TRENTON TV – Large Outdoor Air Cooled Condensing Units

• Units are _CUL_US Listed.

• Designed for use with R22, R404A and R507.

• Energy efficient compressors with POE or mineral oil.

• Several compressor options to choose from: Copeland and Bitzer

• Single, Dual and parallel-piped (optional) compressor configurations available.

• Thermospan^TM 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 air conditioning and H2 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 Thermosaver^TM hot gas defrost option.

• Units are environmentally friendly operating on less power and refrigerant charge.
