The DIF dryer series produces an air flow with low humidity content with a dew point temperature in output equal to -15°C, preventing the formation of condensation on the surfaces of the moulds.

The dehumidifying system is made up of a high efficiency desiccant rotor that absorbs the molecules of water present in the air. A constant flow of warm dry air goes through a portion of the rotor extracting the humidity from the rotor and expelling it into the atmosphere.
