Sanitary Double Tube Heat Exchangers – HRS DTA Series

The HRS DTA Series is a complete stainless steel double tube heat exchanger designed for sanitary applications.

The product flows through the inner tubes and the service fluid flows through the surrounding shell. Because of its geometry, the DTA Series is a true counter current heat exchanger. Using our corrugation technology, both heat transfer and efficiency are increased over standard smooth tube heat exchangers. In addition, potential fouling is minimized.

Bellows are fitted to absorb differential expansion between shell and tube and multiple units can be interconnected for larger applications. Options include frame mounting, insulation and stainless steel cladding.

HRS DTA Series is suitable for fluids containing fibers or other particles and low-high viscosity fluids. For high viscosity food products like honey, fruit jams and marmalades, please refer to our Annular Space and Scraped Surface Heat Exchangers product range.
