4. International Standards

Heat Trace has been active in the development, maintenance and harmonisation of international trace heating standards for more than 40 years. We took a leading role in the development of the 1st trace heating standard back in the early 80's - BS6351 - Electric Surface Heating, the first British standard published in 1982, through to IEC60079/30 – a harmonised World Standard first launched in 2001.


5. Heat Trace is committed to Research & Development
NEW Products

Heat Trace has been in business since 1974, and we are the only UK company that manufactures self-regulating electrical heat tracing cables and systems. 90% of our products are exported.

Major investments in Research and Development have enabled us to become the global technical leader in our field. Heat Trace core technology is the development of electrical heating products based on semi-conductive polymers. Heat Trace‘s strategy is to maintain and extend this technological lead by the following five step approach.

  1. Heat Trace invests 15% of turnover in R&D.
  2. Heat Trace works with leading UK universities and research organisations so that new technology can be quickly transferred into the development of advanced new products.
  3. Heat Trace utilises UK and European grants for research, product development and personnel training. Heat Trace has been awarded six major grants in the last five years.
  4. Heat Trace’s objective is to launch 4 new products every year. Our newest introductions can be found here.
  5. Heat Trace protects its technology with an extensive patent portfolio. The company has been granted 11 patents, and has another 12 patent applications filed in the major global market regions.


6. Working within an ISO9001 compliant environment
iso9001 logo

Heat Trace is an ISO9001:2015 accredited company for manufacturing, system design, engineering and product development. Our first quality certification was issued on 4th October 1991 and has been updated and re-assessed over the years. This leads to a finely tuned and ideally suited quality management system for a modern, leading global manufacturer.

It is the stated quality policy of Heat Trace to satisfy the requirements of our customers. This can only be achieved by operating a comprehensive, co-ordinated quality system that assures the quality of all products, processes and services offered by the company.

This system has been re-designed and updated to meet the requirements of ISO 9001:2015 and is implemented across the whole Organisation, embracing all of the activities which impact upon our customers.

The Directors of the company are committed to ensuring that the system is effective in achieving quality and satisfying customers both now and in the future.

In September 2002 HTL Quality Systems demonstrated compliance with the ATEX Directive 94/9/EC, therefore enabling the company to sell certified products for use in Hazardous Locations and Explosive Atmospheres in Europe.

The Quality Systems were enhanced when in May 2011 HTL successfully gained the world wide IECEx Quality Assessment Report, bringing the company up to date with Quality System accreditation, at that time.

Heat Trace Quality portfolio has been further extended by the addition of the new UK QAN in October 2021, allowing Ex products to be certified and sold under the new UK Explosion proof scheme into our home market with the advent of Brexit.

We will strive to continually improve our products, processes and systems by setting quality objectives that are measurable and are reviewed.

7. Heat Trace began over 40 years ago on a foundation of innovation
PowerHeat (AHT)

Heat Trace has remained an innovative company throughout it’s history, developing a stream of unique products and processes, aimed at improvements to safety, efficiency, performance and system longevity. It’s strategy is to maintain and extend this technological lead, through significant internal investment, UK and European grant funding, and strategic partnerships with other companies and organisations, with whom we share common goals and complimentary capabilities.

Some of the major outcomes of Heat Trace’s innovative approach are:

  • Inherent Temperature Safety of HTL self-regulating products
  • Highest Power Output self-regulating cables
  • Highest Thermal Withstand self-regulating cables
  • 3-phase self-regulating heaters
  • Integrated conductors for increased cable robustness and longevity
  • Widest voltage range, from low voltages suitable for automotive, or solar-powered applications, to very high voltages for long pipelines
  • Stabilised designs with self-regulating cables to allow accurate temperature maintenance of sulphur, bitumen etc. with minimal controls
  • Aluminium jackets, especially for mechanical protection and heat dissipating properties
  • AHT- still a peerless product, the only real cut-to-length alternative to M.I cables
  • LONGLINE R - for intermediate circuit lengths between parallel resistance, self-regulating or constant power, heating cable and traditional series resistance LONGLINE heating cables

10. World’s first products

Heat Trace has remained an innovative company throughout its history, developing a stream of unique products and processes, aimed at improvements to safety, efficiency, performance and system life of heat tracing. In doing so HTL has become the Technical Leader in Heat Tracing Technology.

World’s First products developed by Heat Trace:

1978 - Heat Trace produce the world's first cut-to-length parallel resistance tracer. Heat Trace’s patented Heat Tracer cable was introduced into the market as the first cut-to-length tracer in 1978. The Heat Tracer remains to this day the most thermally efficient parallel resistance heating cable.

1982 - Heat Trace introduce 'Longline', a series resistance tracer for long pipelines. ‘Longline’ is launched for buried pipelines in New Zealand. Almost 3 decades later, after millions of metres, Heat Trace has never experienced a manufacturing related product failure. ‘Longline’, now re-invented, is the lowest cost solution for long pipeline tracing.

1998 - Heat Trace Ltd launch the world's highest temperature parallel resistance cut-to-length constant power heating cable. Heat Trace’s patented AHT mineral insulated, metal-sheathed heater that can withstand 425°C continuously and has power outputs to 200W/m. Over a decade later it still remains the world’s highest temperature parallel resistance constant power heat tracer.

2003 - Heat Trace Ltd introduces the world's highest temperature Self Regulating Heat Tracer. Heat Trace’s FSU Freezstop Ultimo has a continuous withstand temperature of 250°C un-energised, may be continuously energised at 200°C and has outputs up to 90W/m – and this remains, to this day, a higher capability than any other competitor worldwide.

2011 - The world's first subsea electrically heat traced, reeled Pipe-in-Pipe system. 24Km of Longline heating cables heat a gas condensate pipeline for the Islay Gas and Condensate field located in the UK waters of the North Sea.
