Air cooled chillers cool by a fan blowing air over a condenser coil converting the refrigerant from a gas state to a liquid state. The refrigerant then runs through an evaporator cooling the liquid in the evaporator, that liquid then flows to the reservoir tank. The compressor pushes the refrigerant through the system. Air cooled chillers have a small footprint with a compact design. They do not require a water tower with associated water pumps, piping and fans, reducing installation and maintenance costs. Air cooled chillers are easy to install, just plug them into a power source and they are ready for use. These chillers are the standard for smaller facilities.
