The Air Products Freshline IQ cryogenic tunnel freezer has a heat-transfer capability that enables vaporized liquid nitrogen to be dispersed throughout the tunnel. It includes large openings for easy access and sloped surfaces to eliminate standing water. An optional remote monitoring system enables the tracking of real-time variables and remote troubleshooting. Based on 10-ft. modular units that can be integrated into an existing production line, the freezer can be expanded on-site.
