|Range||Pentair Raychem XPI-NH Heating Cable|
XPI-NH is a polymer insulated (PI) series heating cable, for use in non-hazardous areas. It has been designed for use in freeze protection and temperature maintenance applications of pipes, tanks and other equipment. XPI-NH offers an economical solution for a wide variety of heat-tracing applications in non-hazardous areas, in particular for pipe lengths beyond the maximum circuit lengths of parallel heating cables.
The selection of PTFE for the inner and outer insulation makes XPI-NH a safe and reliable product. It provides highest chemical withstand and good mechanical strength, in particular at elevated temperatures.
XPI-NH heating cables can be used for temperatures up to 260°C. The heating cable is easy to install and has printed meter-marks. Pentair Thermal Management offers XPI-NH heating cables in a very wide range of resistances, starting from 0.8 Ω/km up to 8000 Ω/km as well as a complete range of components for connection and splicing of the cables.

We make every effort in answering your questions. Below is a list of those questions we are frequently asked. Click on a question to expand its answer.
Self limiting / self regulating heating tape adjusts heat output to equal the heat loss from the pipe work. As pipe temperature falls the electrical conductivity of the semi-conductive core increas...
Yes, utilising our in-house design facilities, we can design your complete trace heating requirement.
Yes, when using trace heating on plastic pipes ensure that ATE- 180 aluminium tape is used to help disperse the heat around the pipe.
Yes, thermal insulation is required on all heat trace applications. Without insulation, surface heat losses can increase approximately 4-5 times.
Most applications can simply be straight traced, reducing costs of materials and installation time without compromising on operational requirements.
If the surface area of the pump is substantially greater than that of the adjoining pipework then extra heating cable may need to be considered (depending on wattage of cable installed). Pumps and ...
Generally, no maintenance of our trace heating systems is required but it is recommended that the system is checked for operational and electrical integrity periodically or prior to the winter or p...
System checks depend on the system installed, constant wattage systems can be fully checked for insulation resistance and continuity. Self regulating systems can only be checked for insulation resi...
This is used for a pipe freeze protection application. Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels. Trace heat...
