R&D, Production and Sales Base

Our parent company Beijing Aerospace Propulsion Institute (CASC) was founded by 1958, which was the first research unit in China and involved in liquid propellant rocket engine development. Since 1984, CASC started to apply aerospace techniques to the industrial products development. The products have been successful developed such as thermal engineering equipments, special pumps, special valves, petrochemical equipments, measurement and control systems, environment protection systems for petrochemical and environment protection industries. Most of them filled the domestic gap and enter the international market successfully.
