Zero Air Generator for GC / TOC (Online / Offline)

Schematic Diagram of Zero Air Generator
  • Zero Air Generator produces a continuous flow of high purity Zero Air at selected pressure
  • For TOC Analyzer, compressor takes the air from atmosphere, the hot air is then passed through copper cooling coil
  • The cool air is then passed through furnace where hydrocarbonsare cracked at high temperature (temp. range 300°C to 400°C) inpresence of catalyst. The furnace reaction at higher temperaturebreaks the hydrocarbon into CO & H₂O
  • Water is drained away through 5μ & 0.01μ filter
  • The modular pressure swing adsorption (PSA) unit operates withalternating pressure increase and decrease.
  • Air flows under pressure through the reaction towers containing molecular sieve adsorber.
  • Moisture, CO, CO₂ , HC and other unwanted components in the air are adsorbed, leaving Zero Air Gas.
Salient Features :
  • Micro controller digital display
  • Deliver constant pressure & flow
  • Fully Automatic System
