Product Features

              ATEX - European Hazardous Area Approval

PowerHeat (PHT) is a high power, high temperature constant wattage heating cable that can be used for freeze protection and temperature maintainance of pipework and vessels. if has a maximum withstand temperature of 285°C (545°F).

PowerHeat (PHT) can be cut-to-length at site to match exact piping lengths  without any complicated design considerations.  PowerHeat (PHT) can be used to replace MI cables.  Series resistance Mi circuits must be specifically designed for a particular pipe length and cannot be modified to suit site changes.

PowerHeat (PHT) is approved for use in non-hazardous, and hazardous areas to world wide standards.

The installation of PowerHeat (PHT) is quick and simple and requires no special skills or tools. Termination, splicing and power connection components are all provided in convenient kits. See Product, Application and Documentation Links below.
