With the simulation technology developing, BAVI gasketed plate heat exchangers have a wide application in the energy saving industry .BAVI gasketed plate heat exchanger consists of a pack of corrugated plates, which are compressed together between a fixed and a movable frame plate by tighten bolts so that they can be removed and are arranged between the upper and lower carrying bar.The carrying bars serve as a guide bar for the heat exchanger plates and form the connection between the frame plate and the support. Features with high heat transfer efficiency, cooling water saving, reliable operation, easy maintenance, lower installation,operation& maintenance cost, BAVI gasketed plate heat exchangers are gradually replacing the shell&Tube heat exchanger in many industries.
