Abstract (en)

[origin: EP0583692A1] A control system for a tunnel freezer (1) comprises an oxygen sensor (310) mounted in an exhaust duct (9) and arranged to control the speed of a fan (8). The temperature in the tunnel (4) is determined by controlling the flow of liquid nitrogen through inlet pipe (5) via a control valve (308) which is controlled in response to the signal from a temperature sensor (301). <IMAGE>
