General Description
The industrial coolers of the KPC series are fully assembled, factory inspected and tested, and suitable for fully-
automatic operation.
The industrial cooler of the KPC series consists of the refrigerant circuit, the cooling medium circulation, the transfer
station, the switch box and the remote control panel.
The refrigerant circuit includes compressor, primary side of the heat exchanger, air cooled condenser, necessary
equipment for liquid and gaseous refrigerant, safety and control device.
The cooling medium circulation includes secondary side of the heat exchanger with automatic air vent, medium heating
(electrical), circulation pump, expansion receiver, pressure relief valve, necessary equipment for cooling medium,
safety and control device.
The transfer station includes supply and return connections with shut-off valves, necessary equipment for cooling
medium, filling and draining cocks.
The refrigerant circuit and the cooling medium circulation are designed as a cooling block with built in switch box
Cooling block Type KPC 108 - L - U/S 60 Hz
air-cooled design for outdoor use
The control elements are integrated in the front of the switch box. The remote control panel includes control switch,
lamp “run” as a status massage and lamp “fault” as a general fault massage.
The temperature set on the controller is kept automatically.
The cooling medium is constantly circulated by the pump.
The process heat is being transmitted from the cooling medium to the heat exchanger (evaporator of the refrigerant
circuit) and used for refrigerant evaporating (cooling). The compressor raises the gaseous refrigerant to a higher
pressure so that the warmth can be released via the condenser to the surrounding air. Consequently good air supply
and escape are vital for the proper running of the plant.
The cooling medium supply temperature can be changed from +7 °C to +12 °C by the temperature controller in front
of switch box.
Attention!
Changes in the settings should only be made by qualified operatives.
The housing with stable welded, galvanized framework-construction, lateral cover-plates with drawer-edges made of
galvanized steel plate with ventilating nozzles worked into the top plate.
Framework-construction and top-plates are powder-coated on the inside and outside. All outer fastening screws rust-
proof, inspection-caps at the front easily removable for maintenance using casement-fastener caps.
Compressor, refrigerant and cooling medium mountings, additionally sound and rain-proofed using a galvanized cover-
plate.
Condenser axial-fans, pressure switch controlled condenser pressure dependent. Ventilators equipped with protective-
grating on the delivery side of the pump.
Laterally mounted condenser heat exchanger made of copper-aluminum with covering galvanized framework,
enameled fully in black.
