Constant Wattage Heating Cables – PowerHeat (PHT)
PowerHeat (PHT) is a high-power, high-temperature constant wattage heating cable designed for frost protection and temperature maintenance of pipes and tanks. It can withstand temperatures up to 285 °C.
This constant wattage heating cable can be cut to the desired length on site without requiring complex calculations.
It offers an alternative to mineral insulated (MI) cables, which, being series resistance circuits, must be specifically designed for a given pipe length and cannot be easily adjusted on site.
PowerHeat (PHT) cable is approved and certified ATEX, IEC, IECEx, and CE for use in both non-hazardous and hazardous areas, in compliance with international standards.
