SHELL AND TUBE HEAT EXCHANGERS mixing & heat transfer Double Tube Sheets for cGMP and High Purity Applications Problem In a typical shell and tube heat exchanger, any leak in the tube sheet will cause immediate cross contamination between the process and cooling liquid. tube side seal shell side seal Solution The double tube sheet design with an intervening safety chamber prevents contamination of product and cooling liquid under all circumstances. In case of a leaking tube gasket, the product or cooling liquid runs into the safety chamber and through the purge valve. The leakage is detected immediately. The construction enables the use of various materials on the tube and shell side to meet any specific requirements. An additional feature is the installation of a product drain through the edge of the tube sheet, especially useful for complete recovery of shellside product in a vertical installation Advantages §Absolute crosscontamination proof design, even with vacuum in the shell or tube side. Shell and tube heat exchanger with double tube sheet §Custom designs use cGMP materials to meet specific applications, such as glass, SiC, glasslined steel, stainless steel, PTFE § Minimal product holdup eases cleaning and prevents product losses §Meets CIP and SIP specifications M4.400 05/09 244 SHEFFIELD STREET MOUNTAINSIDE NJ 07092 FAX 908-889-4960 908-317-2585 WWW.DDPSINC.COM 9110 FORSYTH PARK DRIVE CHARLOTTE NC 28273 EMAIL [email protected] FAX 908-889 4960 Copyright © De Dietrich Process Systems, Inc.
