Air Water has recently sold oxygen injector systems produced by Praxair to three electric arc furnace steel producers.
This marks the first sales since the two companies entered into a sales agency contract for Japan in December 2004.
The products involve an oxygen injector system developed with Praxair in house technology for use with electric furnaces, called the CoJet Gas Injection System.
The price of the system, minus installation costs come to about Â¥100m.
Although the amount of oxygen used increases by 10 percent, the three companies have judged that the advantage of increased production makes it worthwhile in comparison.
