(Archived) Praxair Introduces New Cylinder Monitoring Service

DANBURY, Conn., November 21, 2006 — Praxair Distribution Inc., a wholly-owned subsidiary of Praxair, Inc. (NYSE: PX), announced today the commercial introduction of its new wireless pressure monitoring service for remote management of cylinder gases. Praxair's Remote Cylinder Monitoring Service consists of wireless communication pressure gauges and Praxair's proprietary prediction software for providing continual pressure readings of gas products at a customer's site. Subscribers to this service will be able to view their individual cylinder pressures and actual product usage from any PC with an internet connection through a web-based application.

"We have been working very closely with our customers to optimize this service," said Lisa Taylor, vice president of gases sales. "The technological advances made over the past several years in wireless communication and web-based software applications along with the development of our custom predictive software have enabled Praxair to provide this unique service. The potential future applications of combining these technologies will be significant for customers with multiple cylinder use points," she continued.

"The Chemistry Department at Niagara University has seen the usefulness in the system," stated Scott Nash, technical & laboratory supervisor, Niagara University Chemistry Department. "Praxair's remote cylinder monitoring service has completely surpassed my expectations. We were recording the tank readings twice a week in a logbook to determine gas use trends. Now with this system we are able to monitor our gases without ever leaving our offices."

Praxair is initially offering two levels of service – Silver and Gold. Features include 24/7 monitoring, pre-set or customizable pressure threshold settings, web screen alerts and e-mail notifications for low level product and cylinder change out conditions to help customers avoid costly run-outs. Gold level customers will have the additional option of electronic ordering of replacement cylinders through Praxair's on-line ordering site.
