Double wall units reduce the possibility of fluids intermixing due to a plate failure. Two plates are pressed together to ensure a tight fit to minimize heat transfer losses while maintaining a leak path for detection in case of plate failure.
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.
