Is your Kelvion GBS757M due for replacement? The UNEX PBG45 is the 1:1 alternative. Thanks to identical port-to-port dimensions (460 × 198 mm) and the same G2" male thread, the new heat exchanger connects directly to the existing pipework; modifications or adapters are not needed. The PBG45 is a brazed plate heat exchanger with AISI 316L stainless steel plates, copper-brazed. Available from 30 to 150 plates, so there is a suitable size for every GBS757M version: the Kelvion GBS 757M-90, for example, is replaced by the PBG45M-90, with the same number of plates. Some versions are held in stock in Oosterhout (the Netherlands); the rest are quickly available on request. If you are unsure which version you need, we are happy to look into it with you. Please state the type number of your current GBS757M with your enquiry; we will then verify the right version straight away. Call +31 (0)162 429 068 or request a no-obligation quotation online — you will have our quote within one working day.
