Cool Boss CB-24

One of our most popular selling units, the CB-24 is the perfect balance between size and cold air delivery. Hanging out in the backyard with friends and family? Maybe you’re planning an outdoor event during the hot and dry summer months. Whatever your air conditioning needs are, the Cool Boss CB-24 is sure to help make your friends, family, and guests feel a lot more comfortable.

The CB-24 is small enough to save valuable floor space, but still large enough to deliver some serious cold air. Use it in the shop or garage to keep you and your workers happy and more productive, all the while saving money compared to other air conditioning options. Auto repair work is hard enough when the air around you is comfortable, but when the temperature climbs, it’s hard to concentrate and stay productive. Cool Boss evaporative air coolers are the perfect solution for any vehicle repair operation or home garage; and much better than fans that simply recirculate hot stuffy air around the room. The CB-24 will help reduce heat from climbing weather temps, hot-running welders and machinery, and create a cool working environment. Roll it around the shop as you move between bays and other workspaces.

For less than a dollar per day, the portable Cool Boss CB-24 chills surrounding air temperatures by as much as 26 degrees. It’s powered by a 1/3 HP motor that circulates air through a generous 24” diameter Blue Flex™ fan. The axial-flow fan blades design pulls more air at idle and reduces engine drag at higher rpm’s for better performance and energy efficiency. Who would have thought that something as simple as fan blade design could save you more money? How cool is that?

With a plentiful auto-refilling 19-gallon cold water reservoir, the CB-24 evaporative air-cooling system delivers a constant supply of chilled air that can be directed towards a concentrated area or oscillated back and forth through built-in automatic swing-louvers. With an area of coverage as much as 1615 square feet, you’ll quickly see just how affordable it is to cool very large spaces. Three fan-speed settings precisely deliver just how much cool air volume you need. Honeycool™ evaporative media pads provide a very durable, and long-lasting cooling solution.

The CB-24 operates on standard 110-Volt household, is sporting a durable High-Density Polyethylene (HDPE) housing which provides superior damage protection and resistance to sunlight and UV rays, and is simple to operate and inexpensive to run, even for long hours. Finally, you can have your space and cool it too!
