HRS Heat Exchangers Ltd. products

The HRS DTI Series is a complete stainless steel double tube heat exchanger designed for industrial applications. Because of its geometry the DTI Series is a true counter current heat exchanger; the product flows through the inner tube and the service fluid flows through the surrounding shell. Using our corrugation technology, both heat transfer and efficiency are increased over standard smooth tube heat exchangers. In addition, potential fouling is minimised. Expansion joint (bellows) is fitted in the shell to allow for differential expansion of the inner and outer tube during operation. Multiple units can be interconnected and have the options of frame mounting, insulated and cladded in stainless steel. The HRS DTI series is suitable for applications with fluids containing fibres or particles and low-high viscosity fluids.

Based on the DTI Series, but with an adapted design for direct energy recovery (product vs product) for sludge with low viscosity. The inner tube is removable making it possible to inspect/clean both tube and shell side. It also allows for easier and faster cleaning consequently reducing operational downtime required for these high fouling products. The tube in tube concentric geometry makes it easy to work with fluids that contain particles, without having to worry about blockages impeding the flow of product. Special corrugated tubes are used to increase heat transfer and reduce fouling, making the DTR Series more efficient than similar smooth tube heat exchanger designs.
