Overview
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).
Features/Options

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.

Standard features include:

  • Spring mount compressor with discharge vibration eliminator.
  • Compressor head cooling fans on low temperature models (except L8 units)
  • Compressor crankcase heater
  • Flexible hose on all compressor pressure control connections
  • Two valve adjustable (pre-set at factory) low ambient head pressure control.
  • Condenser fan cycling control (pressure) on two-fan models and up.
  • Fused condenser fan motors
  • Receiver inlet/outlet valves and safety pressure relief valve
  • Replaceable liquid line drier & sight glass
  • Anti-short cycle time delay relay
  • Oil failure control (non-electronic)
  • Separate HP and LP compressor controls.
  • Part-winding start on all 30 HP and up, operating on 208/230V-3Ph.
  • Lock out relay.
  • Sub-cooling circuit on medium and low temperature units.
  • Electronic liquid injection on L8 units.
