Heaters, Thermostats & Hygrostats

Additional Protection for Your Electronics

Heater

The formation of condensation is one of the biggest dangers for electrical enclosures. As long as they are working under load, their own warmth prevents water from condensing. If the process is switched off, the electronics cool down. This is where our control cabinet heaters (radiant heaters and fan heaters) provide additional protection for your electronics. 

Pfannenberg's Heaters, Thermostats and Hygrostats detect and keep ambient conditions above dew point to avoid the harmful effects of condensation on your electronics. They can be used as a standalone product or in partnership with our Filterfan® and Cooling Unit product lines.

Additionally using a thermostat or hygrostat results in greater reliability of your production process:

  • Pinpoint distribution and constant temperature in the control cabinet.
  • Reduced energy consumption and optimization of the efficiency of the heaters.
  • Additional savings on energy, materials and time.

Pfannenberg's heaters, thermostats and hygrostats expand Pfannenberg's protection to additional outdoor applications such as ATMs, Kiosks, Ticket Machines etc.

FLH_HeatersFLH Fan Heaters

Ideal for use in larger electrical enclosures, they have an integrated fan that assists the natural convection and provides fast distribution of the heat in the electrical enclosure. The fan heaters are used in combination with a thermostat or hygrostat, for the avoidance of excessively low temperatures or excessively high humidity in the electrical enclosure and also help to avoid corrosion.

The PFH-T fan heater with thermostat is designed to protect electronics from the effects of low temperatures such as corrosion, freezing or condensation, which can damage critical components within a control enclosure.

Thermostats are used as temperature controllers and, therefore, for the control of Filterfans® or electrical enclosure heaters. They are available with N.C. (normally closed) / N.O. (normally open) and changeover contacts. In combination with control cabinet heaters you can ensure that the control cabinet is 'artificially' dehumidified, in particular in outdoor applications. That means that the temperature is kept above the dew point so that no water condenses out of the air, which could lead to short circuits due to the formation of condensation.

Hygrostats_FLZ_610Hygrostats

Hygrostats switch on electrical enclosure heaters or Filterfans® when a preset relative humidity is exceeded. The relative humidity is kept above the dew point and the condensation of water on electrical components and the corrosion of unprotected sheet metal is prevented.
