Installation 65
2. Description of Standard Unit
These air cooled reverse-cycle chillers with axial-flow fans operate with refrigerant fluid and are suitable for
outdoor installation.
They are factory tested and on site installation is limited to water and electrical connections.
Structure:
Panels and base are made from galvanized steel plate painted with epoxy powder to ensure total resistance
to atmospheric agents. Condensate collection pan as standard.
Compressors:
Scroll compressor with crankcase heater and thermal cut-out.
Evaporator:
AISI 316 stainless steel plate type evaporator complete with electric heater and differential pressure switch.
Casing lined with anti-condensate closed cell neoprene cladding.
Pump:
The units feature a pump with the moving parts in contact with the water made from corrosion resistant
materials, extra wear ring on the impeller, built-in capacitor for high starting torque and automatic venting of
impeller chamber.
Pump assembly:
Pump assembly with expansion tank, safety valve, auto water replenishing assembly, pressure gauge and
pump.
Condensing coil:
Made from copper tubes and high surface area aluminum fins. Condensing coil protection grills as standard.
Fans:
Axial-flow fans. Six-pole electric motor with built-in thermal cut-out. Housed in aerodynamic tubes with
accident prevention grill. Device for operation with low outside air temperatures: continuous fan rotation
speed control via condensing temperatures transducer.
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 “HSW7” control panel.
