Replacing the Reflex RHC40 with the UNEX PBU11

Replacing a Reflex RHC40 with the UNEX PBU11 is a straight swap: port centres and connections are identical, so the existing pipes stay exactly where they are.

  • Port centres

    281 × 72 mm

  • Connections

    G1" external thread

  • Number of plates

    10 to 70 plates, 7 versions

  • Stock

    7 of 7 versions in stock

Like the Reflex RHC40, the UNEX PBU11 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 Reflex RHC40

Will the UNEX PBU11 fit my Reflex RHC40 without modifications?

Yes. The replacement has the same port-to-port dimensions (281 × 72 mm) and the same connections (G1" external thread), so the existing pipework does not need to be modified.

Is the replacement for the Reflex RHC40 available from stock?

7 of the 7 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 70 plates, in 7 versions. Choose the version with the same plate count as your current Reflex RHC40.
