Details
The CoolBot is a patented electronic controller that enables its users to turn an insulated room into an affordable walk-in cooler, using only a CoolBot and an off-the-shelf air conditioning unit.

CoolBot for Brewers

You can build an affordable walk-in cooler for brewing by using a CoolBot and a standard air conditioning unit. Whether you're fermenting, lagering, or just keeping your brews cold for drinking, the CoolBot can help you with your cooling needs.

Save money on upfront costs, monthly electricity bills and expensive technician visits compared to a traditional walk-in cooler.

CoolBots are used by homebrewers, nanobreweries, microbreweries and craft breweries all around the country, as well as the bars, pubs and restaurants that pour their beers.

How it Works

The CoolBot utilizes the cooling power of a standard air conditioner to drop the room temperature as low as 33°F without freezing up the air conditioner fins.

All that is required to implement a CoolBot driven system is (1) a room insulated to a value of R25, (2) a standard window or minisplit air conditioner and (3) a CoolBot. 

CoolBots are best suited for coolers that are opened less than 6 times per hour. Accordingly, it is a great solution brewers, wine cellars, cheese caves, and more.

Reduced Upfront Costs: A CoolBot and a standard A/C is up to 83% cheaper than traditional technology, saving users $1,000s on their refrigeration equipment

Lower Operating Costs: A CoolBot-driven system uses up to 42% less electricity than the traditional technology, saving users $100s - $1,000s per year on electricity


In addition to CootBot's Construction Guide and A/C Selection Guide, here are a few tips for how to best use a CoolBot in your brewing:

Fermenting: Many brewers ferment their beer at around 50°F - no problem for a CoolBot.

Lagering: For brewers who needed to lager their beer at ~34°F, CoolBot has a few suggestions:

  1. Insulate all surfaces (ceiling, walls, floor) to at least an R value of 25. Rigid foam paneling is the best insulation material.
  2. Use plenty of caulk and spray foam to seal every gap, crack and seam to prevent air leakages.
  3. Install a well-sealed door gasket.
  4. Try to limit door opening to less than 4 times per hour.
  5. If you're still having a hard time reaching 34°F consistently, add another A/C unit and CoolBot to increase your cooling power. This will also add some redundancy to the system in the event of an accident.

Fermenting and Lagering

Some brewers need the ability to switch between higher and lower temperatures (~35°F to ~60°F) for their brewing process, so they need to have larger A/C units to get down to these low temperatures. The issue is that once the cooler reaches the low temperature (~35°F), it becomes difficult to increase the temperature in the cooler to the high temperature (~60°F).

For these cases, CoolBot recommends a pass-through thermostat. You can plug the A/C through the pass through thermostat, so that as soon as the room hits the set temperature on the CoolBot, the power is shut off to the A/C. Leave the CoolBot plugged in as usual. If you opt for this set up, you must purchase an A/C that can automatically restart after a power failure (some automatically reset to 70F). 

Running Taps

The CoolBot is great at keeping your tap room at the right temperature - cold and refreshing, but not too frothy. Be sure to insulate around the tap lines, either using spray foam or foam pipe insulation.

Flooring

If you are wheeling kegs in your cooler, a concrete floor or plywood coating over insulated foam will be good to spread the weight load. Be careful if you are using any keg racks with pointed ends - you will want to put extra plywood or metal underneath to spread the weight.
