Double wave plate heat exchanger is an innovative product that maximizes heat transfer by incorporaiing tiny corrugation into the heat plate ot the existing corrugated heat plate. It consists of cooling heat plate formed with high efficiency micro thin plate. It utilizes only the advantages of open type and closed type. It requires smaller space as it has maximized heat transfer per unit volume. It is 20% more efficient than single wave type as it limits fouling and facilitates the formation ot warm current due to tiny corrugation Structure.
