Heating cables
The outdoor heating cables are designed for frost protection and melting ice and snow. They may be installed with no covering on top of roof constructions, into special glue under tiles for ground constructions, or under insulation layer for pipes.
With heating cables the areas, pipes and equipment are kept free from ice and snow at all times. It allows you to avoid heavy salting, snow shoveling, or frost damages.
The range of heating cables’ linear output for ground applications is usually 10–30 W/m (depending on application).
