M3 M3-FG PED Plate heat exchanger Applications General heating and cooling duties. Heating by means of steam. Standard design The plate heat exchanger consists of a pack of corrugated metal plates with portholes for the passage of the two fluids between which heat transfer will take place. The plate pack is assembled between a fix frame plate and a movable pressure plate and compressed by tightening bolts. The plates are fitted with a gasket which seals the interplate channel and directs the fluids into alternate channels. The number of plates is determined by the flow rate, physical properties of the fluids, pressure drop and temperature program. The plate corrugations promote fluid turbulence and support the plates against differential pressure. The plate and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar, both of which are fixed to a support column. Connections are located in the frame plate or, if either or both fluids make more than a single pass within the unit, in the frame and pressure plates. Typical capacities Liquid flow rate Up to 4 kg/s (60 gpm), depending on media, permitted pressure drop and temperature program. Water heating by steam 50 to 250 kW Plate types M3 and M3-X, where M3 provides parallel and M3-X diagonal flow (see figures on the next page). M3D, double wall plates. Frame types FG
