Combining the shipbuilding process which has the characteristics of high cocentration of exhaust air but low exhaust wind speed,Greentec has developed the High wind volume low conventration organic exhaust purification technology(HWVLCOEPT). The HWVLCOEPT has successfully applied in severial national key projects and military engineering projects with its high efficient but low maintaining cost.

The picture shows the shipbuilding base of Dalian New Ship Heavy Industry Co.,Ltd,which adopted Greentec LCOVWCEP to solve its exhaust problems. The LCOVWCEP technique has elected as the state key environmental protection practical technology in 2006.
