Salle blanche HVAC et équipement de manutention de l'air
Unité de traitement de l'air de la salle sèche
An integrated desiccant air handler that combines deep moisture removal, regeneration, cooling and recirculation for ultra-dry production rooms.
- Desiccant Rotor Drying
- Low Dew-Point Supply
- Separated Regeneration Air
- High Recirculation Efficiency
Introduction de produit
The dry room air handling unit removes water vapor beyond the practical range of cooling coils by passing process air through a continuously regenerated desiccant rotor. A pre-cooling stage reduces incoming moisture load, the rotor performs deep drying, and post-cooling controls supply temperature. A separate heated regeneration airstream removes captured moisture from the rotor and discharges it outdoors. Recirculating most of the dry-room air limits the outdoor moisture load, while sealed casing and low-leakage dampers protect the achieved dew point.
Key Features
Separated process and regeneration air paths prevent wet regeneration exhaust from mixing with dry supply air.
Pre-cooling and sensible post-cooling reduce rotor load and set the final supply temperature.
High dry-air recirculation minimizes the quantity of humid outdoor air that requires deep treatment.
Préoccupations du client produit
Ultra-low humidity is easily lost through casing leakage, door infiltration, wet regeneration carryover and moisture released by process materials.
A chilled-water coil cannot reach the required dry-room dew point.The desiccant rotor adsorbs remaining vapor after the air is precooled.
Regeneration exhaust leaks into the dry process airstream.Sealed rotor sectors, pressure control and purge arrangements limit cross-stream carryover.
Opening personnel or material doors causes slow humidity recovery.Sufficient recirculation airflow and controlled dry-air make-up remove the infiltration moisture load.
Reactivation heat dominates system energy use.Purge optimization, heat recovery and the appropriate steam, gas, electric or heat-pump source reduce regeneration demand.
