Air-air exchangers
Air-air exchangers are devices that combine efficiency and simplicity. The hot air
flows of the enclosure and the cold of the surrounding environment, created by two
fans, circulate on either side of hermetic separation walls, preventing the penetration
of dust or moisture in the enclosure. The hot air from the switchboard reheats these
walls, which in turn are cooled by the fresh air from outside. The transfer always
takes place from the hotter side to the cooler side. This is why these devices can
only be used if the ambient temperature is at least 5°C lower than the desired
temperature inside the enclosure.
The aluminium exchange cassette forms the core of the system. This element can
be cleaned easily by simply removing it. In addition, the permanent operation of
the internal fan prevents the appearance of hot spots in the electrical switchboard.
The temperature regulation system integrated in the unit turns the external circuit
fan on and off.
Air-water exchangers
Air-water exchangers operate on the same principle as air-air exchangers.
Fresh air from the outside is replaced with cold water supplied by a network installed
on the industrial site. This change of fluid makes it possible to evacuate much larger
amounts of heat and, possibly, to reduce the temperature in the enclosure below
the temperature of the ambient air.
Temperature control in the enclosure is carried out by modulating the water flow.
The water circuit is protected by a shut-off device: your electrical installation is safe.
Cooling units
Cooling units can be used in the harshest environments, where the temperature
can reach 55°C. These devices are especially recommended when the desired
temperature inside the enclosure must be lower than the ambient temperature
or when a large amount of heat needs to be evacuated. As in the case of the
exchangers, they do not affect the IP of the switchboard.
The filter, placed at the inlet of the external air circuit, allows it to operate even when
the ambient air is charged with dust or oil particles. Easily replaceable and quite
inexpensive, this device guarantees the efficiency of the device throughout its
service life. These devices control the temperature inside the enclosure and include
an alarm function for signalling operational anomalies.
