Chemelex / Raychem XPI
Heating cables and assemblies · Process temperature maintenance
XPI is a polymer-insulated series resistance cable considered for duties including longer industrial circuits. Pro Therm calculates heated length and resistance together with the supply and reviews how cold connections fit into the plant.
