Free flow models have wider flow channels that can handle fluids with particulate pulp or fibrous materials five times larger than other plate designs. Free flow models feature minimum metal-to-metal contact points between adjacent plates to reduce points for particles to catch.
Free flow models available in 2″ to 12″ connection sizes.
Plate and Frame heat exchangers use a combination of gasketed chevron-style heat transfer plates sequenced inside a frame. The heat transfer plates have holes at the four corners forming a header that distribute the respective flows to the opposite sides of each plate in a countercurrent flow pattern. The fluids are confined to the heat transfer surface of the plate or the port as appropriate with elastomer gaskets. The high heat transfer rate, due to the chevron plates, and countercurrent flow pattern allow Plateflow to perform with one-third to one-fifth the surface area of a shell and tube heat exchanger.
All of Standard Xchange’s Plateflow are to ASME Section VIII Division 1 with U stamp. Other codes available upon request.
Materials: 304, 316 Stainless Steel and Titanium Plates. Gaskets in Nitrile or EPDM. Other materials available upon request.
Applications: Free Flow feature is ideal for heat reclamation in pulp and paper or ethanol/biodiesel processes where wash water, white water, mash or other high fiber or coarse fiber fluids are used.
