Environmental Control Unit for Damage Control Suit System
1972
Orner, George M. | Audet, Norman F.
The Navy Clothing and Textile Research Unit (NCTRU) has developed an Environmental Control Unit (ECU) for a life support system which was designed primarily for shipboard operations, such as damage control, rescue, and engineroom use, particularly during shutdown periods. The purpose of the ECU is to control the environment within a fully enclosed, impermeable Damage Control Suit (DCS). This ECU uses wet ice in finned canisters for cooling purposes. Closed circuit, forced ventilation is effected with a battery powered fan. An easily replaceable chemical pack containing lithium hydroxide and potassium superoxide provides for carbon dioxide removal and replenishment of oxygen. A highly efficient oxygen-sensing warning device constantly monitors oxygen level within the suit.
