outdoors.The compressor circuits are completely

independent refrigerant circuits. Compressor unloaders
are solenoid actuated and oil pressure operated. Each
refrigerant circuit is provided with filter, sight glass,
electronic expansion valve, and charging valves.The
shell-and-tube type evaporator is manufactured in
accordance with ASME standards or other international
codes. Each evaporator is fully insulated and is equipped
with water drain and vent connections. Packaged units
