CHILLED WATER PUMP GROUP (optional)
The pump group for the circulation of chilled water is available in
different configurations:
- one pump (type "A", "B" or "C");
- two pumps (one in stand-by);
- one pump plus reservoir tank;
- two pumps (one in stand-by) plus reservoir tank.
The pumps, with 2-pole motors (2900 rpm), are fitted with the related
connections, collectors and electrical panel (located in the main
electrical panel housing). The pump panel controls rotation of operation
between the two pumps on the basis of run time or alarms. The
electrical panel contains the run hour counter for each pump and red
LED alarm indicators.
Pump body, flange and impeller are AISI 304 stainless steel, insulation
is class F and protection is to IP55. The materials used ensure correct
pump operation with liquid temperatures from -10°C to +85°C.

FINNED COILS
In air-cooled versions the condenser consists of coils with aluminium fins and copper tubes mechanically
expanded to obtain an optimum metallic contact and maximum exchange efficiency. The coil has a very large
surface area for operation with high ambient temperatures and has an integrated super-cooling circuit.
If there are harsh conditions in the installation environment, various treatments are available for the
exchanger: pre-painted aluminium, copper-copper protection and cataforesis aluminium treatment;
cataforesis provides the best compromise between cost and performance.
