Unit casing is constructed of heavy gauge, galvanized steel and painted with a weather-resistant
powder paint finish. The corner panels are prepainted. All panels are subjected to our 1,000 hour
salt spray test.
Refrigerant Controls
Refrigeration system controls include condenser fan, compressor contactor and low and high
pressure switches. A factory supplied, field installed liquid line drier is standard.
Compressor
The compressor features internal over temperature and pressure protection. Other features
include: Centrifugal oil pump and low vibration and noise.
Condenser Coil
The outdoor coil provides low airflow resistance and efficient heat transfer. The coil is protected
on all four sides by louvered panels.
Low Ambient Cooling
As manufactured, this system has a cooling capacity to 55°F. The addition of an evaporator
defrost control permits operation to 40°F. The addition of an evaporator defrost control with TXV
