Plate Type Air Preheater

Plate type air preheater is a kind of energy saving and environmental protection equipment. The main heat transfer element, ie. flat plate or corrugated plate are welded together or mechanically fixed to form plate pack. The modular design of the product makes the structure flexible. The unique AIR FILMTM technology solved the dew point corrosion. Air preheater is widely used in oil refinery, chemical, steel mill, power plant, etc.
