Constant Power Heating Cables – PowerHeat (AHT)
PowerHeat (AHT) is a high-power, high-temperature, and mechanically robust constant power heating cable.
It is designed for freeze protection and temperature maintenance of pipes and tanks. With a maximum operating temperature of 500 °C, it is the world’s most temperature-resistant cut-to-length heating cable.
Its aluminum outer jacket provides the highest mechanical strength among all constant power heating cables available on the market.
PowerHeat (AHT) heating cable is certified for use in both non-hazardous and hazardous areas according to international standards. It holds CNEX, DNV, EAC, ATEX, IEC, IECEx certifications and complies with European Union (CE) requirements.
Thanks to its aluminum jacket, the cable can be shaped around valves, pumps, and instruments.
