(Archived) Praxair China Wins Contract for Reactor Cooling
SHANGHAI, China, July 7, 2008 — 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™) 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 –30C 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™ 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™ 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™ heat exchanger is used for precision cooling of production freeze-dryers and chemical reactors.
