AHT | constant wattage heating cable (Ex) up to +425 °C

AHT is a unique patented, high power, high temperature, high mechanical strength constant wattage heating cable used for freeze protection and temperature maintenance of pipework and vessels. It has a maximum temperature of +425 °C makes it the highest temperature-rated cut-to-length heating cable in the world.

General details

AHT2 is a parallel circuit, mineral insulated, cut-to-length, constant power heating cable of 10 W/m, 15 W/m, 30 W/m, 50 W/m, 70 W/m, 100 W/m and 150 W/m output. It is designed for the heating process of industrial pipes with high temperatures. Suitable for use in both, safe and hazardous (Ex) areas, can withstand the temperature of up to +425 °C (when switched OFF).
AHT2 is a flexible and mechanically robust cable with an extruded aluminium overjacket which retains some flexibility. It is cut-to-length and can be easily connected to a power cable with the support of junction boxes or connectors. Available in 100-150 m reel.

Installation: the cable is used for high-temperature maintenance of industrial pipelines.
