USER MANUAL
Control and
monitoring devices
Measure the temperature, pressure and conductivity of
the coolant. A solution based on a double-sensor
configuration is available as an option, to guarantee full
operation in case of single sensor failure.
Water pump
Circulates the coolant through the internal cooling circuit.
The standard solution is based on redundant pumps (one
of the two pumps is always on standby and starts
automatically if the running pump fails).
An alternative solution based on one pump is
also available.
Water-to-water
heat exchanger
Transfers the heat from the internal cooling circuit to the
external cooling circuit.
Expansion vessel
Used for pressure compensations
Ion exchange vessel The ion exchange vessel in the water treatment circuit
deionizes the coolant of the internal cooling circuit and
maintains the conductivity.
3-way valve
The three-way valve controls the flow of the external
cooling liquid through the water-to-water
heat exchanger.
