The Dri-Gas sampling system draws gas samples from high humidity vent stacks, ducts, wet wells, or other humid locations.
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 has 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.
Dri-Gas systems contain a diaphragm sampling pump with brushless DC motor providing operational life in excess of 10,000 hours. The pump is capable of pulling inlet line vacuum of up to 10” Hg. making it suitable for sampling duct system with negative pressures. The outlet of the pump is controlled by an adjustable rotameter allowing system sample flow to be set to the normal rate of 500 cc/min.
A differential pressure switch across the pump provides an alarm should the inlet line or outlet lines become blocked. An alarm lamp on the door provides local alarm indication and a SPDT alarm contact is available for remote alarm indication.
An optional inlet filter assembly is available for applications where gas streams may contain dust or debris that might cause problems in the air pump. A replaceable filter element on the end of the inlet assembly can be easily changed when necessary. A plugged inlet filter will be indicated by a fault indication. A package of filter elements are supplied with the inlet assembly.

Up until the 1800s, salmon were so plentiful in California that these “ bits of silver pulled out of the water ” could be observed ascending the waterways, thousands at a time, each season. However, decades of logging, the construction of dams, and other human interventions have changed the waterways of the state so significantly that the range of the salmon has been permanently altered. Now, a team of scientists collaborating through the Interagency Ecological Program have developed a plan to improve salmon management and, hopefully, help save the species. Team members from NOAA Fisheries, the California Department of Water Resources, the U.S. Fish and Wildlife Service, the California Department of Fish and Wildlife, the U.S. Bureau of Reclamation, and the U.S.Read More
Marine fouling species may seem to be lowly creatures, situated toward the bottom of that portion of the food chain animals comprise. However, these filter-feeding invertebrates that make their homes on hard underwater substrates such as the hulls of ships are among some of the most successful invasive species. Their secret is simply their ability to latch onto human vehicles and survive. Now, new research on the fouling community in the San Francisco Bay indicates that a single wet winter and the change in salinity that high levels of precipitation bring can knock back the advance of these hearty creatures. Marine biologist Andrew Chang of the Smithsonian Environmental Research Center’s Tiburon, California branch published this new research in December of 2017.Read More
Do you know what's in your water? How certain are you that it's safe? In mid-December 2017, researchers from across the United States specializing in various disciplines came together at the annual meeting of the Society for Risk Analysis to present reports on a range of problems in American water infrastructure. This plumbing safety research illuminates a disturbing litany of failures in water safety all over the country—but also highlights a commitment to fixing problems and taking a proactive approach to keeping water infrastructure safer. The Replacement Era In 2001, the American Water Works Association (AWWA) released a report entitled, “Dawn of the Replacement Era: Reinvesting in Drinking Water Infrastructure.Read More
