The surface of the heating cable must not exceed the maximum temperature of the constructional materials or the Termperature Classification if installed in a hazardous area. This is ensured by limiting the pipe or workpiece temperature to a safe level either by design calculation or by means of temperatue control devises.
PowerHeat (PHT)
| 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. | |  Fluoropolymer Outer Jacket |
