Decometa has been engineering and manufacturing several types of machines, vessels , heat exchangers, air cooled heat exchangers  and air cooled condensers for special needs in the chemical-, petrochemical- and metallurgical sector since 1953.

Within our 7000 m2 fabrication facility on our 30.000 m² site, we design and manufacture high quality metal constructions.

In reference to the sector of industrial process cooling , Decometa is a well known specialized manufacturer for tailor made solutions including the process design, the construction and the installation of the entire units.

Decometa has the capability of manufacturing all components of an air-cooled heat exchanger including the tube bundles, as well as its associated structures and mechanical equipment. DECOMETA has a complete top notch welding and weld cladding ( weld overlay and inlay ) capability, utilising the latest automated pulse T.I.G weld stations.

Decometa has a long experience in custom-made designs and manufacturing for various specific  industries such as:


petrochemical industry, steel and non-ferro industry, power-generation, nuclear-, conventional agriculture, waste processing industry


Decometa owns the licenses for the design and fabrication in accordance to

PED  Module H1 ,HPO.

Decometa is ISO 9001 :2015 certified

Performance optimizing

Image column 3

Air cooled heat exchangers can give reduced performance due to age, poor design, process and poor airside distribution, fouling, mechanical problems and many other factors.

Decometa provides a service for retrofitting , debottlenecking, upgrading or maximizing the performance. The cooling capacity of your AirFin cooler, or condensers can be boosted and optimized by our experienced heat transfer and mechanical engineers.

The skilled DECOMETA task force of engineering, production, and construction specialists stands ready to upgrade your air cooled heat exchangers, whether from DECOMETA or not .

Engineering /re-engineering will be done in accordance with customer requirements and industry standards such as ASME, API 661, AD2000, CODAP, Dutch Rules for pressure vessels and ISO standards.

A better understanding of the system’s functioning allows the end-user to make energy savings and the plant efficiency will be improved!
