General Details
The Model KCA3021 (nominal 2.5-ton or 29,500 BTU)  is designed to be the smallest unit possible for its capacity. The Ceiling Master Series is KwiKool’s Line of permanent mount, above-ceiling units. With its no-frills features, high sensible cooling, and low profile, the KCA3021 is ideal for places with high heat loads and limited floor space. Your solution for cooling small server and IDF rooms, video editing studios, auto, and airline repair staging areas, telecom closets, and areas with a high concentration of electronic equipment. KCA air-cooled models are easy to install, and made to out-perform and out-last the competition.

The built-in mounting supports on the unit’s base allow for easy installation by a qualified mechanical contractor above a drop ceiling, using standard, off-the-shelf hardware. KwiKool’s self-contained design also eliminates the need for refrigerant connections, further reducing installation costs. All Ceiling Master Series units come with three mounted flanges, which allow duct connection for hot air exhaust, and cold air supply and return. The KCA3021 runs on a standard 230-volt/20-amp circuit and uses any 20-volt thermostat. The condenser is powered using direct drive motors, eliminating any belt maintenance. The unit also comes with an internal high lift condensate pump.

And, KwiKool products are proudly MADE IN AMERICA.
