Discover more with the complete Contherm ® scraped surface heat exchanger range. Contherm ® heat exchangers have long been an established solution for viscous, sticky, crystallizing and particulate products. And now with the markets most complete scraped-surface portfolio, there is truly a Contherm ® for every possible need.. Alfa Laval is the only supplier that can offer both single and
liquid and semi-solid products under cooling or heating, heat transfer at major fouling of the transfer surface by the product and heat transfer at high viscosity of the product. We supply scraped surface exchangers for each required volume flow and thermal capacity How To Specify a Heat Exchanger HRS Heat ExchangersSep 22, 2017 · Scraped Surface Heat Exchangers:These are used in applications where fouling causes heat transfer rates to drop, or when viscous fluids have very low heat transfer rates.Fouling occurs when fluids degrade near the tube wall and layers of solids are deposited the tube wall. These layers work as an insulator and prevent effective heat transfer.
mechanically assisted heat exchangers, where a heat transfer surface is periodically scraped by a moving element, constitute a suitable solution for applications with severe tendency to fouling and low heat transfer rates. Dynamic heat exchangers with rotating scraping blades (SSHE) are found in commercial practice:they prevent fouling and Scrape Surface Heat Exchangers - mgnewellScrape Surface Heat Exchangers The high efficiency and productivity of a scrape surface heat exchanger results from a simple concept; heat or cool continuously moving product by providing a large heat transfer surface for a small amount of product in a
applications. The DUAL ROTOTEX (DR) Series Scraped Surface Heat Exchanger can handle product flow rates from 500 lbs./hr. to 10,000 lbs./hr. The simple, durable design of the DUAL ROTOTEX (DR) Series allows for easy disassembly of the unit for inspection, cleaning or blade replacement. Scraped-surface heat exchangewall, which could be accounted for by using the overall heat transfer coeffi.cient between the cooling medium and the apparatus. Measure-ments on water showed the cooling rate to be much faster than the theory would predict. For a Cabosil-toluene mixture the cooling rate was slower. Scraped-surface heat-transfer coefficients of 45.7, 0
Scraped Surface Heat Exchangers. HRS Heat Exchangers designs and manufactures scraped surface heat exchangers for applications where either one or both of the following problems require special solutions:fouling causes heat transfer rates to drop and viscous fluids having very low heat transfer rates.
Heat transfer solutions for low to high fouling products Applications The Contherm scraped-surface heat exchanger (SSHE) has found use within many different processes and applica-tions for manufacturing food, chemicals, pharmaceuticals, cosmetics, health and beauty products, etc. It is particularly suited for processing viscous, heat sensitive, sticky or chunky
