Features

  • Energy efficient, automatically varies its power output in response to pipe temperature changes
  • Easy to install, can be cut to any length (up to max. circuit length) required on site with no wasted cable.
  • Lower installed cost than steam tracing, less maintenance expense and less downtime.
  • No overheat or burnout even when wrapped over itself (overlapped).
  • Suitable for use in non-hazardous, hazardous and corrosive environments.
  • Velox power connection, splice, tee and end seal kit will reduce the installation time.

Description

HTP increasing or decreasing the heat output in a self-regulating way depending on the change of the ambient temperature, so a thermostat may not necessary in some applications and it will never overheat or burnout even when wrapped over itself (overlapped). With optional outerjacket, the heating cable is resistant to watery and inorganic chemicals and protect against abrasion and
impact damage . HTP is suitable for use in explosion-hazardous areas up to a maximally admissible work-piece temperature of +110℃.

Värmekabelteknik provide termination, power connection, splice, tee and end seal kit will reduce installation time and require no speical skills or tools.

Appliance

HTP is UL listed self-regulating parallel heating cable designed for pipe heat tracing in industrial applications, it is configured for use in hazardous and non-hazardous locations, including areas where corrosives may be present. It can provide process-temperature maintenance up to 110 ° C (230 ° F) and it can also be used for frost protection of large pipes and freeze protection in systems having high heat loss.
