Like the SWEP B12, the UNEX PBF10 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.
