Praxair, Inc. is a large international industrial gases company. Praxair supplies atmospheric, process, and specialty gases as well as high-performance coatings and related services. It is the largest industrial gases company in North and South America and one of the largest worldwide[citation needed]; Praxair does business in more than 50 countries and has approximately 4,000 patents. Praxair serves a wide range of industries including metals, health care, food & beverage, energy, aerospace, chemicals, electronics, manufacturing, and others.


Headquartered in Danbury, Connecticut, the company was originally founded in 1907. Praxair was the first company in North America to commercialize cryogenically separated oxygen.[citation needed] The company introduced the first distribution system for liquid gas in 1917 and developed on-site gas supply in the 1940s.[citation needed] In the 1960s, Praxair introduced non-cryogenic means of air separation.[citation needed]

The company is present in different locations in the world. In South America it is known as White Martins. In China and India it is among the largest industrial gases manufacturer present. Praxair is also well established in Europe.

Praxair adopted its name from the Greek word "praxis", or practical application, and "air", its primary raw material.[citation needed]
