Sterling Thermal Technology

About us

We are a leading heat exchanger manufacturer

As one of the leading UK heat exchanger manufacturers, Sterling Thermal Technology is experienced and trusted. Acting as a technical partner to many of the world’s leading businesses, we design and manufacture heat exchangers to custom specifications – from first principles to lasting partnerships. 

We are a business with a proud pedigree. Previously known as HEI, Thermo Engineers, Britannia Heat Transfer, Thame Energy Services and Britannia Heatex, we have over 100 years’ continuous experience in the heat exchange industry. Throughout our history, we have been at the forefront of technology, developing new and pioneering solutions to meet the changing demands and challenges of the global industry.

With a track record of collaboration with global brands and SMEs in over 50 countries, we’ve demonstrated our ability to solve the most complex challenges across all industry sectors; from power generation, oil and gas to chemical, pharmaceuticals and food & beverage, through to marine, defence and rail & transportation.

Facilities

Heat exchanger manufacturers, based in the UK but operating globally, we have two modern and well-equipped heat exchanger factories. The reason is that we continually invest in our facilities, people and process to ensure we evolve to meet our demanding customer requirements – from concept through to realisation.

Our manufacturing facilities in Aylesbury and Birmingham have dedicated heat exchanger production lines for Original Equipment Manufacturers (OEM) and end-users' requirements. We manufacture to both bespoke and standard designs for new, like-for-like replacement, enhanced or refurbished units. In addition, our facilities also enable us to manufacture one-off or mass volume heat exchangers.

Research & Development

When it comes to Research and Development, we have an inclination to think differently and a mission to challenge the status quo to ensure our products are:

  • safe
  • extremely efficient and reliable
  • simple and user-friendly
  • cost-effective.

We connect at different levels with R&D Institutions, Universities, EPCs, Technology (Process) providers and end-users sharing similar values and beliefs and building long-lasting relationships. We are also committed to working closely with our clients to improve, innovate or adapt our heat exchangers to meet evolving needs and demanding operating conditions.

As a result, we have designed and manufactured heat exchangers, which met hush design conditions, being high temperatures (over 600°C) and pressures (over 200 barG), enable to withstand corrosion attack of aggressive fluids or fulfil complex process requirements by chemical processing.

Using both advanced design tools which include Ansys, Aspen, HTRI and Solidworks; and experimental work, developments we have worked on. These include but are not limited to:

  • extended surfaces capable of reducing thermal stresses to an acceptable level, which would otherwise cause premature failure of either steam or thermal oil heaters used in dairies for milk powder production or economisers used in waste heat recovery systems;
  • coatings which provide smooth and prolonged operational life of our coolers in an off-shore environment;
  • more complex shell & tube heat exchangers with extended surfaces,
  • improved leak safe solutions.

Our commercial, design, production and marketing teams also actively evaluate new applications for existing proven products, adapting them to suit specific markets.

Quality & Accreditations

Both of our manufacturing sites are certified ISO 9001:2015 because we want to ensure you get consistent, good quality products and services.

Design capabilities

Our design department works to:

  • all the usual design codes including ASME VIII, BS5500, API 12, API 560, TEMA and CODAP,
  • the major manufacturing specifications and rules including NORSOK, BV, DNV, Lloyd’s Register and NKK.

Third-party inspection

For both design verification and final inspection, we regularly work hand in hand with third-party inspection authorities such as Lloyds Register, BSI, DNV (Norway), BV (UK), ABS (US) and NKK (Japan).
