Constant Wattage Heating Cables

We have been producing constant power heating cables for over 40 years. We produced the world's first parallel resistance cut-to-length heating cable in 1978. Constant Wattage heating cables, as their name suggests, are designed to deliver the same power output irrespective of pipe temperature.

Our PowerHeat (AHT) is a unique patented, high power, high temperature constant wattage cable. It has an aluminium outer jacket giving it a very high mechanical strength. It has a maximum temperature of 500°C (932°F) makes it the highest temperature rated cut-to-length heating cable in the world!
