control system by clicking the link below.

What sensor connects to what socket on the controller?

• Sensor 1: Tank sensor (inside the tank)

• Sensor 2: Pump sensor (Right hand side of the machine. On pump inlet. Used during mashing)

• Sensor 3: Return sensor (Left hand side of the machine. Used during whirlpool and cooling)

• Aux I/O: Mash sensor (Long mash sensor, sold as accessory)

Measuring principle

The density sensor uses a vibrating/tuning fork principle to calculate liquid density based on measured changes in the vibration frequency of the submerged fork. As the fork vibrates, the surrounding fluid's density affects its resonant frequency—denser fluids lower the frequency. The sensor uses this frequency shift to calculate density.

The measuring principle used is commonly used in industries like chemical processing, oil and gas, and food production. These sensors are highly reliable due to their lack of moving parts.

The sensor also measures the temperature with a built-in PT1000 element and uses this temperature as part of the compensation to get the best accuracy.

General design principles

The FCS is built with the demanding and advanced users at mind. It brings a lot of flexibility and customization to the user. All this, presented in an intuitive way, makes it very user friendly.

The 5" touch screen is controlled without gestures like scrolling, swiping, sliding, pinching etc. The system does not use double tap, long press, -just simply single tap.

More advanced functions have explanations available by tapping the (i)-symbol.

All settings are stored and will not change due to power off.

Update

The current software version is shown upon start-up and in the firmware/update settings page.

What is the Troll system?

The Troll system is a product line of brew tables, frames and accessories specifically designed for Brewtools brewing systems and Unitanks.

The Troll brew tables with crane (accessory) is an awesome combination that makes it possible to lift the malt pipe during and after sparging with precision. This is especially useful in locations where having a ceiling mounted lifting device is not possible or beneficial. It can also pivot to allow for the malt pipe to be lowered to an adjacent side table or similar. With the included wheels even more flexibility is added.

The current Troll product line consists of the following main products.

The timer made available in manual mode and recipe mode show remaining time in MM:SS format. Push to set a new time or push and hold to pause the timer. The timer blir start to blink to indicate that the timer is paused. Push and hold once more to resume the timer. When the time is up, the built in buzzer will sound according to the settings. Please see seperate section regarding settings.

The timer used for delayed start is slightly different. As it allows for up to 24 hours, the format is HH:MM:SS to provide a better user experience. Please see separate section for delayed start mode.

Pump control

The pump can be turned ON and OFF using the round button to the left of the slider. The slider is used to control the pump speed.

Heater control

The built-in heaters can be controlled in three different modes. Push the blue text to toggle between the modes.

1. AUTO – PID control limited by “Max current” set in settings menu.

2. MASH – PID control limited by “Mash mode power” multiplied by “Max current” set in settings menu.

3. MANUAL – Manual power control based on slider position. “Max current” set in settings menu define the scaling of power output.

The heaters can always be manually turned ON and OFF by pushing the round button on the left side of the slider.

The PID controller only use one temperature sensor at the time as process input. This means that it uses either the tank sensor or the pump in-line sensor. Indication to what sensor is currently in used as process input is indicated by the text above the actual temperature display.

In settings menu, a «sensor threshold» can be defined. This value is set in percentage and cohere to the pump speed. If the pump speed is set, using the slider, to a value higher than the threshold, the PID controller will automatically switch to using the pump in-line sensor. Similar, if the pump speed is set to a value lower than the threshold, the PID controller will automatically switch to using the tank sensor. This is to ensure that the in-line pump sensor is not used as process input if the pump speed is too low to provide a satisfying temperature control. It is always possible to override what sensor that should be used by pushing the temperature value. Selected sensor is indicated by the text above the actual temperature value. If sensor selection is overridden, the text will be displayed as red as opposed to blue.

Return temperature and mash temperature

In addition to the Tank- and Pump sensor, further two temperature sensors can be connected to the control system.

• Return temperature: This sensor is normally placed on the outlet of the counterflow chiller.

• Mash temperature: This sensor is manually placed into the grains while mashing.

The temperatures can be seen on the display by clicking on the upper left button. This will toggle between:

• Timer

• Return temperature

• Mash temperature

The following pictures show what happens when toogeling between the three displays.

Note that, the heater control cannot be controlled using return- or mash sensors input. At least not for now :-)

Manual control

Manuel mode is where you want to be if you want to have full control and continuous interaction with the equipment during the brewing process. Absolutely recommended as a starting point if you are new to the brewing equipment.

If you want to use the machine as a «Sous vide», manual mode is what you will be using.

From the manual mode screen, multiple functions can be performed e.g. changing the target temperature, toggle between the three heating control modes as well as using the timer. The pump can be controlled manually, and it is even possible to change settings live while brewing. By pushing the button with the snow crystal symbol, the timer will be swapped with the temperature from the third senor (accessory). The timer will still run in the background and by pushing the same button the timer will reappear.

Recipe

Recipe mode allow you to define the whole brewing session and let the control system guide you through the whole brewing process, keeping track of time and temperature. It is possible to store up to 20 custom recipes on the device. A new recipe can be added manually on the device by clicking the plus symbol. Recipes can also be imported from Brewfather by clicking at the Brewfather logo.

More details on how to import recipes from Brewfather, click the link below.

Stored recipes can be edited (pencil symbol), deleted (recycle bin symbol) or executed («play» button). Changes to recipes will not be automatically synchronized back to Brewfather.

Below is an example of how a recipe can look like. By taking the time to type the hop name and amount, you will experience that the text will appear during the brewing process which is of great help.

Recipe name – Give the recipe a proper name to make it easier to find it.

Strike overshoot temperature – Set the strike temperature if you want to compensate for the grain temperature absorption.

Boil time – How long the boil will last.

Cooling target – Target temperature for transferring to fermenter.

Sanitizing time – Get a reminder before the boil time is over to start the pump to circulate boiling wort through the counterflow cooler and hose line to sterilize it.

Mash water – Amount of mash water to be used.

Sparge water – Amount of sparge water to be used.

Sparge temperature – Temperature of the sparge water.

Mash steps – Define mash steps. Maximum 16 steps. Temperature must be incremental for each step.

Boil additions – Dine the additions used during boiling. Maximum 16 additions. Time for each addition is defined as how long it will be boiling. Time must be within total boil time defined above. Text is used as help as it will appear on the screen along the way.

Hopstand additions – Define hop stand. Set time to «0» to skip hop stand.

While running a recipe, notifications will pop up to guide you through the whole brewing session. A selection of notifications will also sound the buzzer according to settings.

Below are some examples of how running a recipe mode will look like.

Delayed start

Delayed start is a mode that allows you to schedule the machine to automatically heat your strike water beforehand, saving time on the brew day. The timer can be set to maximum of 24 hours countdown.

To use it, fill the tank with the right amount of mash water and set the timer to when the heating will start. Remember to allow necessary time for the water to heat, typically 30-60 minutes. When the set point temperature is reached, a safety mechanism is embedded to shut down the power after 4 hours. Time to shutdown will be displayed. This safety feature is implemented in case you forget or for some reason are prevented for conducting the brewing session. An additional safety feature is in place in case the sensors fails while delayed start is active. If sensor fails, the heaters will turn off or not starting at all.

Settings

Settings are made accessible from multiple places in the control system and will allow live changes without interrupting ongoing activity.

Settings are divided into 3 tabs.

General

Under the «General» tab you will find most of the day to day settings.

Alarm beeps – Number of beeps when the buzzer is activated. Choose; none, 1,3,5 or continuous.

Brightness – Select screen brightness in 20% increments from 40% to 100%.

Language – Select language. English, Norwegian, Italian, German, Spanish or French.

Sensor Threshold – Set the pump speed threshold where the in-line pump sensor automatically will be used as opposed to tank sensor as process input for temperature control. Select either 20%, 30%, 40%, 50%, 60% or 70%. It is still possible to override this, please see heater control section further up.

Max current 1 – Set the max power draw for power input 1. It is recommended to set it according to amperage rating on the circuit breaker feeding your power outlet. Available settings are: 10A, 13A, 15A and 16A.

Max current 2 – Set the max power draw for power input 2. It is recommended to set it according to amperage rating on the circuit breaker feeding your power outlet. Available settings are: 10A, 13A, 15A and 16A. Note! B40pro 240V version does not use this setting as it only has one power input cable.

Temperature unit – Select Celsius (°C) or Fahrenheit (°F).

Volume unit – Select Liter or US Gallon (1 US Gallon = 3.785 liters)

Mash mode power – Select power limitation used in Mash mode. This is a nice feature to reduce or avoid burning of the heating elements is cases of using wheat grains and/or step mash programs. Toggle to select either 30%, 40%,50%, 60%, 70%, 80% or 90% power during mash mode. The power reduction is related to any additional reduction set in Max current setting, so make sure total power available is enough to keep a stable temperature or perform a temperature increase during step mash at preferred pace. Other factors that will play a role is: surrounding temperature, whether lid is on or off, use of insulation jacket, volume in the kettle and voltage. It is recommended to test this prior to starting the brewing session, especially if you plan to use recipe mode as it will not allow you to change this on the fly.

To enable the power reduction, now called; mash mode, please see heater control section further up. If the text “MASH» is shown below the target temperature, you know it is activated. You will also see that the power slider indicator on the screen is locked to not exceed the percentage value set. For recipe mode, the system will automatically select mash mode.

Sanitizing time - Select how long before the end of boil the system should notify user to start circulating through the countercurrent cooler to disinfect the equipment. The value is used by default every time you create a recipe on the device or in cases where it is not defined when a recipe is downloaded from Brewfather.

Strike overshoot temperature - Select how much warmer the water should be for strike to compensate for the temperature effect of the grains when it is poured into the brewing machine. The value is used by default every time you create a recipe on the device or in cases where it is not defined when a recipe is downloaded from Brewfather.

Wi-Fi

To connect the device to a 2.4GHz Wi-Fi network with internet access, you will have to consent to Brewtools collecting anonymous data for the purpose of improving the services. Consent is given from the screen before filling in SSID and password.

Note! SSID is case sensitive meaning it distinguishes between small and capital letters. Additionally, some special characters are not supported by the system. Please check the keyboard on the device for allowed special characters.

Connection status is shown to the right. To disconnect the device from Wi-Fi, press the thick box. Last used SSID and password will be stored locally at the device.

Update

If the device is powered on and connected to internet, it will download new firmware as it become available:

• microSD card is installed in a slot on the backside of the control box.

• Connected to internet.

To check whether the device is downloading an update, please open the «Update» tab. When a new firmware is downloaded, user will get a notification. User then decide to install immediately or next time the device is powered on.

Secret settings

A secret settings menu is available from Manual mode or Delayed start. By pushing and holding the B-logo for more than 3 seconds you get access to settings that are considered more advanced and normally not relevant for most users. Offsetting temperature sensors and changing the PID controller parameters should not be done unless it is familiar to you.

Push «SHOW» button to see the default PID parameters.

From firmware version 1.6.0, standard PID parameters were changed to reduce temperature from overshooting/exceeding the target temperature.

Introduction

Our Brite tanks are perfect for storing, maturing, clearing and carbonating beer. Designed with basis from our well proven Unitanks, pressure rated up to 2 bars and with enough ports to support future accessories. Key points:

• Closed transfer from fermenter to minimize oxygen exposure.

• Pressure controlled process using a spunding valve or .

• Forced carbonation.

• Closed transfer to keg, canning or bottle fillers.

• Use it as a serving tank.

• Temperature control using a glycol chiller.

In addition to this, our Brite tanks offers:

• Built in cooling jacket for easy cleaning and efficient cooling.

• TC 8" top port for easier cleaning.

• TC 2" bottom dump port with butterfly valve.

• 3 x TC 1.5" (DN32) ports below the cooling jacket for sensors and racking.

Brite light

Polyketone (POK)

Polyketone (POK) is a plastic material that is food grade, extremely durable and can withstand high temperatures (220°C melting point) and acids. This vastly reduces cost without compromising the user experience.

Models

Our Brite tank series currently consists of 4 models based on the same design principles, but with different capacities. The name of the tanks reflects the tanks approximately gross volume in liters. All Brite tanks feature the same ports and and functions. The two smaller models (Brite 40 & Brite 80) have an 8" to 3" adapter on the top, and the larger models (Brite 150 & Brite 300) have a 8" to 4" adapter.

Dimensions

This is included as standard

• 1 pcs Analog pressure gauge, TC34mm including. 5 pcs membrane gaskets.

• 1 pcs TC34mm PRV, 2 bar (Brite light has a pull-type PRV/Safety valve with 7mm barb)

• 1 pcs Butterfly-valve, 2" (Brite light models comes with POK valve)

• 1 pcs TC elbow 90°, 2"

Accessories (sold separately)

Assembly

1. Unpack the Bright tank. Please recycle packaging.

2. Flip the tank upside down, resting the top port on a soft surface.

3. Install the four M10 steel/rubber feet.

4. Install the 2" elbow, pipe and butterfly valve.

First time use

The tanks use our PureBlast™ surface on both the inside and the outside. This is what gives the matte surface. The surface has no polishing residue or wax but should be cleaned with warm water and a cloth to remove potential dust from the blasting process.

Fittings and valves should be cleaned well before first use.

As usual, the tank must also be sanitized with Star-San or similar before it is used.

Cooling setup

It is possible to use several of the glycol coolers that are on the market today. Check out our product selector by clicking on the link below.

In use

The tank is always washed and disinfected before use.

If the storing, maturation is to take place under pressure, a spunding valve must be used. Set this to the desired pressure.

The Sample valve is ready for a coil on the spout so that you can pull samples from the tank under pressure without too much foam being formed (sold separately).

When the cooling jacket is in use, condensation of moist air can lead to water dripping on the floor. It is therefore recommended to use the neoprene insulation jacket to minimize condensation.

Cleaning

When the tank has been emptied, make sure to release any overpressure in the tank and keep it open so that air can come into the tank unhindered. Do a first clean with cold tap water to remove eny remainings.

For the second cleaning step it is recommended to use CIP and a caustic cleaning agent like PBW. The same solution used on our brewing systems and fermenters will work with our brite tanks:

• TC 4" CIP adapter (7712544) or TC 3" CIP adapter (7712755)

• CIP-ball, 1/2" F-NPT (7712545)

Using a powerful pump, connect the pump intake to the bottom of the brite tank and the outlet to the CIP adapter to the top of the fermentation tank.

Overview

• Baud rate: 1 Mbps

• Device data transmission interval: 10 ms (100 Hz)

Wiring & Connections

We use a 5-pin connector on all our CAN devices. For most devices, the 4th pin is not in use.

The devices require a stable 24V DC power supply.

Wiring of each CAN line should be done with a single long line and short stubs to each sensor. Use a 120 resistor shortly after the last device.

Setup Process

Our design support 8 of the same device type per CAN bus (node ID 0-7). All devices are shipped with node ID 0, so in order to have multiple devices on a single CAN bus you need to assign each one a unique node ID (described in detail in ). The easiest way to do this, is to connect the first device, give it node ID 1, then connect the next one - give it node ID 2 and so on until you have reached 7, and then the last one can keep node ID 0. If you have 8 density sensors, the result should look like this:

1. Density sensor @ node id 0

2. Density sensor @ node id 1

3. Density sensor @ node id 2

4. Density sensor @ node id 3

The same procedure goes for other devices.

CAN ID and Message Design

The CAN messages use the extended CAN ID format of 29 bits. It contains information about the message priority, sender node type, receiver node type, secondary node id and message type:

• priority (Priority: 2 bits - 4 values) = 2/29 bits

• senderNodeType (Sender Node Type: 8 bits - 256 values) = 10/29 bits

• receiverNodeType (Receiver Node Type: 8 bits - 256 values) = 18/29 bits
