Heat Exchangers - Scraped Surface Heat Exchanger
HRS - Model Unicus Series - Reciprocating Scraped Surface Heat Exchanger
The patented HRS Unicus Series is a scraped surface heat exchanger specially designed and developed to offer a solution for those difficult heat transfer applications where very viscous fluids are used or fouling appears. The design is based on a traditional shell and tube heat exchanger with scraping elements inside each tube. The reciprocating movement of the scrapers mix the fluid whilst cleaning the heat exchange surface. This keeps heat transfer high and reduces downtime. In addition, the scraping movements introduce turbulence in the fluid increasing levels of heat transfer.
HRS - Model R Series - Rotating Scraped Surface Heat Exchanger
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.
