The de-humidifier Delvalle is a special form of switch cabinet cooling technology. There is a fan-free cold plate in the indoor of the switch cabinet, on which the air humidity completely condenses. The resulting water droplets run off the plate, are collected in a runnel and drained out of the switch cabinet by a small tube. In order to avoid the formation of ice, the cold plate is equipped with temperature sensor, which keeps the temperature of the cold plate in the ideal range by means of the integrated regulator.
Just like our switch cabinet coolers, the switch cabinet de-humidifier is easily installed and is equipped with a temperature protection switch and an alarm relay.
The latest generation of our switch cabinet de-humidifier has, in addition to the integrated controller, a connection for a humidistat.
With variations of temperature in enclosures it comes to condensation and precipitation of humidity. Thast causes corrosion, disturbances and breakdown of electrical controls. 
3 different versions for various cases of application.
