Zero Air ( O' Air)

ZERO AIR

Zero Air is tasteless, odourless, colourless and non-flammable gas though it might help in burning due to the presence of high contents of Oxygen in it. The main difference between Atmospheric Air and Zero air is that Zero Air contains much lesser impurity contents of water vapor and Hydrocarbons than Atmospheric air. Applications where impurities like Moisture or Hydrocarbons are not desired, such applications make use of Zero Air or Dry Air. Zero Air is produced by mixing of Pure Nitrogen and Pure Oxygen in a controlled quantity composition and under controlled atmosphere. This mixing technique requires high degree of expertise to provide a good quality Zero Air/Dry Air to make it free from moisture and Hydrocarbons.

As a source of oxygen, air is essential for combustion, respiration, decay and various industrial processes – including oxidation. Some of these applications call for extremely high levels of purity. As regular ambient air contains a number of impurities, synthetic air is the preferred choice for these applications. This is produced by mixing pure oxygen (21%) with pure nitrogen (79%).

For some applications where continuous and high quantity of Zero Air is required to be feed, We make use of Zero Air cylinder quad which is nothing but number of cylinder interconnected and having common outlet.

Zero Air is sometimes referred as Dry Air (because it has got much lesser content of water vapor when compared to Atmospheric Air) and also Synthetic Air (because it is manmade). Zero air is an essential need of many laboratories and research centers in which it is used for various electronic instruments like GC (Gas Chromatograph). A good quality Zero Air having very low or almost negligible water and hydrocarbon content, improves the life of FID detector. We have in house laboratory equipments to check the level of purity as well as various impurities present in it.

Industrial Applications

In Gas Chromatography for FID detector as a Flame Gas.

In Gas Chromatography for FPD detector as a Flame Gas.

In Gas Chromatography for AED detector as a Dry Air Purge Gas.

In Emission analyzers to calibrate and check various impurities of Hydrocarbons.

In various other chemical analysis and process control applications
