Australian-based company Domnick Hunter has developed a new generation of nitrogen gas generators for high volume users of nitrogen in operations involving lasers, furnaces, metal cutting and heat treatment operations.
The generators are said to produce nitrogen gas from compressed air at efficiencies that lower costs by up to 90 percent in different applications. The generators use Pressure Swing Adsorption (PSA) technology to separate nitrogen molecules from normal compressed air for applications including annealing, electronics and electrical manufacturing furnace blanketing, pipeline testing and welding.
The technology is already used in metals industries, one recent cost-saving application involved a producer of copper wire used in the repair of the winding of electric industrial motors, alternators and transformers. It is said that the new nitrogen gas generators now being introduced to Australia give high levels of performance, producing quality nitrogen gas with purities up to 10ppm as standard.
The system can be set to supply nitrogen at purities from 95 to 99.999 percent, and new features include equalization technology and a user-friendly interface.
