Description

The most proven and reliable range of HEW-THERM Polymer Insulated (PI) series heating systems is the industry-preferred solution when circuit lengths exceed the ratings of parallel heating cables and the number of power supply points is a constraint. Operating to voltages up to 750 V, Pyrotenax are series resistance heating cables which can provide.

• Temperature maintenance up to 200°C;
• Exposure temperatures up to 300°C;
• Circuit lengths from a few metres to approximately 5 kilometres.

The stranded high temperature conductor is nickel plated to ensure a long life at elevated temperatures in corrosive environments. It is electrically isolated using an innovative sandwich construction of selected high-temperature fluoropolymers. A braid of nickel plated copper strands provides extra mechanical protection as well as a low Ohmic resistance earth path. A final PTFE jacket ensures optimum chemical resistance and highest temperature withstand capabilities.
