Heating Cables

Thermon TESH heat tracing cables are series resistance cables which provide a constant wattage. The cables are ideal for those applications requiring longer circuit lengths which cannot be achieved using parallel or self regulating trace heating cables – with IECEx and ATEX Certification Thermon TESH trace heating cables are suitable for Zone 1 and Zone 2 hazardous areas.

TESH cables have a maximum circuit length of up to 4455m and can also be exposed to temperatures of up to 260ºC ensuring suitability where steam purging occurs.

Thermon video providing an overview of best practices for installing heat trace cables to both industrial and hazardous area location pipework. Video covers heat trace cable selection, testing, inspection and pipework preparation prior to installing cables to pipes, valves, flanges and un-insulated pipe supports.

Thermon Electric Heat Tracing System Using tesh Heating Cables

A complete electric heat tracing system will typically include the following components:

1 Trace Heating Cables – depending on the application and system requirements heat trace cables are available in the following technologies: i) Series Constant Wattage ii) Parallel Constant Wattage iii) Power-Limiting iv) Self-regulating type cables.
2. Power Connection Kit
3. RTD Sensor or Control Thermostat
4. In-line/T-splice Kit (permits two or three heat trace cables to be spliced together)
5. Cable End Termination
6. Fixing Tape (to attach heater cables to pipework)
7. “Electric Heat Tracing” Label (peel-and-stick type self-adhesive warning labels)
8. Thermal Insulation

1. Heating conductor

2. Fluoropolymer dielectric insulation

3. Glassceramic tape

4. Nickel-plated copper braid (BN)

5. Fluoropolymer overjacket

Thermon TESH ensures that a consistent power output is achieved along the full circuit length of heating cable with no voltage drops making it ideal for long line heating applications. Additionally it can be used with supply voltages up to 750VAC. The heat tracing cable is part of the Thermon Industrial heating range and is ideal for manufacturing factories, plant rooms, distilleries, pharmaceutical laboratories and many more.
