CoolBot Cooler Controller

A CoolBot allows a standard air conditioner to cool a room or space down to 35 degrees F.  Installs with no tools or electrical knowledge required.  

Standard A/C units available from any hardware or appliance store have lots of power but they are electronically limited so that they cannot go below 60 degrees F. This is because they would freeze up. Commercial refrigeration for walk in coolers combat freeze with increased surface area on the fins as well as fans. Instead the Cool bot technology uses multiple sensors, a heating element and programmed micro-controller to control your air conditioner in such a way that the unit can go below 60F and not freeze up.  The Coolbot cannot give you 100% of the btus listed on your air conditioner nor is suitable for large brewery or winery walk ins. It is perfect for wine cellars, beer storage, fermentation, etc. 

Easy to install within 30 minutes with no tools or electrical knowleged required. While we can't tell you exactly what size space you can cool because of ambient temperatures and insulation factors, we recommend you google Coolbot. They have sold over 50,000 of these so there are lots of reviews and actual installs out there. We offer free shipping on this unit, ship fast from both coasts, and have great customer service.  

This type of system is also very efficient. Most commercial systems are power hogs with large fans that are always running.  Residential A/C units are made for efficiency. The Coolbot will also shut down the compressor for short time when the unit is running at its highest level of inneficiency, as it nears freeze up.  

• Dims of the CoolBot are 6.5x3.5x1.5 in. 

Introducing the Revolutionary CoolBot     Build your own walk-in cooler using just a window air conditioner, a well-insulated room and the CoolBot. Over 45,000 units sold and used in 70 countries around the world.	Build Your Own Walk-in Cooler     Easy to install and set, the CoolBot allows you to cool a well-insulated room from 59 degrees F down to 34 degrees F, saving $1,000s compared to traditional cooling systems.

How It Works     The CoolBot is a patented microcontroller that enables your air conditioner to chill a well insulated room or trailer down to 34 degrees F.

How the CoolBot Temperature Controller Works 

The CoolBot transforms any well-insulated room into a walk-in cooler by harnessing the cooling power of a standard air conditioner.

Traditional walk-in cooler refrigeration systems sell for $7,000* with installation and

electrical setup. Traditional systems use a “brute-force” approach to cooling: lots of coolant (which is bad for the environment), a big motor, a large surface area, and multiple fans (which can dry out your vegetables and account for up to 60% of the cost of operating electricity).

Here’s the crazy thing: That $3,500+ walk-in cooler compressor you see on a small 8′ x 8′ vegetable cooler may only put out 8,500 BTUs of cooling power! That’s fewer BTUs than you get from a $600 window air conditioner from Home Depot!

Why not just use an A/C unit then? First, they are electronically limited so that they can’t go below 60° F. With some electrical bravery and skill, you could snip, solder and bypass the electrical controls so you could go lower. It will work better, but still not very well as your ability to actually utilize that cooling power drops drastically as you approach 60° F. This limitation at 60° F vs. a traditional walk-in cooler refrigeration system is driven by the lack of extra fans and surface area built into traditional walk-in cooler compressor / condenser / evaporator units which dissipate the cold without freezing up the fins of the unit.

The CoolBot’s patented technology intelligently controls your air conditioner – so you can harness its cooling power and keep temperatures in the 30s without freezing up your air conditioner.

The CoolBot uses multiple sensors, a heating element and a programmed micro-controller to direct your air conditioner’s compressor to operate in a such a way to cool the room to 36° F without ever freezing up. Additionally, our innovative interface which links the CoolBot controller to your air conditioner allows for 5 minute installations without any training, cutting, soldering or even taping.

CoolBot cannot give you 100% use of the listed BTUs on your air conditioner, so you will need to buy a higher BTU air conditioner than the BTU size you would buy on a traditional cooler compressor. However, the price of a larger air conditioner and a CoolBot is a fraction of the cost of a real walk-in cooler compressor, saving you $1,000s in upfront equipment costs.

Most importantly, when the CoolBot begins to lose efficiency when accessing your BTUs of cooling power (when the air conditioner is close to freezing), it is programmed to shut off the compressor on your A/C unit, so you do not pay for electricity to make BTUs that you can’t use! That saves you money on your monthly electricity bill and helps the environment. As long as you sized your air conditioner correctly and insulate your cooler well, you’ll have no problem keeping your room as cold as you want it to be.
