The metals refining industry consumes significant quantities of industrial gases and is a sector on which traditional high margin liquid gas suppliers capitalize.

Gas At Site has a comprehensive range of robust on-site gas generators that reliably service even the most demanding applications. These can include bright annealing, carburizing, brazing, sintering, vacuum processing, sparging; gas purging and quenching. The aluminium industry in particular uses large quantities of nitrogen. Gas At Site can advise on process optimisation right through from melting and dross handling to refining, extrusion and annealing.

Different processes require different levels of gas purity. Do not be misled by a ‘one spec suits all’ approach if this is set at the default high purity level of liquid nitrogen. Liquid nitrogen, by nature of its energy intensive manufacturing process, is almost always sold at 99.999% purity regardless.

A compelling benefit of On-Site Gas generation is that purity levels can be controlled as appropriate thereby improving efficiencies and lowering process costs - in some cases up to 30% or more.
