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 (AHT)
| PowerHeat (AHT) is a unique patented, high power, high temperature, high mechanical strength constant wattage heating cable that can be used for freeze protection and temperature maintainance of pipework and vessels. It has a maximum temperature of 425°C (797°F) makes it the highest temperature rated cut-to-length heating cable in the world!
PowerHeat (AHT) has an aluminium outer jacket giving it the highest mechanical strength of any cut-to-length heating cable in the world!
PowerHeat (AHT) can be cut-to-length at site to match exact piping lengths without any complicated design considerations. PowerHeat (AHT) can, in most cases, 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 (AHT) is approved for use in non-hazardous, and hazardous areas to world wide standards. PowerHeat (AHT) is jacketted in a continuous aluminium extrusion for maximum mechanical strength. The aluminium jacket allows the cable to be formed around valves, pumps and instruments.
The installation of PowerHeat (AHT) 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. | |
