Semi Welded Heat Exchanger - China

Why semi-welded type?

Gasketed plate heat exchanger reaches its limits when it comes to aggressive media for which the use of gaskets is not suitable.

We provide semi-welded plate heat exchanger in this circumstance.

It is widely used in the evaporation and condensation of ammonia and freon refrigerant, industrial evaporation and condensation, water-cooled oil cooler, and general cooling and heating of high temperature, high pressure and strong corrosive media in one channel.

Our semi-welded plate heat exchanger adopts the world's most advanced laser welding machine and modern laser beam welding process.

Compared with other welding methods, laser beam welding process has the advantages of little deformation after welding, high welding quality, and small stress.

It is particularly suitable for high pressure and corrosive conditions.

Working principle

Semi-welded plate heat exchanger consists of a series of cassettes, which formed by two plates laser welded together along the sealing groove.

The aggressive medium flows inside the cassette, only in contact with a special designed ring gasket.

Each cassette is fitted with a gasket.

The other medium flows in the gasketed channels.

Two media flow reversely in adjacent channels, between which heat transfer will take place.

Structure

Two main parts: cassettes and frame.

Cassette is the core component of semi-welded plate heat exchanger.

The frame consists of fix frame plate, movable pressure plate, carrying bar, guide bar, and thread rods.

Cassettes are assembled between a fixed frame and a movable pressure plate and compressed by tightening bolts.
