C: central airduct for outlet damp air • When air from the drum is more damp than outside, this will be dispatched.
B: central airduct for inlet outside air • Starting with heated outside air a large quantity of water is drained. • When required, dehumidified air will be added to a drum-unit to continue optimal drying.
A: Central inlet for dehumidified air • Dehumidified air will enter a drum dryer when drier air is required. • When air out of the drum is drier than outside, this will be recirculated. • Drying continues with dehydrated air.
Slide inside for extracting outside or recycled air. Optional with dehumidified air.
Outside air is warmed up to the desired temperature to absorb moisture. Outside air and dehumidified air can be mixed to decrease AH and increase drying capacity.
When air out of the drum is more damp than outside, it will be dispatched outside (middle).
When air from the drum is drier than outside, this is recirculated and mixed with dehumidified air (left).
Final moisture from the product will be drained by dehumidified air.
