  • Selection by hand wheel valve.

Reverse Cycle Operation:

  • Evaporator pressure regulating valve for dual temperature operation.
  • High pressure switch.
  • Low pressure switch.
  • Low pressure gauge.
  • High pressure gauge.
  • Sight glasses.
  • Check Valves to control direction of refrigerant flow.
  • Hand valves

By using an evaporator pressure regulator, the unit operates two evaporators on a single compressor, demonstrating both refrigeration and air conditioning concepts. The condensing unit has an air-cooled condenser, a liquid receiver, and a high starting torque motor with an integrated winding protector. An automated condenser pressure regulator is a feature of a water-cooled condenser. A copper tube coil block with fins is present in both the static and forced air evaporators. Hand valves can be used to select the Flow Controls. Included in this group are the automatic expansion valve, the internal and external equalized thermostatic expansion valves, and the capillary tube. A solenoid reversing valve is used to operate in reverse cycle. The two evaporators may run at various pressures and temperatures , which allows by an evaporator pressure regulator. High pressure switch, low pressure switch, low pressure gauge, and high pressure gauge are among the controls. On/off switches for the evaporator and condenser, a reverse cycle switch, an overload, and an earth leakage circuit breaker for protection against earth leakage are all located in an electrical control box that is mounted on the front panel.
