Cooling Tunnels / Tempering Tunnels

The autotherm ATT temperature control tunnels work with a specially positioned air duct that generates the desired air temperature. The air is swirled in this duct directly above the conveyor belt to achieve the most effective cooling or heating possible.

This innovative recirculating air system not only makes the temperature control tunnels energy-efficient, but is also largely independent of the ambient temperature.
