C21 Dri-Gas Sampling System

ATi’s C21 Dri-Gas Sampling System removes water vapor from the gas stream using a cold plate to condense the vapor and deliver a dry sample.

Dri-Gas sampling

Monitoring combustible or toxic gases in areas with condensing levels of moisture often results in premature sensor failure. Water condensing on sensor surfaces or within the sensor flame arrestor can be difficult to avoid due to widely variable ambient conditions. 

ATi developed a solution to this problem with a gas sampling system that also conditions the sample by removing water vapor. The Dri-Gas sampling system draws gas samples from high humidity vent stacks, ducts, wet wells, or other humid locations. The system removes water vapor from the gas sample by contact with a cold plate that condenses moisture and delivers a dehumidified gas sample suitable for toxic and combustible gas monitoring equipment. Excess condensate is pumped to a drain fitting on the bottom of the enclosure and can be collected if necessary.

Features & specification

  • Condensing water vapor removed continuously
  • Samples from ducts under vacuum
  • Gas sensor “blinding” eliminated
  • Virtually maintenance free
  • Options for 120 VAC or 230 VAC Operation
