Cool Boss CB-20

Did you know that OSHA law requires employers to provide a workplace free of heat exposure risks? That’s where the CB-20 shines; keeping your employees cool when temperatures rise. The Cool Boss CB-20 portable evaporative air cooler uses plain tap water to chill stifling hot air up to 26-degrees F cooler for about a buck a day. Its automatic fill system, combined with a 20” fan, automatic swing louvers and soft-touch LED digital controls make the CB-20 an easy to use and very efficient space-cooling solution.

The CB-20 operates on standard 110-Volt household power and features three fan-speed settings precisely deliver just how much cool air you need, and a powerful 1/3 HP motor circulates the air through a very capable air-pushing 20” diameter Blue Flex™ fan. The axial-flow design and flexing nature of the fan blades pulls more air at idle, while reducing engine drag at high rpm’s for peak performance and cost-saving efficiency.

Unlike traditional shop fans, Cool Boss coolers do more than just move hot, stale air around. They cool and condition the air. The CB-20 evaporative cooler uses Honeycool™ evaporative media pads that soak up water like a futuristic sponge. Their unique hexagonal prismatic shapes are highly functional, very strong and allow air to pass through. As warm air passes through the honeycomb media pads, it mixes with the water which in turn evaporates, resulting in a constant flow of fresh, cool air providing a more tolerable and much fresher working environment.

Featuring an auto-refilling 15-gallon cold water reservoir, the CB-20 air cooler delivers a constant supply of chilled air that can be directed towards a concentrated area or oscillated back and forth through a built-in automatic swing-louvers. With an incredible 5,297 CFM of air pushing volume combined with a max area coverage as much as 1,076 square feet, you’ll quickly see just how easy and affordable it is to cool large spaces. Thanks to its sturdy high-density polyethylene (HDPE) housing, Cool Boss receives superior damage protection as well as resistance to sunlight and UV rays.

The Cool Boss CB-20 is small enough to fit almost anywhere; it’s simple to operate and inexpensive to run; and it blows cool air like a winter storm. What more could you ask for?
