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
مقدمة المنتج
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.
الخصائص الرئيسية
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.
مخاوف المنتج للعملاء
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.
