Description
HEACOTEX HTM Self-Regulating Heating Cable
HEACOTEX HTM is a self-regulating parallel heating cable (heating tape) that automatically varies its power output in response to changes in pipe temperature. It provides safe, reliable heat tracing for freeze protection and temperature maintenance of pipes, valves and flanges — particularly small-diameter plastic or metal pipes and instrument tubing in residential and light-commercial installations.
HTM never overheats or burns out even when wrapped over itself (overlapped). With an optional outer jacket the cable is resistant to watery and inorganic chemicals and is protected against abrasion and impact damage. HTM is also suitable for use in explosion-hazardous areas up to a maximum admissible work-piece temperature of +65°C, and the termination, power-connection, splice, tee and end-seal kits reduce installation time and require no special skills or tools.
Features
- Self-regulating — power output adjusts to pipe temperature automatically
- Energy efficient — in many applications a thermostat may not be required
- Cut-to-length on site (up to the maximum circuit length); no wasted cable
- Lower installed cost than steam tracing, less maintenance, less downtime
- Safe to overlap — no hot spots or burnout
- Suitable for non-hazardous, hazardous and corrosive environments
- CE and EAC approved

Application
Freeze protection and temperature maintenance of small-diameter plastic or metal pipes, valves, flanges and instrument tubing in residential, light-commercial and similar applications. Suitable for use in inexplosion-hazardous areas up to +65°C maximally admissible work-piece temperature.
Maximum circuit length depends on the start-up temperature and circuit-breaker size. Contact Heacotex with your circuit details for the right variant and accessory list.
