Replacing the APV SPX APV OHC60 with the UNEX PBU20

Is there a APV SPX APV OHC60 in your installation that leaks or is losing capacity? The UNEX PBU20 takes its place without any change to the pipework.

  • Port centres

    479 × 72 mm

  • Connections

    G1" external thread or G5/4" external thread

  • Number of plates

    10 to 100 plates, 26 versions

  • Stock

    22 of 26 versions in stock

Like the APV SPX APV OHC60, the UNEX PBU20 is a brazed plate heat exchanger: stainless steel plates brazed together with copper, so no gaskets and compact. The table above shows the matching version for each type number — keep the number of plates of your current unit and the replacement fits exactly.

Matching insulation, brackets and connection sets can be ordered directly on the product page. Not sure which version you need? Send us the type or a photo of the nameplate via the contact form and you will receive a no-obligation quote within one working day.

Frequently asked questions about replacing the APV SPX APV OHC60

Will the UNEX PBU20 fit my APV SPX APV OHC60 without modifications?

Yes. The replacement has the same port-to-port dimensions (479 × 72 mm) and the same connections (G1" external thread, G5/4" external thread), so the existing pipework does not need to be modified.

Is the replacement for the APV SPX APV OHC60 available from stock?

22 of the 26 versions are in stock in our warehouse in Oosterhout, the Netherlands, and are delivered quickly. The other versions are available on request.

Which plate counts are available?

The replacements are available from 10 to 100 plates, in 26 versions. Choose the version with the same plate count as your current APV SPX APV OHC60.
