The air to air plate heat exchanger uses corrugated metal plates as the heat transfer element and the welding process to seal it, which greatly improves the safety and reliability of the heat exchanger, has high heat transfer coefficient, low pressure, small footprint, etc. It is a new type of efficient heat transfer equipment. Especially for gas - gas heat transfer of the all-welded plate heat exchanger, is currently more advanced energy efficient gas preheater, with high heat transfer efficiency, good sealing performance, pressure reduction, compact structure, corrosion resistance, long life, not easy to accumulate dust, easy to clean and so on. At present, the gas-gas all-welded plate heat exchanger is increasingly used in various industrial furnace combustion air preheating, gas preheating.
All-welded plate heat exchanger is a kind of universal heat transfer equipment, suitable for a variety of liquid-liquid heat exchange, liquid-steam heat exchange, gas-gas heat exchange and other occasions, is water-water, water-steam, water-oil, gas-gas heat transfer of the ideal equipment, widely used in petroleum, chemical, electric power, metallurgy, food and other fields.
▲Water-water heat exchange: for heating or cooling of industrial or domestic water, such as central heating, domestic hot water, cooling of recycled water, etc..
▲Water-oil heat exchange: used for heating or cooling of industrial oils, such as hydraulic oil cooling, quenching oil cooling, engine oil cooling, etc..
▲Water-steam heat exchange: for heating or condensing steam for industrial or domestic use, such as process water heating, circulating water heating, etc..
▲Gas-gas heat exchange: Used for waste heat recovery of flue gas from various industrial furnaces, such as air preheater, gas preheater and so on.
