Cooling units for electrical switchboards
● Respect for the environment by using environmentally friendly gas R134a.
● Cooling powers of 2500 W and 4000 W.
General characteristics
● The temperature setting can be adjusted from +20 to +50 ºC.
● They are equipped as standard with an automatically reset pressure gauge and a
switching thermostat which, when it detects a value greater than the safe pressure
value, stops the compressor and the external fan.
● The internal and external air circuits are independent. A protection rating of IP 54
is guaranteed between the outside and the inside of the enclosure.
● The fan of the internal circuit permanently guarantees prevention against hot
spots as well as improved thermal dissipation inside the enclosure.
● The devices are equipped with switches for reporting an alarm.
● Option of partial-flush mounting.
