Freezing Tunnel Exhaust System

The Quickdraft Venturi exhauster is an excellent solution for a variety of exhaust processing applications in the food industry. There are no moving parts in contact with the exhausted cryogenic gas. Food particles fall out of the airstream inside the velocity reduction chamber improving pest control, reducing maintenance costs by reducing the number of roof cleanings, and extending the service life of the roof.
