Hamon Group

What Hamon Group does

John Cockerill Energy, the industrial energy arm of privately held Belgian group John Cockerill S.A., operates the Hamon® cooling business (acquired in 2022) alongside its legacy HRSG, boiler, multiple hearth furnace, and integrated renewable energy activities. The business designs, engineers, manufactures, and delivers large-scale thermal and energy technology systems for power producers, utilities, industrial operators, and hyperscale data centers worldwide, with a workforce of approximately 700 employees and operations across 11 countries including Belgium, France, Spain, the UK, the USA, the UAE, Saudi Arabia, Indonesia, South Korea, Portugal, and Mexico.

Core product lines comprise (i) Hamon® cooling towers (wet natural-draft, induced-draft, forced-draft, and air-cooled condensers) and data center cooling solutions, (ii) heat recovery steam generators (HRSGs), Once Through Boilers, Denapak and Denarad industrial boilers, biomass boilers, and offshore-certified HRSGs, (iii) integrated Power & Storage systems combining solar, wind, battery (BESS), and thermal (TESS) storage controlled by a proprietary Energy Management System, and (iv) Nesa Solution® multiple hearth furnaces (MHF) for thermal processing of minerals, biomass, waste, and sludge, augmented by the digital SMART MHF™ platform with John Cockpit™ and John Connector™ cloud connectivity. Installed base exceeds 750 HRSGs, 6,000 cooling towers, and 150 MHFs across five continents.

Revenue is generated predominantly through large one-time capital equipment sales and EPC turnkey contracts for utility, industrial, and data center customers, supplemented by recurring after-sales services spanning inspections, CO2 cleaning, revamping, preventive maintenance, remote monitoring, and spare parts. Go-to-market is direct enterprise field sales with technical FEED study support, distributed through regional offices and supported by partnerships with tier-1 gas turbine OEMs (GE, Siemens, MHPS, Ansaldo). The company holds proprietary certifications including TÜV-SÜD H2-Readiness (December 2024), DNV offshore certification, ISO 9001 and ISO 45001, EUROVENT drift eliminator certification, and continuous Cooling Technology Institute membership since 1960.

• Babcock & Wilcox: B&W is a direct peer in industrial boilers, HRSGs, and thermal power plant equipment serving utilities and industrial customers globally. Both companies compete in waste-to-energy, biomass boilers, and HRSG retrofits, with overlapping customer bases in North America and EMEA.
• SPX Technologies (Dry Cooling): SPX Technologies' Dry Cooling division (formerly Hamon-Fival) is a direct competitor in air-cooled condensers and dry cooling solutions for power plants and industrial applications. Directly competes with John Cockerill Hamon in the ACC and dry cooling market globally.

Emerging players

• Thermax Limited: Thermax is an Indian industrial boiler and cooling solutions manufacturer competing with John Cockerill in biomass boilers, industrial boilers, and absorption cooling. Strong in emerging markets and increasingly expanding into integrated energy solutions.

Broad incumbents

• GE Vernova: GE Vernova is the gas turbine OEM customer for John Cockerill's HRSGs but also a broad incumbent in power generation equipment. Represents the largest single HRSG customer opportunity while also competing in integrated CCGT plant delivery across global markets.
• Siemens Energy: Siemens Energy is both a customer (gas turbine partner for HRSG installations) and a broad incumbent offering integrated CCGT power plants with in-house HRSG capability. Represents both partnership opportunity and competitive threat in the HRSG market as Siemens increasingly bundles equipment.
