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 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 6 to 40 HP (high/medium temperature) and 7.5 to 44 HP (low temperature).


  • Compatible with Low GWP Refrigerants
  • Designed for use with a wide variety of refrigerants
  • Energy efficient compressors with POE. Several Options to choose from: Copeland Discus, 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.
  • Receivers (where used) are liberally sized and include inlet as well as outlet service valves
  • Subcooling circuit in condenser on all models (except high temperature 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, 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.
  • Units are environmentally friendly operating on less power and refrigerant charge.
