D'Hondt Thermal Solutions

What D'Hondt Thermal Solutions does

D'Hondt Thermal Solutions (DH-TS) is a French-headquartered, privately held designer and manufacturer of Air Cooled Heat Exchangers (ACHE) serving oil & gas, petrochemical, refining, power generation, and select industrial customers globally. Its core offering centers on API 661 air coolers built around three proprietary finned tube technologies (KLM knurled, embedded G-type, and extruded), operating across temperature envelopes up to 400°C, with complementary non-API products (coils, dry coolers, pressurized steam condensers), a thermal energy storage and waste heat recovery product line, and a digital monitoring product called DHTS Box. The company generates revenue primarily through custom, project-based one-time sales of engineered modularized heat exchangers to large EPC contractors and end-user operators, supplemented by multi-year aftermarket services (spare parts, cleaning, supervision, upgrades, drone inspection).

DH-TS operates an enterprise field sales motion with engineering and project management centralized in Valenciennes, France, and manufacturing executed at wholly-owned facilities in Jubail, Saudi Arabia (qualified by Saudi Aramco, capacity for approximately 300 bundles per year) and Gunsan, South Korea, enabling local content and freight-cost advantages on Middle East and Asian projects. Channel relationships with major EPCs (Technip Energies, KZJV, ICA Fluor, Techint, TP Oil & Gas) and direct awards from operators (Larsen & Toubro for Jafurah Phase II, Methanex, Saudi Aramco, KPI Kazakhstan) drive a project-lumpy revenue profile. The company is a wholly-owned subsidiary of the German Grossmann Group since December 2018, has installed over 10,000 air coolers since 1960, and maintains sales representation in 50+ countries while employing between 251 and 500 people.
