PHARMAFLO Heat Exchanger is realized to meet the pharmaceutical industry need/request of high hygienic measures. PHARMAFLO Heat Exchanger is manufactured by small diameter corrugated tubes inside an external jacket with tube plate on both ends. This solution remove the possibility of any contamination between sterile product and service fluid. An expansion joint is fitted on external jacket. The product to be thermally processed flows inside the small diameter tubes while service fluid flows inside the external jacket Application range Particularly suited for thermal exchange process of pharmaceutical fluids having a low or medium viscosity as for example WFI point of use cooling - WFI heating - condensation.
