Hygienic Double Tube Heat Exchangers - HRS DTAR Series

Hygienic Double Tube Heat Exchangers – HRS DTAR Series

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

The product flows through the inner tubes and the service fluid flows through the surrounding shell. As a result of its geometry, the DTAR Series has a continuous free-pass cross section allowing large particles to be processed and reduces the risk of product blockages.

The removable inner tube allows for effective cleaning of both shell and tube, making it ideal for product to product applications. Using our corrugation technology, heat transfer and efficiency are increased over standard smooth tube heat exchangers. In addition, potential fouling is minimised.

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 DTAR Series is suitable for fluids containing fibres or other particles, and lo-high viscosity fluids.
