You replace the Reflex RHC40 1:1 with the UNEX PBU11. Both units have identical port-to-port dimensions (281 × 72 mm) and the same G1" male thread, so the PBU11 takes the place of your current heat exchanger without modifications. The PBU11 is a compact brazed plate heat exchanger with AISI 316L stainless steel plates, copper-brazed. The series is available from 10 to 70 plates; choose the version with the same number of plates as your RHC40. The PBU11-70, for example, replaces the Reflex RHC 40/70. If you are unsure about the right size, we are happy to advise. Some versions are in stock at our warehouse in Oosterhout (the Netherlands); the other sizes are quickly available on request. Cold insulation against condensation or a thermal insulation cover can also be ordered along with it. Look up your type number in the table above to find the right replacement. Questions?
