Leakage, fouling or declining performance: sooner or later every brazed plate heat exchanger is due for replacement, including the GEA WTT GBS757L. The UNEX PBG45 takes its place 1:1: the port-to-port dimensions are identical (460 × 198 mm) and the connections are the same — G2" male thread. Installation therefore proceeds without modifications or adapters. The PBG45 has plates of AISI 316L stainless steel, copper brazed, and is available from 30 to 150 plates. Replace your exchanger with the version with the same plate count; the GEA WTT GBS 757L-60, for example, becomes the PBG45L-60. In the table above you can see the correct replacement for each type number. Delivery times are covered too: some versions are in stock in our warehouse in Oosterhout (the Netherlands), the rest are quickly available on request. Your installation is thus back up and running quickly, without waiting weeks for the original supplier. Call +31 (0)162 429 068 for advice or request a no-obligation quote — you will have a quotation within one working day.
