Gasketed Plate Heat Exchanger
Plate and frame heat exchanger is composed of corrugated metal plates sealed by gaskets and compressed inside a frame by tie rods with locking nuts. The port holes form continuous channels so the two fluids flow in countercurrent between the heat transfer plates, delivering high heat transfer coefficient, low fouling resistance, compact footprint, convenient maintenance and cleaning, small end approach temperature, and light overall weight.
Product Details
What is a gasketed plate heat exchanger?
A gasketed plate heat exchanger is built from corrugated metal heat transfer plates sealed by gaskets and clamped together within a frame. The plate port holes form continuous channels that distribute hot and cold media into alternating passages, where the two fluids flow in countercurrent to achieve efficient heat transfer.
Why choose this plate and frame design?
Compared with conventional shell and tube equipment, this design offers a much higher heat transfer coefficient, lower fouling factor, smaller end approach temperature, lighter weight, and a significantly smaller footprint. The modular plate pack also makes capacity adjustment, inspection, maintenance, and cleaning more convenient.
How is it designed and manufactured?
The heat transfer plate is the core element and is developed with CAD, CFD, CAE, and CAM tools to optimize plate geometry, sealing, and pressure resistance. During engineering, the required duty, flow rate, temperature program, pressure drop, plate pattern, materials, pass arrangement, and gasket selection are defined first, then the frame, nozzles, and plate pack are manufactured and assembled before pressure, leak, and performance testing.
