Applications

Purge Gas generators use sophisticated techniques of Pressure swing adsorption technology to purify purge gases from the compressed air. A typical purge gas generator works like this. First of all oil, water and the dust particles gets removed from the compressed air. Carbon dioxide is removed by pressure swing adsorption (PSA). The concentration of these compounds are reduced to CO₂ < 1 ppm, H₂O < 1 ppm. By removing CO₂ and H₂O the molecular sieve is regenerated automatically. This process is repeated continuously.

Features of Purge Gas Generators:

• Maximum air inlet temperature must be + 30 °C.
• Air that is used must have Oil content below 0,01 mg/m3, water content < - 40 °C dew point, dew point particles < 0,1 µm.
• Operating pressure can approximately range from 60 to 125 psig.

Advantages of Using Purge Gas Generators:

• Effectively eliminates unsafe and expensive gas cylinders.
• Protection of the beam splitter from corrosion by moisture.
• Channeling not needed.
• Safe and cost wise cheap.
• Works with low pressure.
• Delays get reduced in operation as the instrument is being purged.
• Low noise, the enclosure is sound insulated.

Applications of Purge Gas Generators:
There is wide range of applications for Purge gas Generator that includes Purge Gas utilized for Optics, sample Chambers, and Air Bearings. Accessories for FT-IR Spectrometers, continuous Emissions Monitors, Matrix GC’s, TOC Analyzers and Calibration Air for CO₂ Analyzers.
