BM – Medium Outdoor Air Cooled Condensing Units

Certification:

Features:

• 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.
