Rooftop packaged units (series APCC, APCA and APSA) consist of an air handling unit with DX (Direct Expansion) evaporator coil and a condensing unit including a compressor, condenser and refrigeration cycle equipment; it can use a heating coil for cold seasons as well. These air conditioning models are suitable for such places as shops, community halls, industrial/sport/exhibition complexes, and indoor amusement parks.
