|
Mixtures of Nitrogen with other gases in defined compositions, e.g. Synthetic air (20% O2 80% N2), Synthetic air HC-free (20% O2 80% N2). Nitrogen is also available cryogenically liquefied, in road tankers or from nitrogen service vehicles in the case of low requirements from 5 to 300 l. In this case the technical equipment required is provided by Linde. The LI-PUR® system satisfies even the most stringent demands.
