BIAB Controllers


Electric BIAB (Brew In A Bag) Controllers


Our BIAB controllers are designed to manage your entire BIAB process mash without breaking the bank. With an electric BIAB controller you control your mash, and boil all with one heating element managed by one controller.


The one real advantage to BIAB is after your mash is done you lift out the grain bag, let it drain and start your boil.


With our controller you just flip the mode switch up to boil, turn the boil knob all the way up until you start boil then adjust the boil knob to the boil rate you want – and assuming you have a way to hang your grain bag above your pot, all while your grain bag is still draining!!! There is nothing to unplug, plug in or to switch over. And there are no controller settings to fiddle with. Controls are simple and the boil control knob is sensitive enough to set exactly where you want.


Note: Some customers use our BIAB controller as a conventional brewery controller by swapping elements. They plug in their mash tun for mash, then unplug their mash tun and plug in their boil pot for boil.


Our standard BIAB controller is available with a GFCI compatible 4 prong plug and we strongly recommend this choice for GFCI protection. This controller will work with a GFCI protected or non-CFCI protected 4 prong dryer outlet.


But we understand that many home brewers use a dryer outlet as a their power source and most older dryer plugs are 3 prong, so we also offer a non-GFCI compliant 3 prong version of our BIAB controller.


Our BIAB controllers feature:

A compact all aluminum housing with 4 mounting holes and large heat sink to dissipate excess heat. We never, ever use unsafe plastic housings for our brewery controller products.
A twist right to turn on / press to turn off main power button that also serves as an emergency off switch.
Boil is managed with our in-house designed PWM controller – the graduated knob on the top panel.
Temperature is managed by an off-the-shelf PID controller. We could design our own controller but sometimes it’s just smarter to let the experts manufacture and deliver what they do best!
Ships complete with a in-house designed PT-100 temperature sensor. Our temperature sensors are built into their own water proof thermowells with 1/2″ MPT type threads and nylon lock nuts. We include a 6 foot flexible sensor cable that can be easily disconnected and reconnected at either end.
Simple to use BOIL / MASH switch changes modes during your BIAB brew cycle.
Features a 10 Gauge SJOOW 12 foot power cord with a 4 prong dryer style power plug.
Also features one 30 Amp L6-30r twist lock receptacle designed for a L6-30p twist lock plug used by most 240V BIAB home breweries.
One 120V pump control circuits with separate on/off switch and pump outlet. The pump is switched separately. You can use other pumps but we recommend MARCH pumps for our controllers.
A programmable alarm with it’s own on/off switch. The alarm is about as loud as a smoke alarm alerter and it makes about the same sound.
All of our controllers are tested with GFCI and are GFCI compatible.
The safety ground wire that runs from the outlet all the way to the plug is also bonded to the aluminum housing for safety.
All of our controllers are 100% manufactured in the USA with a mix of US, Chinese and Canadian components.

Specifications and Installation Recommendations:

Our standard 220/240V BIAB controllers are built with 4 prong dryer type plugs, with 3 prong versions available. Like all of our other controllers, these are 100% tested behind GFCI breakers and to be 100% GFCI compliant our 220/240V controllers must be 4  wire. We highly recommend running a dedicated GFCI protected 30 Amp 4 wire circuit for your brew area. NEC Code in most areas will require you to run 4 wires to a sub panel and one of the best choices on the market is a SPA panel. This controller will easily handle up to a 7000 watt heater after factoring in power for a circulation pump.

Even though this controller can handle up to 7000 Watts, many BIAB systems are lower volume and we recommend sizing your BIAB element to match your boil volume.

2 – 3 gallons = 2000 – 3500 Watt
3 – 4 gallons = 3500 – 4500 Watt
4 – 6 gallons = 4500 – 5500 Watt
