DESCRIPTION OF STANDARD UNIT
The air-cooled chillers with axial-fl ow fans operate with
refrigerant R410A and are suitable for installation out-
doors.
The units satisfy the essential requirements of directi-
ves 98/37/EC, 73/23/EEC, 89/326/EEC, 97/23/EEC and
subsequent amendments.
They are factory tested and on site installation is limited
to water and electrical connections.
STRUCTURE
Panels and base are made from galvanised steel plate
painted with epoxy powder to ensure total resistance to
atmospheric agents.
COMPRESSORS
Hermetic rotary scroll compressor with thermal cut-out.
CONDENSING COILS
Made from copper tubes and aluminium fi ns with a large
exchange surface.
EVAPORATOR
AISI 316 stainless steel plate type evaporator complete
with differential pressure switch. Casing lined with anti-
condensate closed cell neoprene cladding.
PUMPS
Multistage centrifugal pump with stainless steel hydraulic
assembly and corrosion prevention device to prolong the
working life of the pump. Over-sized watertight bearings
with gasket ring resistant to thermal expansion eliminate
the problem of seizure.
PUMP ASSEMBLY
Pump assembly with expansion tank, safety valve, ma-
nual fi lling assembly, pressure gauge and pump.
