Self-adjusting expansion and solenoid valves

The expansion valve and solenoid valve adjust refrigerant circulation as internal temperature changes.

Blue anti-corrosion fin and coated copper tube

The cutsheet identifies these components as protecting pipes from corrosive gases and helping prolong cooling capacity.

Micro channel condenser coil

The efficient micro channel condenser coil provides a larger heat-transfer area than a fin-and-tube condenser coil, according to the cutsheet.

Energy-efficient EC motor

The unit uses an EC motor and is designed with easy-to-replace motor and fan blades.

Patented hot gas condensate system

The leak-free system uses hot gas to evaporate condensed water and incorporates corrosion-prevention technology.

Air circulation enclosure

The highly efficient enclosure is designed to release hot air outside and retard compressor temperature elevation.

Hot gas defrost

The unit specifications identify hot gas defrost.
