The UNEX PBG45 replaces the GEA H57 1:1. That means: identical port-to-port dimensions (460 × 198 mm), the same G2" male thread connections and installation without modifications to the existing pipework. Old exchanger out, PBG45 in — and your installation is running again. As a brazed plate heat exchanger, the PBG45 is built from plates of AISI 316L stainless steel, copper brazed. For the H57 series we supply versions from 30 to 120 plates; take over the plate count of your current exchanger. The GEA H57-120, for example, corresponds to the PBG45H-120, and the table above shows the matching replacement for each type number. Speed is often decisive when replacing. That is why some versions are in stock in our warehouse in Oosterhout (the Netherlands) and the other sizes are quickly available on request — no waiting weeks for the original supplier. Call +31 (0)162 429 068 for advice on the right version or request a no-obligation quote online. You will receive a quotation from us within one working day.
