Looking for a replacement for your Kelvion GBS525L that fits straight away? Then the UNEX PBG20 is the answer. The port-to-port dimensions are identical (476 × 69 mm), so the PBG20 takes the exact place of your current unit and the pipework does not need to be modified. The connections are 22.35 mm solder or G1" male thread (combi connection: both usable). That means one port that you either solder or connect with a threaded fitting. The PBG20 is a brazed plate heat exchanger with AISI 316L stainless steel plates, copper-brazed, and is available from 10 to 100 plates — choose the same number of plates as your GBS525L. A GBS525L-20 is replaced by the PBG20L-20. Some versions are in stock at our warehouse in Oosterhout (the Netherlands); the rest are quickly available on request. In the table above you will find the matching version for each type number. Unsure which version to choose, or would you like a price first? Call +31 (0)162 429 068 or request a no-obligation quotation — you will receive a response within one working day.
