At Praxair, our experience in aerospace and aircraft development dates back over 100 years. Today, our industrial gases, services and supply systems allow our customers to meet environmental and safety standards, reduce operating costs, and most importantly, continue to push the boundaries.

We support rocket launch programs that are making commercial space travel a reality. For example, we develop wear-resistant coatings to help jet engines last longer and supply gases and liquids to testing facilities to make sure you get where you need to go safely. At Praxair, we work hard on the ground to help your business take off.


Automotive and Transportation

At Praxair, we help our customers produce high-quality parts and equipment at every step of the automotive and transportation manufacturing process. Because the quality of the finished product depends on what happens on the assembly line, it's essential to make precise, reproducible parts. Our supply of industrial gases, equipment and advanced applications make it easier to do just that.

As the oldest and largest producer of industrial gases in North America, we have the experience to meet the demands of our customers while respecting the needs of our planet. Our gases help create cleaner environments in automotive factories in areas such as wastewater treatment and solventless cleaning. Using our applications, we can help you reduce defects, limit downtime and lower emissions.


Chemicals

It's not just about the chemical; it's about the reaction — the combination of independent things to create something new and innovative. At Praxair, this way of thinking is exactly how we work with the chemical companies we serve. We don't just sell gases to you; we work with you to develop new methods for improving your processes, meeting your environmental goals and lowering your production costs. We have the expertise and experience to develop, implement and operate highly reliable and efficient supply systems, and we provide the industrial gases, services and applications that help you advance the production of your chemicals.


Diving

They say the oceans are the last frontier. At Praxair, we give you the gases, equipment and supply systems you need to explore the depths of those oceans worry-free. We developed the first breathing mixture tables in the 1920s and have been advancing the diving industry ever since. So whether you're diving for commercial or technical purposes, we are knowledgeable about which gases blend most effectively for the depths you're planning to travel. Our industrial gases meet stringent U.S. Coast Guard-approved and Canadian Standards Association-approved specifications, giving you the freedom to explore.

Glass

The action of making glass is over 5,000 years old, but two decades ago, Praxair made great strides in getting this ancient craft ready for the twenty-first century. With our full range of industrial gases, technologies and equipment, we successfully converted the first large container glass furnace to an oxy-fuel burner.

This development was good news not just for our customers, but also for the planet. Oxy-fuel melting improves glass quality and helps you save money by burning less fuel more efficiently. It also drastically reduces NOx emissions to help you meet today's regulatory requirements. Our burners allow you to produce a glass so clear and efficient that it could only be centuries in the making.


Healthcare

At Praxair, we take care of your needs so you can take care of your patients.
