Read the number of plates from the nameplate of your GEA WTT GBS300H and choose the UNEX PB5 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 PB5 is copper-brazed with stainless steel plates.
