AHT | constant power 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

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