Eight advantages of air compressor waste heat recovery device

During the operation of the air compressor, about 80% of the input electric energy will become heat, and the remaining 20% ​​will eventually become compressed air energy. After the electric energy consumed by the compressor is converted into heat in the working process, most of it is taken away by the compressed special mixture
