As a replacement for the APV OHC 85 we supply the UNEX PBG45: a 1:1 alternative with identical port-to-port dimensions (460 × 198 mm) and the same G2" male thread. The new heat exchanger therefore takes the exact place of your current OHC 85, without modifications to the pipework or extra adapters. The PBG45 is a brazed plate heat exchanger with AISI 316L stainless steel plates, copper brazed, and is available from 30 to 150 plates. In the table above you will find the matching version for each OHC 85 type number — the APV OHC 85/140 AE, for example, corresponds to the PBG45H-140. Some versions are in stock in our warehouse in Oosterhout (the Netherlands); anything not in stock we deliver quickly on request. Not sure which version you need? Call +31 (0)162 429 068 and we will gladly help you make the right choice. Or request a no-obligation quote straight away; you will have a price proposal within one working day.
