Frost protection heat tape MTR, self-limiting, 25W/ metre at 10°C

Frost protection heat tape is an industrial, self-regulating heating cable that can be used as frost protection or for temperature control to 85 °C in pipes or vehicles. Heat loss depends
on cable diameter, ambient temperature, as well as the respective fluid. It’s recommended to attach additional insulation. Using a temperature controller reduces energy consumption.

Applications:
• Cold water pipes
• Drains
• Sprinkler systems
• Oil pipes

• For larger heat losses
• Heating circuit length max. at 16 A: 88 m
• Colour: Grey
• Dimensions: 13 x 6.8 mm

Electrical heat tracings don’t just guarantee frost-free operation, but also a constant cable and container temperature (operating temperature). The self-regulating cables consist of to metal wires guided in parallel, encapsulated in a semi-conductor relay PTC. When electric current is transported through the semi-conductor polymer to the other copper wire, a closed circuit is created. The polymer is heated by the current, whereby the resistance value rises. When the temperature of this conducting core rises, electrical resistance decreases and therefore the temperature does as well. This process takes place at every point along the cable. Therefore, energy efficiency is guaranteed, and overheating or combustion due to overloading is avoided.
