1:1: same port-to-port dimensions (281 × 72 mm) and connection G1" external thread

Same port-to-port dimensions, same connections — so no changes to the pipework. If you need to replace a Funke GPL5, the UNEX PBU11 lets you carry straight on: the port-to-port dimensions are identical (281 × 72 mm) and the exchanger has the same G1" male thread connections, so the PBU11 takes the exact place of the GPL5. The PBU11 is a brazed plate heat exchanger with plates of AISI 316L stainless steel, copper brazed. The series runs from 10 to 100 plates; choose the version with the same plate count as your current GPL5. For a Funke GPL 5-30-H-30, for example, that is the PBU11-30 — in the table above you will find the matching replacement for each type number. Most versions are in stock in our warehouse in Oosterhout (the Netherlands) and are delivered quickly. Matching insulation, such as cold insulation against condensation or a thermal insulation jacket, can be ordered along with it. Unsure about the right version? Call +31 (0)162 429 068 or request a no-obligation quote; you will receive a quotation within one working day.
