Plate heat exchanger

[Serial No. 2012-B-100]

Since its establishment in 1978, DHP Engineering has solely devoted itself to manufacturing advanced models of plate heat exchanger and thus it could grow into the best company in the area in Korea. Based on such strides in the nation, now it is rising as one of the strongest leadership-holding companies in the world in the fields.

Composed of a fixed frame, a movable frame and corrugated plates that are inbetween the two frames, DHP Engineering’s plate heat exchanger boasts a more than 100-year lifespan. Between the corrugated plates, hot and cold liquids are poured in turn. To prevent leaking, gaskets are mounted around the plates and tightening bolts are used to seal the plates together. There is heat transfer between the two liquids through the plates. This is the main principle of a plate heat exchanger.

The arrangement of two liquids is that the cold liquid goes upward and hot liquid goes downwards in order to increase heat transfer efficiency. There is an advantage to use plate type heat exchangers over Shell & tube type heat exchangers; that is to say, the corrugations in the plates reduce the liquid turbulence to a low Reynolds number and the liquids flow is counter current so that the heat transfer efficiency is always 3~5 times higher than Shell & Tube type heat exchangers.
