• Designed for use with R22, R404A, R507 and R407C.
• 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 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.
• 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, (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.
• Units are available with energy efficient Thermosaver™ hot gas defrost option.
• Units are environmently friendly operating on less power and refrigerant charge.
