The UNEX PBG45 is the 1:1 replacement for the APV SPX TTG45H. Both have the same G2" male thread and the port-to-port dimensions are identical (460 × 198 mm); the PBG45 therefore fits directly onto the existing pipework, without adapters or modifications. Replacement is simply a matter of taking the old unit out and putting the new one in. This is a brazed plate heat exchanger with AISI 316L stainless steel plates, copper brazed, available from 30 to 150 plates. Choose the version with the same number of plates as your current TTG45H. In the table above you will find the matching replacement for each type number — the PBG45H-44, for example, corresponds to the APV SPX TTG45H-44-EE. Some versions are in stock in our warehouse in Oosterhout (the Netherlands); the others are available quickly on request. Would you like to know the delivery time or price of your version? Call +31 (0)162 429 068 or request a no-obligation quote; you will receive our price proposal within one working day.
