DANBURY, Conn., May 16, 2008 — Praxair, Inc. (NYSE: PX) has signed joint marketing agreements with Atmosphere Engineering Company and with Super Systems, Inc. in order to combine the core competencies of each company into a superior comprehensive solution for heat-treat customers.

Under these agreements, heat-treat customers will have access to a simplified market channel which integrates Praxair’s gases, applications technologies and supply systems with process controllers and data acquisition software from Super Systems and precise furnace control panel systems from Atmosphere Engineering. The combined capabilities of Praxair, Atmosphere Engineering and Super Systems cover a broad spectrum of batch and continuous heat-treating processes such as carburizing, carbonitriding, neutral hardening, annealing, gas quenching and heat treatment under vacuum.
