Is there an APV OLC 85 running in your installation that is due for replacement? The UNEX PBG45 is the 1:1 alternative. Thanks to identical port-to-port dimensions (460 × 198 mm) and the same G2" male thread, the PBG45 slides directly into the place of the old unit; nothing about the pipework needs to change. This brazed plate heat exchanger with AISI 316L stainless steel plates, copper brazed, is available from 30 to 150 plates. Choose the version with the same number of plates as your current OLC 85; the table above points out the correct replacement for each type number, for example the PBG45L-80 for the APV OLC 85/80 AE. Some versions are in stock in our warehouse in Oosterhout (the Netherlands); the others are available quickly on request. Questions about the right choice, or would you like a price? Call +31 (0)162 429 068 or request a no-obligation quote — you will have our price proposal within one working day.
