The heat exchangers below are 1:1 replacements for the GEA M25

Brazed plate heat exchangers such as the GEA M25 are widely used in heating and domestic hot water installations. If your M25 fails, you replace it 1:1 with the UNEX PBG20: the port-to-port dimensions are identical (476 × 69 mm) and the connections correspond — 22.35 mm solder or G1" male thread (combi connection: both usable). Each port can thus be soldered as well as screwed, and the pipework stays as it is. The PBG20 has plates of AISI 316L stainless steel, copper brazed. For the M25 series, versions from 30 to 80 plates are available; take over the plate count of your current exchanger. The GEA M25-40, for example, is replaced by the PBG20M-40. Some versions are in stock in our warehouse in Oosterhout (the Netherlands); the other sizes are quickly delivered on request — so you are not tied to the lead times of the original supplier.
