For more than 100 years, Praxair (a Linde company), has taken something as fundamental as air and turned it into ways to make plants operate cleaner and more productively, food taste better, breathing easier and manufacturing processes more efficient -- in short, to make all our lives better.
Praxair makes lighter than air and heavier than air gases available for practical applications. We produce and sell atmospheric gases (oxygen, nitrogen, argon, and rare gases), as well as process and specialty gases (CO 2, helium, and hydrogen), for the chemicals, food and beverage, semiconductor, and healthcare industries worldwide. Our Praxair Surface Technologies unit supplies high-temperature and corrosion-resistant metallic, ceramic, and powder coatings, mainly to the aircraft, plastics, and primary metals markets. Depending on a customer's needs, we can build an on-site gas plant or provide gases by the cylinder. – less
