Constant Wattage Heaters

We have been producing constant power heating cables for over 30 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 425°F (797°F) makes it the highest temperature rated cut-to-length heating cable in the world!

These cables can be used for a wide variety of applications including freeze protection of pipework and vessels and process temperature maintenance.  See Applications page for more detailed information, 

We can produce constant power heating cables within the following ranges:

• 12 - 1000 Volts
• Up to 425°C (797°F) withstand temperature
• Up to 200 W/m of output

We normally supply heating cables with a braid and outer jacket but cables can also be supplied with just a braid.  Please ask or see datasheets for more information.
