Deep-freezing and blast-chilling tunnels for trolleys

The deep freezing chambers or tunnels are designed for industrial units requiring high performance devices that can deep-freeze (shock freeze) (-35°C, -18°C core temperature) very large volumes in a minimum amount of time. Flexible and power adaptable, they are designed to hold grids and gastronorm trolleys. They can freeze all kinds of products according to your needs:  pastry, viennoiserie, fruits, vegetables, meats, prepared dishes, plants ... 

Deep-freezing tunnel for all size of trolleys / racks
Removing of a frozen vienneses bread trolley in less than 10 minutes
Cold generation by vertical evaporator
Easy access to the evaporator for maintenance and cleaning
Stainless steel lateral inside protection
Large handle with locking possibility
From -18°C to -35°C
