We supply fully automated systems for shock freezing, temporary storage and/or tempering of food in cartons or boxes.

AAT BoxFreezers are among the most advanced freezing plants on the market. The products are loaded into the BoxFreezer automatically through a lock, then shock frozen and automatically unloaded when they have reached the target temperature. The BoxFreezer works optimally with throughputs from 3 to 30 tonnes per hour.

The principle is simple, but the plant can be used in many different ways: single-zone shock freezing, our multitemp freezing mode or with complex adaptation to the industry 4.0 standard.
