Looking for a 1:1 replacement for the Kelvion GBS500H? The UNEX PBU20 can be installed without modifications: identical port-to-port dimensions (479 × 72 mm) and the same G1" male thread connections. The existing pipework remains fully intact. The PBU20 is a brazed plate heat exchanger, built from AISI 316L stainless steel plates, copper-brazed. The series ranges from 10 to 100 plates. When ordering, keep the plate count of your current unit: a GBS 500H-24 is replaced by the PBU20-24. We deliberately keep a large stock of this series: most versions are held at our warehouse in Oosterhout (the Netherlands) and are delivered quickly. Matching insulation — cold insulation against condensation or a thermal insulation cover — can be ordered along with it. Do you know the type number of your GBS500H? Look it up in the table above to find the right version. Prefer to call? You can reach us on +31 (0)162 429 068 — or request a no-obligation quotation and receive a quote within one working day.
