NASA Selects Paragon for SBIR Phase II Award

Paragon Space Development Corporation will continue to developed an improved system to remove liquid condensation from the air for use on the International Space Station and future crewed vehicles beyond low Earth orbit under a NASA grant.

NASA has selected the Tuscon, Ariz.-based company for a Small Business Innovation Research (SBIR) Phase II award to continue work on the COndensate Separator for Microgravity Conditions (COSMIC) device. The contract is worth up to $750,000 over two years.

“COSMIC is applicable to ISS and all future NASA crewed systems including the Lunar Gateway,” the company said in its proposal summary. In addition to NASA crewed applications, COSMIC is applicable to future commercial crewed systems under development.

“COSMIC may also have a multitude of terrestrial applications in the humidification, evaporative cooling, oil and gas deliquidification, and other environmental control markets,” Paragon added. “These applications provide access to $10s millions annual revenue for licensed COSMIC derivatives.”

Technical Abstract

The Paragon COndensate Separator for Microgravity Conditions (COSMIC) is a full flow device that separates liquid condensate from air using an inertial process with low power draw, negligible pressure drop, and efficient condensate collection. COSMIC, and associated systems in development by Paragon, form a drop-in solution to replace the ISS Common Cabin Air Assembly (CCAA) Compact Heat Exchanger Slurper and Water Separator. On ISS, the Slurper bar suffers continued siloxane chemical degradation that modifies surface hydrophobicity, resulting in inadequate performance.

In Phase I Paragon used additive manufacturing and an adaptable test fixture to evaluate competing designs and demonstrate successful liquid/air separation far in excess of NASA performance requirements with the most favorable solution.

In Phase II, Paragon will optimize the design for on-orbit use and produce an integrated, low-weight, solution including optimized product water collection and delivery to the Water Processing Assembly.

Potential NASA Applications

On ISS, the Common Cabin Air Assembly (CCAA) Compact Heat Exchanger slurper bar suffers continued siloxane chemical degradation that modifies surface hydrophobicity, resulting in inadequate performance. Paragon’s COndensate Separator for Microgravity Conditions (COSMIC) is a drop-in solution to replace the Water Separator and Slurper using an inertial approach that is insensitive to chemical modification. COSMIC is applicable to ISS and all future NASA crewed systems including the Lunar Gateway.

Potential Non-NASA Applications

In addition to NASA crewed applications, COSMIC is applicable to future commercial crewed systems under development. COSMIC may also have a multitude of terrestrial applications in the humidification, evaporative cooling, oil and gas deliquidification, and other environmental control markets. These applications provide access to $10s millions annual revenue for licensed COSMIC derivatives.
