D Series

Double Wall BPHE

To prevent two different kinds of fluid from intermixing caused by internal leakage, KAORI precisely designed D Series solution with the double-stacked plates, eliminating the possibility of cross contamination.
The unique air gap is created between the two plates. Once internal leakage occurs, the 2nd plate becomes a shield to keep fluid stay and flow on the same channel through the air gap. Meanwhile, vent holes outside the plate will seep out fluid as an indication of leakage.
