Tubular heat exchangers

We have specialised in the design and manufacturing of tubular heat exchangers (“TEMA” type) for more than 60 years. The “Delaunay” heat exchangers produced are of all types and successfully perform a wide variety of functions in many process units around the world.

Delaunay et Fils designs and manufactures all types of tubular exchangers for its customers, such as single-phase or two-phase simple exchangers (liquid/liquid, gas/gas, liquid/gas), condensers, refrigerants, evaporators or reboilers, economisers, vapourisers (oxygen, nitrogen, LNG, etc.), but also specific equipment such as steam generators and recovery boilers, falling film exchangers, “bun” exchangers, “Texas Towers”, “Rod Baffles” exchangers, “High Pressure” or “Very High Pressure” exchangers (with a possible boltless HP sealing system developed by Delaunay et Fils for pressures up to 450 bar and a sealing system resistant to the phenomenon of explosive decompression”), sulphur condensers, etc.
