Semi-welded plate heat exchanger

Applications

Heating and cooling of aggressive media. Duties in refrigeration

installations.

Standard design

The plate heat exchanger consists of a pack of corrugated

metal plates with portholes for the passage of the two uids

between which heat transfer will take place.

The plate pack is assembled between a x frame plate and a

movable pressure plate and compressed by tightening bolts.

The semi-welded plates combine the exibility and service-

ability of the gasketed heat exchangers with the assurance

against leakage of the welded heat exchangers. In the plate

arrangement, every other channel is welded, and every other

channel is gasketed. The number of plates is determined by

the ow rate, physical properties of the uids, pressure drop

and temperature program. The plate corrugations promote

uid turbulence and support the plates against differential

pressure.

The semi-welded plate heat exchanger is provided with

gaskets specically designed to resist aggressive media.

The non-aggressive media ows in the gasketed channels.

This construction means that it can easily be dismantled, for

example for exchanging gaskets or for inspection and cleaning

of the gasketed channels.

Corrosion-resistant plate materials, the absence of pressure

retaining welds, double gasket seals, and a exible yet vibration

resistant design - to assure long life and trouble free operation.

The frame plate and the pressure plate are suspended from

an upper carrying bar and located by a lower guiding bar,

both of which are xed to a support column. Connections are

located in the frame plate or, if either or both uids make more

than a single pass within the unit, in the frame and pressure

plates.

Typical capacities

Liquid ow rate

Up to 16 kg/s, depending on media, permitted pressue drop

and temperature program.

M6-MW Semi-welded plate heat exchanger Applications Heating and cooling of aggressive media. Duties in refrigeration installations. 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.
PAGE 2
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.
