  • Superior Coil Protection – A stamped decorative metal coil guard completely protects coil from debris and other large damaging material while a polymer mesh further protects the coil against smaller particles.
  • Isolated Compressor Compartment – A molded composite bulkhead isolates the compressor from the rest of the unit reducing sound and vibration.
  • Protected Compressors – Each compressor is protected against high and low pressure as well as excessive temperature. This is accomplished by the simultaneous operation of high pressure relief valve and temperature sensors.
  • Environmentally Friendly Refrigerant – Next generation refrigerant R-410A delivers environmentally friendly performance with zero ozone depletion.
  • Durable Finish – Automotive quality finish provides the ultimate protection from harmful U.V. rays and rust creep ensuring long-lasting high quality appearance. A powder-paint topcoat is applied over a baked-on primer.
  • Lower Installed Cost – Designed to provide enhanced installability by featuring a slide-down control compartment and angled service valves to reduce overall installation time and cost.
  • Low Operating Sound Levels – A fan design boasting technology adapted from aeronautic and defense engineering provides for whisper quiet operation by allowing airflow to flow smoothly and efficiently across the fan tips.
  • Filter-Drier – A factory installed, solid core liquid line filter/drier filters harmful debris and moisture from the system.
  • Easy Service Access – A full end, full service, access panel with handle makes for easy entry to internal components.
  • Long Lasting Operation – Strong and durable composite base pan provides added strength while resisting rust and corrosion as well as reducing sound vibration.
  • Complete System Control – These heat pumps utilize the unique microprocessor defrost control system to provide optimal comfort as well as monitor the overall system for reliable operation.
