When a brazed plate heat exchanger reaches the end of its service life, you want a suitable replacement quickly. For the GEA WTT GBS500H that is the UNEX PBU20: identical port-to-port dimensions (479 × 72 mm) and the same G1" male thread connections, so replacement proceeds without changes to the pipework. Downtime of your installation is thus kept to a minimum. The PBU20 has plates of AISI 316L stainless steel and is copper brazed. With versions from 10 to 100 plates, there is an alternative with the same plate count for every GBS500H. A GEA WTT GBS 500H-34, for example, is replaced by the PBU20-34; you can easily look up your type number in the table above. We deliberately keep a large stock of the PBU20: most versions are in our warehouse in Oosterhout (the Netherlands) and can therefore be delivered quickly. Request a no-obligation quotation — you will hear from us within one working day — or call +31 (0)162 429 068.
