Same port-to-port dimensions, same connections: anyone replacing the GEA WTT GBS-DW500H with the UNEX PBT20 does not have to change anything about the installation. The port-to-port dimensions are identical (478 × 73 mm) and the PBT20 also has G1" male thread connections. The replacement takes the exact place of your current exchanger. This brazed plate heat exchanger is built from plates of AISI 316L stainless steel, copper brazed, and is available from 10 to 100 plates. When choosing, keep the same plate count as your current GBS-DW500H; a GEA WTT GBS-DW500H-10, for example, matches the PBT20-10. All mappings per type number are shown in the table above. Some versions are in stock in Oosterhout (the Netherlands), the others are quickly available on request. Matching insulation, such as a thermal insulation jacket, can be ordered along with it. Send us your type number for a no-obligation quote — you will receive a quotation within one working day — or call +31 (0)162 429 068 for direct advice.
