This unit features single or dual compressor(s) and a vertical discharge air-cooled condenser that is suitable for large walk-in coolers and freezers, blast freezers, warehouse applications and air conditioned spaces where roof mounted condensers are most practical. Using high efficiency compressors and utilizing the THERMOSPAN™ condenser core design, the unit meets all application needs from 15 to 100 Hp (high and medium temperature) and 10 to 80 Hp (low temperature).


    • 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.
