APPLICATION

Alfa Laval’s TS6 gaskets plate-and-frame heat exchanger is designed to heat water or CIP solutions by means of steam. It also performs general heating and cooling duties.

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, resulting in 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 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 positioned with 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 plate.
