How Does A Plate To Plate Heat Exchanger Work

The gasketed plate heat exchanger consists of formed chevron plates of corrosion resistant metals.Every other plate is reversed so the ridges of the herringbone pattern intersect one another on adjacent plats forming a lattice of contact points.The plates have an elastomer gasket that is contained in a formed groove to seal the fluid between the plates.The plates with gaskets are then installed in a pressure retaining frame and compressed to form two separate systems of channels for two media to flow in a counter current direction.The lattice structure causes vigorous turbulence, thus,ensuring maximum heat transfer.

The frame is made up of thick steel pressure retaining parts.the fixed cover and the movable cover,that when pulled together with the tightening bolts form the pressure retaining structure for the plates/plate pack.The carrying bar and guide bar act as a carrier and guide to both the plates and the movable cover.

Frames come in two different materials.Depending on your application, the plate heat exchanger frame can be either stainless steel or powder coated mild steel.
