Read the number of plates from the nameplate of your Danfoss XB37H and choose the UNEX PBF20 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 PBF20 is copper-brazed with stainless steel plates.
