Description
HEACOTEX HTR Self-Regulating Heating Cable
HEACOTEX HTR is a low-temperature self-regulating parallel heating cable used for freeze protection and process temperature maintenance on pipes, vessels, valves and flanges. The PTC self-regulating conductive core automatically varies its heat output in response to local pipe temperature — no overheat or burnout even when the cable is overlapped over itself, and no special skills or tools required at the termination.
The HTR family covers six output ratings to match almost any low-temperature application, can be cut to length on site, and is certified for use in both ordinary and hazardous areas. Optional tinned copper braid and choice of FR thermoplastic or high-temperature fluoropolymer over-jacket gives mechanical protection and chemical resistance for harsher installations.
Features
- PTC self-regulating — heat output adjusts automatically along the cable length
- Cut-to-length on site within the maximum circuit length
- Safe to overlap — no hot spots or burnout
- Six output ratings cover most low-temperature applications
- Certified for hazardous and ordinary areas (NEPSI, IECEx, ATEX, EAC, UL, CSA, CCC, CE)
- Temperature classification T5 / T6
- IP66 / IP67 sealed construction
- Lower installed cost than steam tracing, less maintenance, less downtime

Application
Plastic or metal pipe freeze protection, flow maintenance of pipes, tanks and valves, roof and gutter de-icing, and process temperature maintenance in industrial, commercial and residential installations — including non-hazardous, hazardous and corrosive environments.
Maximum circuit length depends on the start-up temperature and the circuit-breaker size. Contact Heacotex with the start-up temperature and circuit length you need and we will recommend the right variant and breaker configuration.
