Created in 1919, DELAUNAY & Fils, armed with a double expertise in mechanical and metal works, has specialized in the 1950s in the study and manufacturing of Pressure Vessels, especially in customized Shell & Tube Heat Exchangers for the Refining, Petrochemical and Chemical industries.
Thanks to sound references and its reliability, DELAUNAY ‘s customer base has expanded from its customers initially based in Normandy (refineries and petrochemical units in Le Havre and its area) to a national scale and then to industrial sites abroad through international engineering companies.
Today the expertise of DELAUNAY & Fils is renowned internationally. We are recognized for the quality and technicality of our work, for the performance, reactivity and flexibility of our teams who are keen to respect deadlines and meet contractual engagements. Around one hundred qualified and experienced collaborators design and manufacture specific equipment in different sizes (up to 170t each) and in a wide range of materials, on our 15 000 m2 plant in Le Havre.
The custom-made pieces of equipment we manufacture are mostly Shell and Tube Heat Exchangers – complete or partial: bundles, channels, shells etc.) Our skills also extend to other types of pressure vessels / equipment (tanks, columns, air cooler bundles, reactors, etc.) and the repair and reconditioning of exchangers in our workshop (detubing / retubing, modification…).
More than 50% of the exchangers we design and manufacture are exported and installed at our clients’, worldwide.
To date, along our 100 years of existence – including 60 years of experience in Shell and Tube Heat Exchangers – around 10 000 tailor-made exchangers, all complying by our clients’ strict specifications, have left our workshop.
