Door frames and seals in refrigerated and freezer areas are frequently exposed to significant temperature fluctuations. When humidity condenses and freezes at low temperatures, door seals can freeze, making doors difficult to operate or even damaging them.

Electric door frame heaters effectively prevent this problem. The heating systems are installed directly in or on the door frame and maintain the seals and adjacent door surfaces at a constant temperature. This ensures the door remains easy to open and close and fully functional at all times – regardless of the ambient temperature.

The heaters are specifically tailored to the door size, installation situation, and the climatic conditions of the cold storage room. Targeted heat distribution prevents ice formation, protects the seals, and extends the door's lifespan.
