1:1: same port-to-port dimensions (479 × 72 mm) and connection G1" external thread

No modifications, no adapters: thanks to identical port-to-port dimensions (479 × 72 mm) and the same G1" male thread connections, the UNEX PBU20 replaces the GEA WTT GBS525H fully 1:1. The new exchanger fits directly onto the existing pipework; installation is therefore a matter of swapping. The PBU20 is a brazed plate heat exchanger with plates of AISI 316L stainless steel, copper brazed. The series runs from 10 to 100 plates; order the version with the same plate count as your current GBS525H. A GEA WTT GBS 525H-50, for example, matches the PBU20-50 — use the table above to look up your type number. If you are unsure which version you need, we are happy to work that out with you. Most versions are in stock in our warehouse in Oosterhout (the Netherlands) and are delivered quickly. Want certainty about the right version, or a price straight away? Call +31 (0)162 429 068 or request a no-obligation quote; you will receive a quotation within one working day.
