Effective and Safe Heat Transfer for Viscous and Particulate Fluids by using Scraped Surface Heat Exchangers in Food, Dairy, beverage and allied Industries.


In general, the more viscous the fluid, the lower the heat transfer is. This means that very viscous fluids require a very large heat transfer area. Scraped surface heat exchangers vigorously mix the fluid, which helps to move the fluid to and from the heat exchange surface. This increases heat transfer rates, so the total area required for heat exchange is reduced.


For difficult heat transfer applications, with high viscosities and where fouling can become a problem, the preferred option is a scraped surface heat exchanger. Scraped surface heat exchangers keep heat transfer high and the heat transfer surface is constantly cleaned.

HRS offers two technologies for scraped surface heat transfer: the patented HRS Unicus Series which reciprocates and R Series which rotates, each designed for specific needs.
