The benefits of the implementation of the screw air compressor heat recovery project for corporate customers

During the long-term continuous operation of the screw air compressor, electrical energy is converted into mechanical energy, and mechanical energy is converted into wind energy. In the process of converting mechanical energy into wind energy, the air is compressed by a strong high pressure, causing its temperature to rise sharply.
