Carbon Dioxide Absorbent Canister Studies of the Hot Water Heated, Helium-Oxygen Mode, MK 12 Surface Supplied Diving System.

Abstract

Testing of previous prototype MK 12 SSDS carbon dioxide absorbent canisters indicated that initial cooling of exhaled gas with subsequent gas rewarming within the CO2 absorbent bed led to drying of the absorbent material and deterioration in performance. The first two prototypes tested in manned dives had shorter CO2 scrubbing durations than desired. The recirculator assembly was modified by incorporation of two moisture retaining condensors within the body of the canister and hot water heating of the canister. Three canister studies were performed in 40 F water at 390 feet of seawater.
