Replacing the GEA WTT GBS525H with the UNEX PBU20
Replacing a GEA WTT GBS525H with the UNEX PBU20 is a straight swap: port centres and connections are identical, so the existing pipes stay exactly where they are.

Read the number of plates from the nameplate of your GEA WTT GBS525H and choose the UNEX PBU20 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 PBU20 is copper-brazed with stainless steel plates.
