4. 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.

Air cooled 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.

Hydraulic module:

It is fully integrated and equipped with key hydraulic components such as Coaxial heat exchanger (applied for
AU082) and tubes in shell heater exchanger (applied for AU112/162). 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.
