Since pilots have had the need to breathe at high altitudes, Carleton Life Support Systems Inc. has been there for them, providing oxygen enriched air and committing to the safety of their mission.
Carleton Life Support Systems is a world leader in the application of air separation technology for aviation applications and in the design and manufacture of miniature sterling cycle cryogenic coolers. Bendix Aviation founded the company in 1951 and the sold the facility to Litton Industries in 1982. Northrop Grumman Corporation acquired Litton Industries in 2001 and then in August 2003, divested the Life Support division, based in Davenport, IA, to Cobham plc, Dorsett, United Kingdom. Carleton Life Support is now part of the Carleton Technologies family of companies owned by Cobham.
Since its inception, Carleton Life Support has continually challenged its employees by encouraging forward thinking and maintaining its leadership role in advanced technology for military and commercial products. Life Support has developed an attention for details and prides itself on its rich history and reputation for excellence. Today, that persistence and innovation has transformed Carleton Life Support into a world-class operation that is on the forefront of superior new technology and continued market leadership.
