Hamon started its industrial activities in Europe (Belgium and France) a century ago and developed the cooling tower business. Hamon spread its wings geographically in the seventies and further consolidated the thermal business in the nineties. Hamon became a world leader in the product lines it chose to be in, respectively:
• Wet cooling towers
• Air-cooled heat exchangers
• Air pollution control
With over 50 years of experience in the field of heat exchange, Hamon D’Hondt can address and resolve all clients’ needs in air-cooled heat exchange. Hamon D’Hondt designs and manufactures air-cooled heat exchangers (ACHE) and finned tubes and can offertheir products to chemical, petrochemical, power and heat recovery industries. Hamon D’Hondt has developed significant innovative technologies in the design and fabrication of high pressure equipment and in the manufacturing of components made with special materials such as Titanium, Hastelloy, Incoloy, Duplex, Super Duplex, Monel and Nickel Alloys. Thanks to its consolidated design and manufacturing experience combined with the adoption of improved design and fabrication concept, Hamon D’Hondt is able to give a high technological contribution to the completion of industrial plants and implementation of energy programs
worldwide. Hamon D’Hondt specialises in the design and manufacture of the following products for chemical, petrochemical and power generation plants:
• Air-cooled heat exchangers (API 661)
• Tube bundles
• Aluminium finned tubes
• High frequency and studded welded finned tubes
The complete service starting from thermal and mechanical engineering to the complete manufacture, including the internal design and supply of the main components like finned tubes, fan hubs, fan blades, etc, guarantees Hamon D’Hondt supplies for the best performance and efficiency.
Hamon D’Hondt has a large factory in Fresnes-sur-Escaut (France) with a covered area of 17.550 m2 on a total surface of 115.000 m2. The workshops are equipped with the most modern machinery for proper manufacturing and control of the complete air-cooled heat exchangers.
Hamon D’Hondt has a factory in Jubail Industrial Area (Saudi Arabia) with a covered area of 3.500 m2 on a total surface of 12.000 m2. The workshops in Saudi are performing tube finning, bundle assembly, air-cooled heat exchanger modularizing, and all relevant tests (hydrotest, helium leak testing, vibrations, noise...), whereas the pressure parts (headers) are being manufactured in France and shipped to the Jubail factory.
Hamon Korea has been established more than 25 years ago and is now the leading company in South Korea for the supply of wet cooling towers, natural and induced draft. As Asia appeared to be a key market in the Oil & Gas business, Hamon D’Hondt decided to settle a company in South Korea to better serve its Korean and Asiancustomers and enhance its competitiveness with a local manufacturing unit.
A joint venture was first created in 2010 with its headquarter located in Seoul and factory nearby Busan. The company was very successful from its start and secured major orders around the world; to support this strong development it was decided in April 2013 to transfer the whole asset of the joint venture company to a new division of Hamon Korea, named Process Heat Exchangers Division.
Hamon Korea Process Heat Exchangers (HKPHE) is now among the market leader in Korea in its field of air coolers. Hamon Korea Process Heat Exchanger Division has a dedicated team located in Hamon Korea headquarters to ensure a smooth and easy communication with Korean EPCs. It comprises skilled project managers & engineers, thermal engineers, procurement team and administrative staff.
Hamon Korea Process Heat Exchanger Division also has its own facilities located in Gunsan, having a covered shop of 3,440 m² out of 22,308 m² total land. The shop holds ISO9001 certification, as well as ASME U Stamp and OHSMS18001.
The air-cooled heat exchangers are mostly used when the plant location and the ambient conditions do not allow an easy and economic use of other cooling systems. The most evident advantages of air-cooled heat exchangers are:
Hamon D’Hondt provides complete air cooler units including tube bundle assembly, motor-fan groups, structure, access ladders and walkways. Typical arrangement can be forced draft, induced draft, or air-recirculation unit. Hamon D’Hondt also supplies pre-assembled modules.
Typical components include headers, finned tubes, and motor-fan assembly.
Allows easier maintenance of the fans. Fans deliver air at ambient temperature with consequent higher efficiency.
The plenum chambers are mounted on top of the bundle and protect the finned surface against wind, rain, snow and partially hail. The location of the fans also ensures an optimum air distribution, limits air recirculation and allows lower level at maintenance walkway level. Fansdeliver hot air.
Recirculated / Winterization
This feature is recommended for special processes (hydrate prevention...) and cold climates, where it is advisable to provide warm air by recirculation to prevent freezing. The recirculation may be achieved by means of louvers, steam coils and variable fans.
Hamon D’Hondt produces a wide range of finned tubes (with aluminium fins) for all industrial sectors and is fully equipped to test the contact between tube and fins ensuring the expected thermal performances (pull and push test, ...).

Hamon D’Hondt designs and manufactures interchangeable tube bundles using top performance equipment. All types of air-cooled bundles can be replaced with no alteration of the heat exchange capacities and are fully adaptable to existing piping and existing structure.
The replacement bundles are redesigned according to the latest code editions and innovation standards.
Hamon D’Hondt performs the retubing of tube bundles; this is directlymade in our workshops. Hamon D’Hondt also manufactures fully interchangeable finned tubes.
For all products Hamon D’Hondt offers a full scope of services including engineering, procurement, supply of complete units, assistance at commissioning and start-up.
Hamon D’Hondt also ensures full after sales services:
Hamon D’Hondt provides all spare parts for their products, either from the ready stock (bearings, fans, motors, plugs, gaskets, ...) or manufactured on demand (header, finned tubes, bundles) in compliance with the original parts (all parts guaranteed except wear parts).
Our service is not limited to the main and most frequent replacements. We are available for any kind of supply according or not to our design; our experienced team can help you implementing and improving the performance of your equipment.
A non-exhaustive list of the products, which can be supplied as complement of our units are:
and any other parts as per your needs. The Hamon D’Hondt production range covers all types of finned tubes with aluminium fins, steel fins, etc. The finning operations are completely carried out in our workshops and guaranteed by our periodic production tests.
