Praxair China Wins Contract for Reactor Cooling

SHANGHAI, China--(Business Wire)--
Praxair China, a subsidiary of Praxair, Inc. (NYSE: PX), has
signed a contract to supply liquid nitrogen and a state-of-the-art
nitrogen cooling system (NCOOL(TM)) to the Jiangsu Defeng
Pharmaceutical & Chemical Co., Ltd. (Defeng).

Defeng produces active pharmaceutical ingredients and will
introduce a new product which requires rapid cooling to below
-30-degree C in a large volume reactor. After a thorough market
survey, Defeng selected Praxair China as its product and technology
supplier. The decision was based on the quality of the liquid
nitrogen, reliability and the new technology offered by Praxair.

"This new application of the NCOOL(TM) technology opens up another
segment of the fast growing cryogenic refrigeration market in the
pharmaceutical industry," said David Chow, president of Praxair China.

The NCOOL(TM) indirect cooling system features the highly
efficient Praxair cryogenic heat exchanger. Because this cooling
system uses the heat exchange from nitrogen rather than mechanical
refrigeration, it has minimal moving parts and does not rely on
halogenated coolants (CFCs or other ozone-depleting substances). The
NCOOL(TM) heat exchanger is used for precision cooling of production
freeze-dryers and chemical reactors.
