The HRS R Series of tube-in-tube heat exchangers uses a scraper bar within each inner tube to enhance product flow, prevent fouling, and minimize pressure drop. A key feature of the R Series is that the scraper bar features a helical screw that rotates at high speed. When configured correctly, this screw can be run in reverse, effectively emptying the heat exchanger tubes of product without damaging it or changing its characteristics.

The system is particularly suitable for high-value viscous products such as honey, treacle, custards, and creams, where any loses of product can be economically important. The R Series can be emptied of the majority of product without the need for any additional pumps or pressure systems. This provides advantages in terms of both capital- and running-costs.

The R-Series can be configured for both horizontal and vertical operation, so that gravity can also be used to help recover product from the tubes. Each unit can be supplied with one, three, or six tubes and multiple units can be combined for larger installations. Due to the amount of product saved, and the fact that it is often unnecessary to install additional product recovery systems, the R Series heat exchanger can quickly pay for itself, and in the long term can be a more economic option than alternative systems.
