The biopharm industry requires exceptional certainty, not only when it comes to product hygiene, but also when it comes to isolating products and media. For this reason, Alfa Laval offers a number of specially developed, highquality tubular heat exchangers. Designed for point-of-use cooling in the biopharm industry, the Pharma-X tube-in-tube heat exchanger eliminates the risk of contamination between the product and cooling media. It consists of three discrete tubes arranged one within the other, curved through 180º to create a bend that takes up thermal expansion. The Pharma-X heat exchanger can be used in many application areas, including point-of-use cooling on WFI (Water For Injection) ring mains, cooling/heating of pure water in the biopharm industry and cooling/heating of distilled water/ WFI for processing equipment. PharmaLine is a double tube sheet (DTS) shell-andtube heat exchanger that provides full drainability and prevents the risk of cross-contamination. Its bundle of seamless, electropolished tubes handles the flow of product media, with service media running outside the tubes in a crossflow. Since the unit is flexible in design, size and material, it can be used in any hygienic application with high demands. Typical uses for PharmaLine are in water systems, water for injection, purified water and CIP (cleaning-in-place) systems. PharmaLine is also used for general product heating and cooling duties.
