Equipment that can be added to the basic air stripper includes an air heater to improve removal efficiencies and automated control systems with sump level switches and safety features, such as differential pressure monitors, high sump level switches, and explosion - proof components.
  • Synthesis of a system for monitoring oxygen concentration in working area air
    where D is the inner diameter of the delivery tubes; L1, L2 are the lengths of the delivery tubes (between the measurement points and the gas analyzers); and V is the volume flow rate of the air flow booster. .... The system having a measurement point switching device has only one electrochemical gas analyzer (Fig. 1c). .... As in the preceding case, the gas analyzer, sampling device, and measurement point switching device can be placed outside the explo- sion -risky areas and need not be of the explosion- proof makeup.
