Brazed plate heat exchangers such as the Funke GPL9 are widely used in heating, domestic hot water and cooling installations. If your GPL9 is reaching the end of its service life, the UNEX PB67 is the 1:1 alternative: identical port-to-port dimensions (690 × 161 mm) and a combi connection of G2½" male thread or 54 mm solder — one port, both connection methods usable. The PB67 has plates of AISI 316L stainless steel and is copper brazed. The series runs from 20 to 240 plates, ample to replace every GPL9 version with a unit of the same plate count. For a Funke GPL9-80, for example, the PB67H-80 is the matching replacement; the full mapping is shown in the table above. Replacement is thus limited to swapping the exchanger itself. The versions are quickly available on request from our warehouse in Oosterhout (the Netherlands). Request a no-obligation quote — you will receive a quotation within one working day — or call +31 (0)162 429 068 to determine the right version.

Frequently asked questions about replacing the Funke GPL9

Will the UNEX PB67 fit my Funke GPL9 without modifications?

Yes. The replacement has the same port-to-port dimensions (690 × 161 mm) and the same connections (54 mm solder, G2½" external thread), so the existing pipework does not need to be modified.

Is the replacement for the Funke GPL9 available from stock?

The versions are available on request; contact us for current lead times.

Which plate counts are available?

The replacements are available from 20 to 240 plates, in 17 versions. Choose the version with the same plate count as your current Funke GPL9.
