A GEA WTT GBE400H that is due for replacement does not have to become a search. The UNEX PBU11 is the 1:1 alternative: identical port-to-port dimensions (281 × 72 mm) and the same G1" male thread connections, so you simply keep using the existing pipework. Replacement thus remains limited to swapping the exchanger itself — quick and without extra adapters. The PBU11 is a brazed plate heat exchanger with plates of AISI 316L stainless steel, copper brazed. The series comprises versions from 10 to 100 plates; choose the plate count that matches your current GBE400H. A GEA WTT GBE400H-40, for example, is replaced by the PBU11-40. The table above links each type number to the correct replacement. Most versions are in stock in our warehouse in Oosterhout (the Netherlands) and are delivered quickly. Request a no-obligation quote — you will have a quotation within one working day — or call +31 (0)162 429 068 if you would like to discuss the right version first.
