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 hydrocarbons are cracked at high temperature (temp. range 300°C to 400°C) in presence of catalyst. The furnace reaction at higher temperature breaks the hydrocarbon into CO2 & H2O
  • Water is drained away through 5μ & 0.015μ filter
  • The modular pressure swing adsorption (PSA) unit operates with alternating pressure increase and decrease
  • Air flows under pressure through the reaction towers containing molecular sieve adsorber
  • Moisture, CO, CO2, THC and other unwanted components in the air are adsorbed, leaving Zero Air Gas
  • The Zero Air Generators are suitable for use in laboratories and industrial environments.
