Linde makes and sells industrial gases and the equipment and services that go with them. It says it is the largest industrial gas company worldwide. Its main products are the gases in air (oxygen, nitrogen, argon and rare gases) and process gases such as hydrogen, helium, carbon dioxide and specialty gases. Customers are in health care, chemicals and energy, manufacturing, metals and mining, food and beverage, and electronics. Linde is an Irish company with principal offices in the United Kingdom and the United States.
Linde delivers gases in three ways. On-site supply sends gas by pipeline from a plant next to a large customer. Merchant supply delivers liquid gas in bulk, usually under three- to seven-year contracts. Packaged supply fills metal cylinders for customers who need small amounts. The company picks the method that meets a customer's needs at the lowest cost.
Linde also has an engineering business that designs and builds plants for air separation, hydrogen, synthesis gas, olefins and natural gas. Its sales were $33,986 million in 2025, and approximately 64% of them were outside the United States. At the end of 2025 it had 65,177 employees worldwide.
