ASTM A106 Seamless Carbon Steel Tube for Construction Boiler Machining Heat Exchanger Fluid Transfer
Air heat exchanger is a kind of heat exchanger that is used to cool or heat forcibly flowing air with water, glycol solution, steam or heat conduction oil as the medium. It is extensively applied in hot air heating, drying, cooling, dehumidifying and other works in such industries as light industry, building, chemical engineering, machinery, textile, printing & dyeing, electronics, food, starch, medication, metallurgy and painting. Different models of heat exchanger should be selected according to the actual working conditions.
