Zero Air Generator
The Zero Air Generator is suitable for gas chromatography. Ensuring
ultra high purity grade zero air for combustion gas, this type of generator
has a stable and lower baseline signal unlike traditional gas sources. Owing
to its lower baseline noise, there is larger signal to noise ratio,
enhancing the sensitivity or larger peak areas. The zero air generator is
easy to operate, with no labor intensive monitoring involved.

Operation of Nitrogen Generators
If the temperature of the
compressed air is more then 40ºC then it is necessary to provide AFTER
COOLER which should ensure the outlet temperature of 40ºC. During this
cooling process, some moisture condenses, which is removed from Prefilter.
The HEATLESS type Zero Air Generator is the simplest & economical Zero
Air Generator with Activated Alumina Molecular Sieve as the desiccant. The
Twin Absorbers filled with these desiccant is assembled with 3-way, 2-way,
control valves and interconnected pipings. The unit follows the Drying
sequences of 10 minutes. Here one absorber is under drying cycle for 5
minutes & simultaneously the other absorber under goes for regeneration
and equalization process for (4 + 1) 5 min. respectively. The changeover of
the absorber takes place with the help of sequence timer. The moistured air
and regenerative air is drained out through the individual silencer of the
absorbers provided at the bottom hence Zero Air comes from the top of the
Absorber & is taken to your process for your applications.
