The oxygen adsorber model ISO2 98 is based on the principle of pressure swing adsorption. It mainly consists of two beds of activated carbon - one for adsorption and the other for regeneration - that hold the oxygen, thus separating it from the nitrogen.

OPERATION

Compressed air is initially sent by a compressor through a dryer to be dried and then routed alternately via pneumatic valves to the two adsorption beds. In this manner, while one bed is in adsorption phase, the other regenerates. The adsorbed oxygen is expelled to the exterior and the cells under controlled atmosphere are filled with inert nitrogen.

ADVANTAGES

The concentration of adsorbed oxygen can reach very high levels (from 95% to 99,9%) and output at low cost. Concentration is automatically and continuously monitored by an analyser and can also be preset by the operator. The inert gas generated is completely free of pollutants, and the residual oxygen can be used in the curing cells at concentrations of about 30-35%.

TECHNICAL CHARACTERISTICS

Nitrogen output: from 30 to 150 m3/h.
Nitrogen concentration: from 95% to 99%.
