The HRS R Series is a scraped surface heat exchanger designed for the most difficult heat transfer applications, for example where very high viscosities and highly fouling fluids need heat treatment. Unlike the HRS Unicus Series, where the scraper movement is reciprocal, the HRS R Series technology uses a rotary scraper rod. This scraper rod can reach velocities up to 300 rpm resulting in very high levels of shear and mixing at the heat transfer surface; dramatically increasing the heat transfer rate.
In addition to the standard R series a heavy duty version is available. The HRS RHD Series has been developed for the more demanding applications with extreme viscosities. The RHD has all the features and benefits of the standard R Series but with increased motor size and scraping rods. Extra mounting supports for the scrapers and motor enable the unit to be used under challenging conditions.
The R and RHD Series has been developed for both hygienic and industrial applications. Each inner tube contains a scraper bar fitted with a helical screw which rotates at high speed and enhances flow through the tube whilst reducing pressure drop. In addition, the continuous scraping action eliminates fouling on the inner tube wall, ensuring that the heat transfer area is clean at all times.
Some of the unique features of the R and RHD Series include:
Large heat transfer area
Single and multiple tube options, all with removable tubes
Reduced pressure drop
High level of product recovery
Low noise level gearbox
Multipass version available
