Nitrogen PSA demand set to increase


Whilst the flow for nitrogen pressure swing adsorption (PSA) in the areas of reflow soldering and laser processing is declining, the market for nitrogen generators for use on transportation tankers looks set to rise steadily.

Taiyo Nippon Sanso Corporation (TNSC) anticipates sales of Y900m, with sales of 22 nitrogen PSA units in this area alone.

Two of TNSC’s competitors, Kuraray Chemical and Air Water, are developing strategies to capitalise on this growing market and secure sales streams from potential clients, adding specialised equipment for these tankers to their existing product portfolio.
