Heaters & Thermostats

Heaters, Thermostats & Hygrostats are geared toward the protection of electronic equipment for customers in many industries and applications, such as:
- CCTV Surveillance Cameras
- Power Generation including Backup Power
- Wind and Solar Power Systems
- Electrical and Electronic Control Systems
- Wireless and Broadband Telecommunications Systems
- Automatic Teller Machines (ATMs)
- DOT and Traffic Control Systems
- Parking Control Systems
- Information Kiosks
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 precisely where the function of our control cabinet heaters (radiant heaters and fan heaters) begins to protect. We offer a wide variety of performance classes of FLH control cabinet heaters which are complemented by thermostats and hygrostats from the FLZ series. As a team, they ensure that the temperature inside the control cabinet is always correct and that the formation of condensation is prevented. The control of filterfans by thermostats from the FLZ series represents an intelligent use of filterfans for control cabinet air cooling to suit individual needs. It increases energy efficiency, reduces CO2 emissions and reduces filter maintenance levels. Accordingly the combination with thermostats and hygrostats from the FLZ series offers a better environmental balance through higher energy efficiency. It also 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

Radiant & Fan Heaters Radiant heaters are compact and cover a wide operating range. They are used in combination with a thermostat or hygrostat, predominantly for the avoidance of excessively low temperatures or excessively high humidity in the control cabinet and help to avoid the formation of corrosion. Mini-heaters and surface temperature-limited heaters are particularly suitable for use in small housings or for the heating of isolated spots in sensitive areas.
FLH Fan Heaters & FLH -TF Fan Heaters with Thermostat
These radiant heater products are more ideal for use in larger electrical enclosures. They have an integrated fan that assists the natural convection and provides fast and even distribution of the heat. Fan heaters with thermostats are 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 & Hygrostats
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, besides temperature control, 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 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. A new electronic combination device unites the thermostat and hygrostat in one housing.
