Sun Lung’s commitment to provide the best for its customers has been recognized with the latest Taiwan Excellence Award it received for its PCM Air-Cooling Gearbox. The system applies the Natural Air Cooling Principle. It consists of an exhaust fan installed on the rotating shaft, connecting with a copper spiral tube which is immersed into the inner PCM (Phase Change Materials) box installed at the bottom of the gearbox.
As the fan drives, the outside air can be absorbed into the inside tube constantly. The oil heat will be absorbed by the inner PCM, causing the Heat Exchange Effect with the cool air that can significantly lower the gearbox temperature. The cooling efficiency can be upgraded by 30%.
The exchanged hot air being led to the external water-coolant box can be transferred to normal evaporative emissions phase, avoiding the greenhouse effect.
This system can be widely used in many kinds of gearboxes for industries such as steel mills, power plants, cement factories, rubber and plastic machinery, recycling machinery, ships and other mechanical equipment.
Sun Lung was established in 1960 and specializes in designing and manufacturing precision gears and gearboxes for plastic extruders, plastic injection machines, blown molding/film machines, pipe/sheet/profile and recycling equipment. With high quality standards, innovative design and reliable customized service, more than 70% of Taiwan's plastic extrusion companies adopt and use Sun Lung gearboxes.
The company is not only a CE and ISO 9001-certified company, but also a member of AGMA (American Gear Manufacturers Association) & TAMI (Taiwan Association of Machinery Industry). From 2000 to 2012, the company has distributed more than 20,000 gearboxes in the global market. The company has won many local and international awards and recognitions.
