Second wind for 100-year-old technology


Hydraulic air compressor can slash cost of pneumatic power, cool deep mines and serve as a means of carbon capture


Hydraulic air compressor can slash cost of pneumatic power, cool deep mines and serve as a means of carbon capture.

A long-forgotten, century old technology for producing compressed air is one step closer to rebirth. On June 21, a who’s who of politicians and mining industry representatives came together for the official opening of a hydraulic air compressor demonstrator at Dynamic Earth, site of the Big Nickel in Sudbury.

Modeled on the Ragged Chutes hydraulic air compressor designed by Charles Havelock Taylor in 1905 to serve the pneumatic power needs of some 30 mines in the then-booming Cobalt mining camp in northeastern Ontario, the demonstrator will provide Sudbury-based Electrale Innovation Ltd. with the energy saving evidence it needs to commercialize the technology.

Air and water are mixed in a tank at the top of the hydraulic air compressor, or HAC, and sent down a pipe.
