Gas Mixing Systems

Gastech Gas Mixer is based on the principle that a constant upstream pressure and a constant pressure drop across a fixed flow resistance results in a constant flow rate. The two adjustable orifices in the needle valves provided in the system, with their respective built-in flow resistances assure constant flow of individual gases in the desired proportion independent of the downstream pressure.

The upstream pressures are controlled by the respective pressure regulators.

The individual flows are engineered such that when mixed together, a mixture of the desired proportion is produced.

The mixing takes place at low enough pressures and in such a manner that a completely homogeneous mixture is formed without leaving any pockets of individual pure gases.

In Gastech Gas Mixer practically unlimited turndown is achieved as far as the outlet flow rate is concerned for the entire system through a pressure switch, solenoid valve.

The frequency of the solenoid valve remaining open is increased as the process demand for the gas mixture increases.

THE QUALITY OF THE GAS MIXTURE REMAINS UNAFFECTED AT VARYING OUTLET MIXTURE FLOW RATES.
