The UNEX PBG45 is the 1:1 replacement for the Funke GPL7. The port-to-port dimensions are identical (460 × 198 mm) and the connections are the same G2" male thread, so the PBG45 takes the place of your current GPL7 without any modifications. The existing pipework remains completely untouched; you only swap the exchanger itself. As a brazed plate heat exchanger, the PBG45 is built from plates of AISI 316L stainless steel, copper brazed. The series is available from 30 to 150 plates; when ordering, keep the same plate count as your current exchanger. A Funke GPL 7-44-H-30, for example, is replaced by the PBG45H-44 — the table above shows the correct alternative for each type number. A large share of the versions is in stock in Oosterhout (the Netherlands), so replacement usually does not have to take weeks. Matching insulation can easily be ordered along with it. If you request a quote, you will receive a quotation within one working day. Prefer direct contact? Call +31 (0)162 429 068.
