In addition to the production of complete new tubular heat exchangers, we offer the production of replacement parts for existing heat exchangers, such as replacement bundles, boxes, calendars, floating bottoms, etc., as well as the repair of existing equipment or parts of existing equipment in our workshops.

Among this possible revamping work, Delaunay et Fils has a very wide experience as well as the expertise and responsiveness required for exchanger de-tubing / re-tubing work (replacement of all the used tubes of an exchanger, an air cooler or a TLE exchanger).

This work can be carried out in the shortest possible time (shift work including weekends) according to the needs of the exchanger user in the context of scheduled or unscheduled unit shutdowns.
