Plate Heat He at Exc Exc hang han g er M 3 S t a nd nd a r d d e s i g n 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 frame plate and a pressure plate and compressed by tightening bolts. The plates are fitted with a gasket which seals the channel and directs the fluids into alternate channels. The number of the plates are 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 plates and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar both of which are fixed to the support columns. Connections are located in the frame cover, or if either or both fluids make more than a single pass within the unit, in the frame and pressure plates. M3-FM
Plates can be obtained in all pressable materials. Gaskets are available in a wide range of elastomers.

Flow principle of an M3 plate heat exchanger
P la la t e t y p e s M3 and M3-X, where M3 provides parallel and M3-X diagonal flow (see figures).
Fr a m e t y p e s FM, FGL and FG.
W o r k i n g p r in i n c i p le le Channels are formed between the plates and corner ports are arranged so that the two media flow through alternate channels. The heat is transferred through the thin plate between the channels, and complete counter current flow is created for highest possible efficiency. No intermixing of the media or leakage to the surroundings will take place as gaskets around the edges of the plates seal the unit. The corrugation of the plates provides a suitable passage between the plates, support of each plate against the adjacent one and a strong turbulence resulting in maximum heat transfer t ransfer efficiency. efficiency.
