3. Fermenting room

If you brew your own beer, you know that maintaining the perfect temperature for fermenting matters — a lot. And if you’re brewing at home, having a walk-in cooler to store your growing beer collection can help you stay organized, so you can keep the beer flowing.

9. Curing chamber

If you already cure meat at home, you know temperature, humidity, and air flow is paramount — and that simply hanging sausage in your garage doesn’t suffice. With a walk-in cooler, you can easily control the temperature and humidity to get a safe, decent product.

10. Emergency shelter

Besides storing food, a walk-in cooler can provide a safe place if a natural disaster strikes. Just ask Amber Bradshaw. Though most of the time, she uses her cooler for food, it came in very handy as an emergency shelter when her region was hit by a hurricane last year.

  1. Just finished mine for Maple Syrup a month ago! LOVE IT. It now also does all my beer, and extra food storage. This little bot rocks!

  2. im concerned that the heat and humidity coming out the back end of the AC unit will warm the room in which the cooler is located. Have any past constomers compained of this? I am a baker and would like to install a small (4’x4′) cooling chamber in my baker to slow ferment my doughs, but am concerned that the AC unit will make the bakery space to warm and humid

    1. Hello Andrew,

      Usually not an issue at all with a CoolBot driven system. Using the CoolBot and Air Conditioner combination for a smaller space and with good insulation will result in minimal cycling time and a much smaller power generation surface vs. traditional sources. I will email you my cell phone and look to connect and discuss the project. We are honored to be part of it and thank you.

  3. We would like to build 2 walk-in cold rooms (stationary and mobile), to store farm fresh vegetables and fruits, using prefabricated humidity-resistant panels, expanded polystyrene, aluminium composite panels and galvanised metal Square pipes. the other thing is that we are in West Africa; will the COOLBOT and window unit suffice under our humid climatic conditions?

    1. Hello Andrew, we would be excited to be part of the project and yes; the CoolBot / AC combo is a viable solution for your environment. We have over 40,000 CoolBots running in over 70 countries. Please email us your contact information at and our Director of International Sales will reach out you.

      With much appreciation,
