Thermal Transfer Technology

What Thermal Transfer Technology does

Thermal Transfer Technology Ltd (trading as 3T) is a UK-based, privately held custom manufacturer of finned tube heat exchangers and related thermal equipment, headquartered at Seaham Grange Industrial Estate, County Durham, England. Founded in 1990 in its current form and tracing engineering heritage to a Danish business started by Mogens Thomsen in 1961, the company operates a 5.85-acre site with over 6,000m² of custom-built production space and employs roughly 100 full-time staff split between 17 office personnel and 80 production workers across multiple shifts. It positions itself as one of Europe's major manufacturers of finned tube heat exchangers and serves industrial and commercial refrigeration, HVAC, power generation, oil & gas, petrochemical, nuclear, marine, data centres and telecoms, pharmaceutical/chemical, and food & beverage customers across the UK and Europe.

Its core technology is the design, fabrication, and assembly of custom finned tube coils and integrated heat-exchange units in copper, stainless steel, and titanium materials, including rare fully-titanium fin-and-tube coils. The product portfolio spans finned tube coils, dry air liquid coolers, air cooled condensers, room coolers, adiabatic systems, trans-critical CO2 gas coolers (with proprietary free-floating coil architecture), environmental enclosures, and custom control panels featuring EC fan controllers and inverter variable-speed drives. The company holds ISO 9001 quality management certification, PED certification for coils as pressure vessels, and TÜV: Essen independent test-house approval, with CE-marked CO2 gas coolers under the Pressure Equipment Directive (97/23/EC).

The business model is project-based custom manufacturing: revenue is generated through one-time equipment sales of bespoke, specification-driven units priced on a quote basis rather than recurring or subscription revenue. Go-to-market is enterprise field sales — direct customer engagement via phone and email to engineering and procurement teams — supplemented by inbound digital channels including a website, LinkedIn, and Twitter. Lead times run as short as 4–5 weeks for titanium coils, with standard duties ranging from 1.5 kW (room coolers) to 1,000 kW (trans-critical CO2 gas coolers). The company is family-led under Managing Director Anders Thomsen, with no disclosed external institutional investment.
