The 07D condensing unit is designed for a wide range of commercial and industrial air conditioning and refrigeration applications. They give the engineer great design flexibility, since they can be combined with a wide variety of coils or chillers to provide a cooling system that closely matches actual load requirements. This results in an energy-saving system that operates efficiently at maximum load conditions. The rugged 07D units have a serviceable reciprocating compressor, shell and tube water-cooled condenser and controls, combined with all interconnecting piping and wiring. Easily installed, they require only simple external piping and wiring, and occupy little floor space. When connected to a matching Carrier fan-coil unit these condensing units provide a quiet, dependable air conditioning system.
