Certification:
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.
