Features:

• Compatible with Low GWP Refrigerants
• Units are CULUS Listed.
• Designed for use with various popular refrigerants.
• Energy-efficient compressors with POE or mineral oil.
• Several compressor options to choose from: Copeland Discus and Bitzer reciprocating.
• Single, Dual and parallel-piped (optional) compressor configurations available.
• ThermospanTM condenser core design eliminates tube sheet leaks and provides reliable operation.
• 3/8″ condenser tubes reduce refrigerant charge.
• Generously sized condenser allows unit to operate at higher than normal ambient conditions.
• Optional coating and fin surfaces for condenser core protection available.
• Specially designed, thermally protected and permanently lubricated ball bearing condenser fan motor(s).
• Receivers (where used) are liberally sized and include inlet as well as outlet service valves.
• Subcooling circuit in condenser on all models (except on H8 models) increases overall system efficiency and provides dependable compressor operation.
• Utilizes pre-formed internal piping, eliminates welded joints and reduces chances of a leak.
• Electrical components are housed in a spacious and conveniently located panel. In case of a compressor trip, (except on air conditioning models) a lock-out relay de-energizes the liquid line solenoid valve. In addition, SPDT contact is provided for field-wired alarm circuit.
• End compartment panels allow unrestricted access to service the compressor(s) and all other components.
• Raceway for pressure control wiring and connections provides neat appearance.
• Units are available with energy-efficient ThermosaverTM hot gas defrost option.
• Units are environmentally friendly operating on less power and refrigerant charge.
