GENERAL FEATURES
Main components of the unit
1 . Air purge valve . Remaining air in the water circuit will be auto-
matically removed via the air purge valve.
3.Expansion vessel
(5 L)
4.Pressure Sensor
5.Refrigerant gas connection
7.Refrigerant liquid connection
8.Manometer.
The manometer provides a water pressure rea-
dout of the water circuit
9.Flow switch. The flow switch checks the flow in the water
circuit and protects the heat exchanger against freezing and the
pump against damage
10.Pump.
The pump circulates the water in the water circuit.
11.Heat exchanger.
The manometer provides a water pressure
readout of the water circuit
12.WATER OUTLET CONNECTION
12.1 Air purge valve
13.Pressure relief valve.
The pressure relief valve prevents
excessive water pressure in the water circuit by opening 3 bar
and discharges water.
14.WATER INLET CONNECTION
14.1 Drain valve
15.Electrical heating tape
(15.1-15.3)
- Temperature probes.
Four temperature probes determine the
water and refrigerant temperatures at various points in the water
circuit.

■
REFRIGERANT CIRCUIT : contained in a compartment protected from the air flow to simplify the maintenance operations, is equipped with DC
inverter motor driven compressor twin rotary type to ensure greater dynamic balancing and reduce vibrations. It is placed on vibration-damping rubber
supports and wrapped by a double layer of sound-absorbing material to reduce the noise. Furthermore, the compressor is equipped with crankcase
oil heater. The circuit is equipped with stainless steel brazed plates heat exchanger complete with antifreeze heater, bi-flow electronic expansion valve,
4-way valve, axial fans with brushless DC motor complete with safety protection grilles, finned coil made of copper tubes and aluminium fins. The circuit
is controlled by means of temperature probes and pressure transducers and protected by high and low pressure switches.
■ HYDRAULIC CIRCUIT: contained in a compartment protected from the air flow to simplify the maintenance operations, is equipped with electronic
circulator (brushless DC motor), water flow switch, automatic air vent, water manometer, expansion vessel, safety valve, Y water filter (supplied with
the unit but not installed) . The plate heat exchanger and all the hydraulic pipes are thermally insulated to avoid the formation of condensation and
reduce heat loss .
