Is the GEA WTT GBS700H in your installation at the end of its service life? With the UNEX PBG45 you replace it 1:1: the port-to-port dimensions are identical (460 × 198 mm) and the exchanger has the same G2" male thread connections. Remove, fit the new exchanger, reconnect — that is all, because the existing pipework remains unchanged. The PBG45 is a brazed plate heat exchanger with plates of AISI 316L stainless steel, copper brazed. The series runs from 30 to 150 plates, so there is a suitable replacement with the same plate count for every GBS700H version. The GEA WTT GBS 700H-44, for example, becomes the PBG45H-44. There is no need to wait for the original supplier: some versions are in stock in our warehouse in Oosterhout (the Netherlands), the rest are quickly available on request. Check the table above to see which type matches your GBS700H, or call +31 (0)162 429 068 for advice. You can of course also request a quote; you will receive the quotation within one working day.
