[INQ. NO. 1510M05] DHP was the first and the best Plate Heat Exchanger Company in Korea since its establishment in 1978.But now, it is rising as the best plate heat exchanger company in the world.

Plate-heat-exchanger DHP’s plate heat exchangers have a more than 100-year history and its structure is composed of a fi xed frame, a movable frame and corrugated plates which are in-between the two frames. Hot liquid and cold liquid are poured between the corrugated plates in turn. To prevent leaking, gaskets are mounted around the plates and tightening bolts are used to put 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 reduces 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. | Blog Magazine of korean-machinery, brands and Goods
