Industrial double tube
(DTI series)



Our double-tube heat exchanger DTI series comprises an inner and outer tubes. The product flows through the inner tube, and the service fluid flows through the space between both tubes. The corrugated surface of the inner tube increases heat exchange levels. The geometry of our DTI series heat exchanger produces a real counter-current flow. It is further equipped with bellows or an expansion joint to balance out the differential expansion of the inner and outer tubes during functioning, thus considerably extending its lifespan.


Recommended for the following products
