Performance in Extreme Conditions
- Hot gas bypass for cooling operation at low ambient temperatures, down to 45ºF / 7ºC without freezing
- Hermetically sealed reciprocating compressor is cooled during the refrigeration cycle, which allows the unit to tolerate higher outdoor temperatures up to 130ºF (55ºC)
Coated Coils for Corrosion Resistance
ElectroFin® 5-stage, immersion ecoat process, or Diamonblue Advanced Corrosion Protection® on 100% of metallic surfaces on the outdoor coil provides outstanding corrosion resistance protection and extends the life of the unit, especially in coastal or corrosive environments.
