The D/G series high efficiency air cooler is high efficient heat-exchanging device which uses new design, new material and new technology, having the advantage of light weight, long durability and high eficiency compared with products of the same kind. Imported production line is empolyed to manufacture wholly rippled fins of advanced design which can keep high heat-exchanging rate even during frosting. The coil unit which consists of heat-exchanging tubes and fins is fully hot-dip galvanized. It has the advantages of high heat exchanging efficiency, small hot resistance,good corrosion resisting property and quick defrosting. The fan selected is high efficiency, low noise outer rotor axial flow fan. It has the advanctages of big air flow, low power, and long delivering distance. Casing surface employs rust-proof stoving finish and plastic spraying techniques to achieve corrosion resistance, beautiful and clean appearance, and good removablity.
