3. Description of main components
Structure
Panels and base are made from galvanized steel plate painted with epoxy power to ensure total resistance
to atmospheric pollution, condensate collection pan as standard.
Condenser coils:
The coils are made from high performance and seamless copper tuber and high surface area aluminum fins
to ensure optimum heat exchange capability. Condenser coil protection grill is standard.
Fan motor:
To achieve high efficiency heat exchange, the unit is equipment with the high performance axial-flow fans.
The fan is driven directly by weather proof motor to ensure reliable operation, the fan motor is six-pole
electric motor with built-in thermal cut-out.
Evaporator:
The heat exchanger is made of AISI 316 stainless steel to ensure high heat exchange efficiency, complete
with electric heater and differential pressure switch. The complete heat exchanger is insulated with thermal
insulation closed cell rubber foam to give optimum thermal insulation.
Hydraulic module:
It is fully integrated and equipped with key hydraulic components such as expansion tank, plate type of
heat-exchanger, water circulating pump.
The water pressure difference switch is provided in the units to protect against damage to the water pump.
Power and control electrical panel
Power and control electrical panel constructed in accordance with IEC 204-1/EN60335-2-40, complete with
compressor contactor, control via control panel.
