Alfa Laval M Series Heat Exchanger

Central States Industrial (CSI) offers Alfa Laval's M Series plate heat exchangers as an efficient solution for general heating and cooling duties in hygienic applications. This range of heat exchangers is used in the same hygienic applications as the BaseLine range, but the M Series is selected when higher design pressure or extra-long plate packs are required. 

M series are standard heat exchangers used in dairy, food, beverage, and other hygienic applications. They are competitive choices for hygienic processes and utility applications.

Working Principle

Channels are formed between the plates, and the corner ports are arranged so that the two media flow through alternate channels. The heat is transferred through the plate between the channels, and complete counter-current flow is created for highest possible efficiency. The corrugation of the plates provides the passage between the plates, supports each plate against the adjacent one, and enhances the turbulence to bring you efficient heat transfer.

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 fixed-frame plate and a movable pressure plate and compressed by tightening bolts. The plates are fitted with a gasket that 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 fixed between the upper bar and lower 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.
