The fans of our company are mainly used for the B/F413F, B/F513F air-cooled diesel engine and BF (4) 6M water-cooled diesel engines, as well as armored vehicles power module cooling system. By combining the German technology and our own technical characteristics, we have developed and produced WR202, WR203, WR205, WR206, WR212, such as a series of air-cooled fans and WR280 water-cooled fans. In addition, we developed independently WR209, WR210, WR211, WR213, WR215, WR216, WR217, WR218, WR219, WR240, WR260, and WR270 as series of power module cooling fans. The fans can be divided for two kinds, aspirated and exhausted. The aspirated fans can directly provide cooling air to the engines; the exhausted fans put heat of the power module into the atmosphere. The fans’ speed ranges from 1400r/min ~ 6000r/min. Our company has a fan history with twenty-odd years. The fan performance is stable and the quality reliable. Auxiliary diesel engines are exported to Bangladesh, Oman, Jordan, India and other countries, partly exported to Germany. The product once won the Hunan Province Technology Progress Award.
