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 ºC.
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.
●
The temperature inside the enclosure does not
depend on the external temperature.
●
The internal and external air circuits are
independent.
●
Security device against possible leaks.
●
Even temperature inside the enclosure.
●
High protection rating: IP 54.
●
Use of an environmentally friendly gas.
●
Small dimensions.
●
Equipped with a PTC-type heating system, which
stabilises the surface temperature of the aluminium
profile.
●
Available in two versions: insulated with low surface
temperature or in aluminium when the surface
temperature is limited to 75 ºC.
●
The fan-equipped resistances guarantee an even
temperature inside the enclosure.
●
A cold-water supply source is required.
●
Specific pumping installation.
●
Installation of a drain is recommended.
●
Maintenance required: filter replacement.
