• Compatible with Low GWP Refrigerants
• Units are CULUS Listed.
• Designed for use with various popular refrigerants.
• Energy efficient compressors with POE oil. 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 reduces 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 H8 models) increases overall system efficiency and provides dependable compressor operation.
