Replacing the APV SPX APV OHC35 with the UNEX PBU11
Is there a APV SPX APV OHC35 in your installation that leaks or is losing capacity? The UNEX PBU11 takes its place without any change to the pipework.

Read the number of plates from the nameplate of your APV SPX APV OHC35 and choose the UNEX PBU11 with the same number in the table above. That version has the same length and comparable capacity; more plates means more capacity but also a longer unit. The UNEX PBU11 is copper-brazed with stainless steel plates.
Want to be certain you pick the right version? Send us the type number or a photo of the nameplate via the contact form. Our specialists check the dimensions and send a no-obligation quote within one working day, including insulation and mounting materials if required.
