APV/Crepaco single tube scraped surface heat exchanger model 1HD-884. Last used in a food application.
HRS offers three types of corrugated tube heat exchangers:Annular Space Heat Exchangers; Double Tube Heat Exchangers; Multitube Heat Exchangers Scraped Surface Heat Exchangers. For difficult heat transfer applications, with high viscosities and where fouling can become a problem, the preferred option is a scraped surface heat exchanger. The reciprocating or rotating movement of the scrapers Rotating Scraped Surface Heat Exchangers HRS R SeriesRotating Scraped Surface Heat Exchangers HRS R Series. 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.
The Kelstream continuously scrapes the whole heated or cooled surface, resulting in an extremely efficient heattransfer. This scraping principle has a major efficiency advantage compared to conventional plate or tube-shaped heat exchangers. Furthermore, this prevents the product from sticking to the surface. Two heat transfer surfaces Scraped Surface Heat Exchangers HRS Heat ExchangersScraped 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
Feb 12, 2021 · In those applications, scraped surface heat exchangers are the best method to provide effective heat transfer due to the scraping blades that keep product from settling on the interior surfaces. Product enters a cylinder at the bottom of the scraped surface tube. Why use corrugated tubes in heat exchangers?
The rechroming of scraped surface heat exchanger product tubes is a n important aftermarket service to ensure the effectiveness and s afe use of scraped-surface heat exchangers.In order to maintain pressure vessel integrity and comply with local and
