The Dimpleflo Double Tube Sheet Heat Exchanger (also known as Shell & Tube Double Tube Plate Heat Exchanger) provides the highest levels of product integrity in multitube heat exchanger designs. Dimpleflo Multitube Double Tube Plate Heat Exchangers are constructed with two separate tube sheets at each end of each tube bundle. The inner dimpled tube bundle is inserted and becomes connected with the outer tube shell with double flanges at each end i.e Double Tube Sheet. The primary liquid or product is supplied to a combination of heat transfer tubes while the service fluid flows between and around the tubes within the outer jacket. The first tube plate caps the heating or cooling media in the heat exchanger jacket, and the second tube plate seals the product (or primary) flowpath. This results in a visible gap between the two liquids which provides immediate leak detection. This leak detection, combined with seamless tube, reduces the possibility of cross contamination as far as practically possible.
Unlike corrugated tube heat exchangers, Teralba DTS Heat exchangers are designed to completely free-draining. Sanitary DTS Heat Exchangers are typically used for heating or cooling very high value products such as vaccines and medicines where any cross-contamination can be very expensive and possibly dangerous.
The DTS heat exchanger jacket can incorporate expansion bellows to overcome differential expansion between the jacket and inner tube bundle. Double Tube Sheet Heat Exchangers are often installed in “cleanrooms” and include seal welded stainless steel clad insulation and adjustable mounting feet, to minimise any crevices on the outside of the heat exchanger.
Dimplelfo Hygienic Heat exchangers can be manufactured with dimpled stainless steel heat transfer tubes, seamless tubing and for applications such as blood plasma processing, internally electropolished tubing with surface finish of 0.4um Ra.
Teralba have full quality assurance program and have supplied DTS Heat Exchangers into most pharmaceutical and biopharm facilities in Australia.
