KwiKool KCA4221 – ceiling-mounted – 42,000 BTU/h – 3.5 ton air-cooled


Runs on 230V 40 amp circuit

The KwiKool KCA4221 (nominal 3.5-ton or 42,000 BTU) is in The Ceiling Master Series, KwiKool’s Permanent Line of Above-Ceiling Mounted units.

With its no-frills features, high sensible cooling, and extremely small size, the KCA4221 is the perfect solution for cooling small server and IDF rooms, especially when floor space is limited. The Ceiling Master Series, KCA air-cooled models, perform and out last the competition with its small size, high efficiency, and lower cost.

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 KCA4221 runs on a standard 230-volt/40-amp single phase 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.
