Abstract : An unmanned study of a carbon dioxide scrubber in a standard U.S. Navy two-lock recompression chamber is presented. Tests were conducted at the Navy Experimental Diving Unit to determine canister air flows and durations at various depths and initial carbon dioxide concentrations, using a Kinergetics, Incorporated Scrubber, Model DH-10. Air flows were 262 LPM, 274 LPM, and 270 LPM, at 15 FWS, 30 FSW, and 60 FSW respectively. For the canister duration studies an initial load of carbon dioxide was introduced into the chamber, then carbon dioxide was added to the chamber at a rate of 2 standard liters per minute to simulate 3 human occupants. Canister durations under steady state conditions of a long treatment were estimated to be 3.46 hours at 30 FSW, 1.89 hours at 60 FSW, and 1.16 hours at 165 FSW. (Author)
