Refrigerant Circuit: The circuit includes: liquid line
shut-off valve, charge connection, liquid line sight glass, filter dryer,
electronic expansion valve, safety valve, pressure transducers to relay
information on high and low pressure values and relative condensing and
evaporating temperatures for display on the controller, high and low pressure
switches.
Evaporator: Brazed plate with antifreeze protection and
mechanical flow switch.
Condenser: Composed of high efficiency coils in “V”
execution.
Fans: Axial fan directly coupled to 6-pole motors, thermal
overload protection and safety guard.
Electrical Panel: With main switch, power and control
circuit protection and fans. Microprocessor control with function display.
Testing: Units are factory-tested and shipped complete with
refrigerant charge and oil.
