Calea generated revenue in the 2011 financial year of €28 million with around 200 employees. The transaction is expected to be completed at the beginning of 2013.

Calea will complement the European homecare operations acquired by Linde from Air Products earlier in the year. Homecare comprises respiratory services such as oxygen therapy, sleep therapy and ventilation services in places outside a hospital. Calea is Linde's third acquisition in 2012 in the healthcare business. In April, Linde acquired Air Products' Continental European homecare business, and in August it concluded its purchase of the US homecare company Lincare Inc.

Linde's pro-forma annual revenue in the healthcare product area is now around €3 billion, which makes it the largest supplier of medical gases and related services in the world.
