What Energie Transfert Thermique does
Energie Transfert Thermique (ETT) is a French industrial manufacturer founded in 1979 and headquartered in Ploudalmézeau, Brittany, that designs and builds bespoke air treatment systems — rooftop heat pumps, air handling units (CTA ULTI+), liquid chillers (EC+), dehumidifiers (DESHU XP+), and 100% fresh air heat pumps (X-RCAM+) — for commercial, industrial, healthcare, aeronautical, and tertiary applications. The company differentiates on proprietary technology: full-aluminium chassis and casing with a 20-year anti-corrosion warranty, ultra-low-GWP R290 propane refrigerant (GWP 0.02) deployed across the ULTI+ R290 and NEROMAX ranges, adiabatic cooling systems delivering up to 68% energy savings versus purely thermodynamic solutions, and Eurovent-certified efficiency classifications. A 14-person R&D team across four competency areas drives continuous product development, including 2024 launches of the NEROMAX reversible heat pump and ULTI+ R290 ADIA/EX/EX2 variants, and a 2026 hygienic fresh air solution for healthcare.
ETT operates a direct sales-led go-to-market model through eight regional sales managers covering France, plus wholly-owned subsidiaries in Poland, Kazakhstan, and Romania and channel partners in Italy, Hungary, and Portugal, reaching customers in 26+ countries. Revenue is generated across four streams: bespoke hardware sales (HVAC equipment manufactured to order), installation and commissioning services (ETT Services), managed energy performance monitoring (myETTvision and C2PE contracts), and spare parts. Reference customers include L'Oréal, ELIS, ASTEN, Pathé, Halle aux Fleurs (Rungis), DOORTAL, and Menuiserie de l'Atlantique, spanning cosmetics, industrial laundry, data centers, cinema, food wholesale, and joinery. The company is privately held (SAS structure, SIRET 31660722500018), family-owned, employs 350+ people, holds ISO 14001 certification since 2010, has received EcoVadis Gold Medal in 2025 and 2026, and has committed to a 48% reduction in greenhouse gas emissions by 2030.
