Unitanks
F40 / F80 / F100 / F150 / F300
Introduction
Our Unitanks are fermenters you can ferment, carbonate and serve your beer from. They are pressure rated and offers a lot of functionality.
Pressure controlled fermentation using a spunding valve.
Dry hopping with minimal exposure to oxygen.
Forced carbonation.
Closed transfer to keg or bottle.
Use it as a serving tank.
In addition, they offer the more traditional features like:
Yeast harvesting from bottom or top.
Temperature control using a glycol chiller.
In addition to this, our unitanks offer:
Built in cooling jacket for easy cleaning and efficient cooling.
TC 2" Heating element port (accessory) for high temperature fermentation.
Additional TC ports for accessories.
PureBlast™ surface inside and out for easier cleaning, lower risk of hidden micro-pore contamination and no need for passivation, unless you ferment highly acidic beer or fruit juices.
Several of the listed functions of our Unitanks will require accessories that are not included as standard. Please see separate section on what is included.
Unitank Light
Unitank Light models have the same tank body as our standard Unitanks, but with slightly different set of accessories to make it more cost effective.
The following parts have been removed as standard:
Neoprene jacket
The following parts have been changed:
The standalone PRV and the blow-off pipe with TC34mm butterfly valve has been replaced by a PRV with a 7mm barbed connector and a 6x10mm silicone tube.
The following parts are made from polyketone (POK) instead of stainless steel:
TC adapter (8" - 3")
Sample valve
Racking arm
2" Butterfly valves
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 Unitank series currently consists of 6 models based on the same design principles, but with different capacities. The name of the tanks reflects the tanks gross volume in liters. All Unitanks feature the same ports and and functions. The two smaller fermenters (F40 & F80) have a 8" to 3" adapter on the top, and the larger tanks have a 8" to 4" adapter.

Ball Lock adapter to add CO2 for purging, force carbonation or closed transfer to kegs.
Carb stone kit for forced carbonation.
Coil for sample valve for getting samples with less foam.
3" (F40 & F80) or 4" (F100 ->) HopDrop kit.
Spunding valve for pressure control.
Hose barb and silicone hose for filling, dumping and blow-off tube
TC 2" sight glass.
CIP ball with 4" or 3" CIP adapter.
Desired fittings for cooling jacket (if using glycol chiller).
Assembly
Unpack the Unitank. Please recycle packaging.
Flip the fermenter upside down, resting the top port on a soft surface.
Install the four M10 steel/rubber feet.
Pull the telescopic legs up to get the preferred height and use the eight M8 bolts to secure it.
Flip the tank right way up and mount the TC 2" 90 degree elbow and 2" butterfly valve to the cone.
Mount a TC 2" blind cap on the left side port (positioned under the cooling jacket fittings).
Mount blind plugs on the TC 1,5" ports on the right side.
Mount TC 2" racking arm and TC 2" butterfly valve on the conical port pointing forwards. The adjustment pin on the racking arm is pointing the same way as the racking tube.
Mount the sample valve on one of the forward facing 34mm TC ports.
Mount blind caps on the other two forward facing 34mm TC ports.
This step is not applicable for Unitank Light: Decide if you want the Blow-off tube on the left or right side of the fermenter. Mount the Blow-Off tube on one of the top front 34mm TC ports. Mount the TC pipe holder accordingly in one of the two threaded holes on the top of the leg using the attached M6 bolt. Fit the back grommet around the blow-off pipe and lock it into place with the TC pipe holder.
This step is not applicable for Unitank Light: Mount the TC34mm butterfly valve to the lower part of the Blow-Off tube.
Mount the safety valve (PRV) on one of the available top 34mm TC ports.
Mount the analog pressure gauge on one of the available top 34mm TC ports using the attached blue membrane gasket. It is important to make a small hole in the center of the blue membrane gasket before use.
Mount a blind cap on the last top TC 34mm port.
Mount the 8" to 4"/3" adapter. Use the attached tool to tighten the 8" clamp further to ensure it is pressure tight.
Mount a 4" or 3" blind cap on the top.
Mount any additional accessories.
First time use
The fermentation 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.
Always check for leaks before use.
Passivation is normally not a requirement with PureBlast™ surfaces but if you ferment highly acidic beer or fruit juices, we require passivation to protect the steel.
Safety valves should always be tested before use to ensure correct function.
The easiest way to test it is to directly connect a ball lock connector to the tank side of the safety valve and pressurize it using air or gas.
Tanks made from 304 stainless steel, are not designed to ferment liquids with a pH under 4.0. We do not recommend fermenting apple juice or other highly acidic liquids in tanks made from 304 steel. Doing so is at your own risk and will void the warranty of the product.
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. Transfer of wort is done through one of the lower 2" ports. Make sure that the Blow-Off pipe is connected and the 34mm blow-off pipe Butterfly valve is open so that the air in the tank escapes and does not create back-pressure for the pump. When filling is complete, use a hose connection from 34m Butterfly to a bucket of water to form an airlock during fermentation.
If the fermentation is to take place under pressure, a spunding valve must be used. Set this to the desired pressure, normally a maximum of 1.1 Bar / 16PSI. In this case, the Blow-Off pipe must be closed.
Always make sure that the safety valve (PRV) is fitted as this ensures that the pressure inside the tank never exceeds the pressure for which the tank is designed and approved.
The safety valve is designed for 2 bar / 30PSI +/- 0.2 bar / 3 PSI
Do not open the safety valve or make adjustments to it.
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.
The cooling jacket is not designed or manufactured for pressure. Only use pumps made for this type of use. Never connect tap water.
Dumping of yeast and hops is done through a lower 2" valve before transfer to a keg or maturation tank. Transfer to kegs is done through the second lower 2" port where the racking arm is mounted.
During cleaning and emptying, the tank must be vented so that air enters freely through Blow-Off pipe. If this is not done, a vacuum will occur and the tank can ultimately implode.
For Unitank Light, please avoid using excessive force on the valves. Make sure to turn the valve handle and not pull or push on it as this may cause the POK racking arm to break.
Cleaning
When the finished beer is drained, there will be 1-2 liters left depending on the connected equipment on the lower 2" flange and position on the racking valve. Release any overpressure in the tank through the valve on the Blow-Off pipe and keep it open so that air can come into the tank unhindered. Drain what may be left in the tank and remove what may be mounted on the 8 "flange on top of the fermentation tank. Do a first clean with cold tap water to remove most of the hops and yeast.
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 will work with our fermenters:
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 fermentation tank and the outlet to the CIP adapter to the top of the fermentation tank.
Remember that the valve for the Blow-Off pipe must be open to avoid vacuum.
