Blanketing with Nitrogen

When storing highly volatile substances or substances prone to oxidation, safety and product preservation are of paramount importance. Blanketing with nitrogen is a safe and dependable method for constantly maintaining a protective layer of gas on top of the substance.

Humid air in the head space is replaced by high purity, inert and totally dry nitrogen. A precise valve control system ensures that as the tank is filled or emptied, the nitrogen content is automatically compensated to maintain the protective blanket. The result is safety, reliability and protection from degradation through oxidation.

For vessels often used in batch processes, characterized by cyclic filling and emptying, we have developed special inert gas sluices which prevent the entry of oxygen effectively.


The atmosphere within production areas - for example in reactors - can be efficiently and cost-effectively purged of oxygen and moisture at start-up or shut-down with nitrogen (GAN).

Filling and rinsing the processor with dry gas is fully controllable. No pumps are needed so the risk of sparks and ignitions, or cross contamination are eliminated.

What's more, the use of nitrogen ensures 'no reaction' either with the substance previously stored or with what is still to come.
