The heat energy caused by recycle air compressor reduce waste pollution, protect environment, reduce energy loss and operation cost. OSG is specialized in saving heat energy development, and adapts interception process cross dressing technology, and developed special screw air compressor heat energy utilization device to exchange heat energy produced by high temperature and high pressure of air compressor and cool down which can make the company acquire the heat water for production and life. In the winter, it can be achieved above 55? and 65? in summer and autumn. It can make the company invest once and change the waste into the treasure, scientifically use energy, save high life and production heat water operation cost.
