Why do enclosures need heaters?

Under certain climatic conditions, condensation can built up and shorten the life expectancy of the electrical components housed in an enclosure, by causing their premature aging and failures. In response, heat is necessary to provide frost protection and avoid temperature drops by keeping the environment inside the enclosure several degrees above the ambient air.

How can condensation be prevented?

Fandis North America offers a vast range of heaters from 5 to 350W to safeguard equipment from condensation. When used with a thermostat and hygrostat they regulate the internal temperature for trouble free operations within the control cabinet.

Fandis H series: free-tool installation heaters

The Fandis H series of heaters has been designed also for free-tool installation and safe operation. These heaters use a quick connection terminals (cage clamp) and snap-on mounting on DIN rail, which simplifies the assembly time.

Heaters with plastic or metal housing

We offer versions with either metal or plastic housings. The plastic housing offers a lower surface temperature, minimizing injuries in case of accidental contact. In addition to this, we also offer a lot of different products to safeguard equipment from condensation , like Hygrostats, Heaters with fan, Cooling units, and more…

Heaters with cable

Heaters use a 3x20 AWG cable of 500mm length with FEP insulation and external silicone rubber jacket. This line starts at a heating power of 5W and covers the output up to 150W.

Heaters with terminal block

Heaters are equipped with screwless terminals for fast connection. This clamping solution allows you to reduce wiring time and assures an optimum connection over the entire service life. Heating power 45W-150W.

Heaters with fan

The version with built-in axial fan provides a forced air circulation to guarantee an even heat distribution inside enclosure or control cabinet. These ventilated heaters generate a thermal output ranging from 200W to 350W.


Thermostat

NC Thermostat controls the heater and turns it on when the internal temperature falls below a set point. In doing so, it keeps the temperature warm enough to prevent moisture building up on the electronic components.

Hygrostats

Hygrostats monitor the humidity levels within an enclosure and trigger the heater to stop the temperature going below the dew point. The advantage of using a hygrostat is the reduced energy consumption. The advantage of using this regulator is a considerable amount of energy saving.

Cooling unit

Electrical components can be protected by temperature swings between warm daytime and chill nighttime combining a compressor air conditioner with a heater.
