Technical history
The beginning is always Kobelco
Since completing Japan's first domestic compressor in 1915, Kobelco has been proposing compressors that are one step ahead by accurately grasping the needs of the times. In 1956, the screw compressor became the first in Japan and continues to the present day. It inherits the refined technology, the recognized quality, and the unchanging spirit of pioneering.
