Air-water exchanger
Cooling
Heating
Air-water exchangers reduce the temperature
inside the enclosure by means of a water-cooled
exchange cassette.
Temperature control inside the enclosure is
performed by a thermostat which opens and
closes an electro-valve.
Air-conditioning device providing efficient cooling
of the enclosure, regardless of the outside air,
and prevention against hot spots.
The resistance heaters prevent the formation
of condensation and guarantee the ideal temperature
for the correct operation of the electronic components.
The air-water exchangers are used to evacuate
large amounts of heat. They require a cold-water
circuit with stable temperature and flow rate.
They are specially recommended in difficult,
highly polluted environments where there is
no external air circuit.
The cooling units can be used in the harshest
environments, where the temperature can
reach up to 55°C.
These devices control the temperature inside
the enclosure and include an alarm function
for signalling operational anomalies.
The resistance heaters are used to reheat the electrical
switchboard when the ambient temperature is too low
or to prevent the formation of condensation.
