Tunnel Freezer Praxair Inc. announced the introduction of its newest tunnel freezing system, the Praxair ColdFront Cryo-Saver Tunnel Freezer. The system employs advanced technologies developed by Praxair that expand the ability of processors to freeze more economically in the same footprint of a traditional cryogenic tunnel system. The Cryo-Saver Tunnel Freezer’s entrance and exit are uniquely positioned to decrease the infiltration of room air into the freezer, which can result in up to 15% savings in customer operating costs depending upon the production parameters. The freezer enclosure is also designed to meet new USDA sanitation standards and make clean-up quick and thorough. Praxair Inc.: (800) 772-9247 or visit www.praxairfood.com
