Headquartered in Arizona with facilities in Denver and Houston, Paragon Space Development Corporation, an aerospace engineering and technology development company, designs and manufactures environmental controls for extreme and hazardous environments. The firm designs, builds, tests, and operates life support systems, including the design and manufacture of thermal control and life support systems for astronauts, contaminated water divers, and extreme environment adventurers, as well as for unmanned space and terrestrial applications. The firm offers a life support system built to meet or exceed NASA human flight safety standards; a diving system for the U.S. Navy; metabolic (heat regenerated) temperature swing adsorption systems for future lunar and Martian astronaut excursions; solid oxide electrolysis, an air revitalization system for use on the Moon, Mars, and in transit to other destinations; a potable waste water recycling system; and autonomous biological systems for maintaining experimental organisms used in microgravity life science experiments. The company also provides extruded, integral, and stagnating radiators; variable heat-load and external environment thermal control system for passive vehicle thermal control applications in the low earth orbit environments; SuperCool phase change heat sinks, which provide non-toxic and non-flammable thermal storage packs for portable life support systems and other applications; and integrated sublimator driven cold plates. In addition, Paragon offers high-precision tube bending and specialized welding services; and systems engineering, applied research and development, and environmental testing services.
