Features

HTP is an industrial grade self-regulating heating tape that can be used for freeze protection or temperature maintenance of industrial pipelines and vessels.

It can be cut to length on site and exact piping length can be matched without any complicated design considerations.

HTP is certified for use in safe and explosion hazardous environments against international standards as well as GOST R 60079 standards.

Its self-regulating characteristics improve safety and reliability. HTP will not overheat or burnout even when overlapped. The heat output adjusts automatically subject to temperature change.

The installation of HTP heating tape is quick and simple and requires no special skills or tools. Termination, splicing and power connection components are all provided in kits.

Options

HTP..BT
Thermoplastic elastomer outer jacket over tinned copper braid ensures additional protection.
HTP..BP
Fluoroplastic outer jacket over tinned copper braid provides protection where corrosive chemical solutions or vapors may present.

For use with type C circuit breakers according to GOST R 50345- 2010 (IEC 60898-1:2003)

* A current step takes place (starting current) at the moment of turning on the heating section. The current value stabilizes within 5 minutes after start-up. Maximum starting current can be 5-6 times higher than the rated current value of the circuit breaker.
