Liquid Air Backpack

Project Info

Project Description

Iron Ring personnel assisted in the design, development, and testing of a sub-critical cryogenic liquid air backpack for use by first responders and Haz-Mat operations. A key benefit of this technology is to use the heat capacity of the cryogenic air to provide whole-body cooling to the user through the use of a water/cryogen heat exchanger. The design has evolved and been adapted by NASA for use in simulated Martian space suit evaluations in the US desert Southwest.
