Zero Air Generator for TOC Analyzer produces a continuous flow of
high purity Zero Air at selected pressure.

• Compressor takes the air from atmosphere, the hot air is than passed
through copper cooling coil.

• The cool air is than passed through furnace where hydrocarbons are
cracked at high temperature (temp. range – 400°C to 500°C) in presence
of catalyst. The furnace reaction at higher temperature breaks the
hydrocarbon into CO2 & H2O.

• Water is drained away through 5p & 0.01p filter. The modular pressure
swing adsorption unit operates with alternating pressure increase and
decrease. Untreated 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 of
required purity.
