Our History

Cosmodyne began as a small military contractor specializing in the handling and storage of complex fluids. The company’s earliest line of cryogenic products included pumps, vaporizers, subcoolers, valves, and storage vessels.


Cosmodyne then entered the commercial industrial gas market with air separation plants of approximately 4 Tons/day and grew its product line to today’s 300 Tons/day liquefaction capability. ¬†Most recently, with the development of LNG as an alternative fuel, Cosmodyne ¬†has applied its extensive liquefaction know-how to develop a line of natural gas liquefaction plants.


Cosmodyne has delivered plants to every continent and has become a key supplier to the major industrial gas companies, utilities and alternative fuels suppliers.
