Larger installations often run on the same plate heat exchanger for years, until replacement becomes unavoidable. If you have a GEA WTT WP7, the UNEX PBG45 is the 1:1 alternative: identical port-to-port dimensions (460 × 198 mm) and the same G2" male thread connections. The replacement therefore takes the exact place of the WP7, without any changes to the pipework. The PBG45 is a brazed plate heat exchanger, built from AISI 316L stainless steel plates, copper-brazed. The series ranges from 30 to 150 plates, so there is a suitable variant for every WP7 version. Keep the plate count of your current unit: a WP 7L-34, for example, is replaced by the PBG45L-34. Many PBG45 versions are in stock at our warehouse in Oosterhout (the Netherlands) and are delivered quickly. Do you know the type number of your WP7? Look it up in the table above and you will see the matching replacement straight away. For advice or a quote, call +31 (0)162 429 068 or request a no-obligation quotation online: you will receive a response from our team within one working day.

Frequently asked questions about replacing the GEA WTT WP7

Will the UNEX PBG45 fit my GEA WTT WP7 without modifications?

10 of the 28 versions are in stock in our warehouse in Oosterhout, the Netherlands, and are delivered quickly. The other versions are available on request.
