  • Can be cut-to-length with minimal wastage.
  • Suitable for high process temperature maintenance applications up to +200°C.
  • Full range of terminations, controls, accessories and approvals available.
  • Will not overheat, even when overlapped.
  • Available for 220=277V AC (110V=120V AC upon request)


Quintherm ILH is a high temperature industrial/commercial grade self-regulating heating tape that can be used for high process temperature maintenance of pipework or vessels in the pharmaceutical [&] chemical or construction industries up to 225°C (switched off) which may be subject to steam cleaning. It can be cut-to-length on site to match exact pipe lengths without any complicated design considerations.

ILH is approved for use in non-hazardous, hazardous or corrosive environments to world-wide standards.

Its self-regulating characteristics improve safety and reliability. ILH will not overheat or burnout, even if overlapped upon itself. Its power output is automatically self-regulated in response to pipe or heated surface temperature. This ensures safety and reliability.

Installation of Quintherm ILH is quick and easy, requiring no special tools or skills. Terminations, inline splicing and power connection components are all available in convenient termination kits.

Available Options

ILH../Qx - Base heating tape without any braiding or outerjacket (only for non-Ex applications) (available upon special request)
