Air Products to Design and Build NASA’s New $16.8 Million Liquid Nitrogen Plant

2008 Start-up for Project Continuing a Half-Century of Working Together

LEHIGH VALLEY, Pa. (October 4, 2007) – Air Products (NYSE: APD) today joined NASA at Langley Research Center in Hampton, Va. in a groundbreaking ceremony for a new $16.8 million liquid nitrogen plant for NASA’s National Transonic Facility (NTF). The new plant, designed and supplied by Air Products, is scheduled for a 2008 start-up. It will be owned by NASA and operated by NASA’s on-site support contractor. Air Products won the competitive procurement for a turn-key, fixed price contract, based on a “best value to the government” evaluation completed in September 2006.

NASA’s National Transonic Facility contains several high-tech operations, including the largest cryogenic wind tunnel in the world. NTF uses liquid nitrogen to produce a high-quality, high-altitude test environment for aircraft development and refinement. The new dedicated plant will provide NASA with a secure, long-term supply of liquid nitrogen, substantially reducing the cost of research and testing at the facility. NTF performs research and development testing for government and non-government applications, including aerospace and commercial customers.

“We have actively participated in the competitive process since NASA’s initial market surveys for product supply. This liquid nitrogen plant groundbreaking represents a significant milestone for everyone. We are expecting a successful project completion, and we are targeting to do so ahead of the required contract completion date. The combined efforts of our dedicated project teams at both Air Products and NASA will make this a safe and successful project,” said Steve Meholic, business manager, Air Separation Equipment at Air Products.
