Air Products’ new Freshline Z Tunnel Freezer combines cryogenic refrigeration, indirect heat transfer and impingement technology. The unit does not require an exhaust fan like conventional cryogenic freezing tunnels. It has an indirect freezing system that uses liquid nitrogen to cool circulating air.

The elimination of the exhaust fan also results in a system that’s easy to control and operate. The only parameters the operator controls are temperature and belt speed. Temperatures and heat coefficients are stable which enable freezing and product quality for seafood, meat poultry, frozen meals and other foods.
