Praxair's ( PX) Canadian unit signed a dry-ice supply pact with Air Canada. Danbury, Conn.-based Praxair didn't disclose terms but said the exclusive long-term pact covers the annual use of more than 2 million pounds of individual dry-ice packets to transport food and beverages between flight-kitchen facilities and aircraft. Praxair Distribution will supply airline dry-ice slices for food preparation facilities at seven international airports in Canada. An initial pilot project to test Praxair's product and supply system was successfully completed in Vancouver, British Columbia, in January 2005. Since then, the servicing of the remainder of the supply chain to Air Canada facilities at airports in Calgary and Edmonton, Alberta; Winnipeg, Manitoba; Toronto and Ottawa, Ontario; Montreal, Quebec, and Halifax, Nova Scotia, has begun. "Praxair is the only company in Canada with dry ice capability and a reliable distribution network available from coast to coast," said Janet Coffman, vice president of business development for Praxair Distribution. "This contract with Air Canada solidifies our national sales and distribution programs, and provides a very exciting opportunity to grow our business." Shares of Praxair fell 40 cents to $46.16.
