Oxidation protection for textile dyes

Oxidation protection for textile dyes
Various substances can react with oxygen rendering them unusable, and amongst these are dyes for the textile dying industries. In order to protect these dyes against oxidation, their supply tanks must be continuously exposed to a nitrogen overpressure. The nitrogen is provided in compressed gas cylinders. An automatic changeover system ensures that the plant changes over to another filled cylinder before the previous one is fully emptied.
