Ultra-faible point de rosée déshumidificateur
A high-performance desiccant air-treatment unit engineered for dry rooms that require stable supply-air dew points below conventional comfort or process ranges.
- Ultra-Low Supply Dew Point
- Purge-Sector Heat Recovery
- Multi-Stage Air Conditioning
- Precision Dew-Point Feedback
Introduction de produit
The ultra-low dew point dehumidifier integrates deep precooling, a high-performance desiccant wheel, reactivation heating, purge heat recovery and aftercooling in one modular casing. The purge sector captures heat and moisture profiles that would otherwise limit the wheel at very low outlet humidity. A dedicated dew-point transmitter and modulating controls stabilize dry-air delivery for battery materials and other hygroscopic processes with large recirculation rates.
Key Features
A purge sector recovers useful heat within the wheel and reduces the reactivation energy required per kilogram of water removed.
Precooling lowers the incoming moisture load before the rotor, while aftercooling delivers air at the required room supply temperature.
PLC sequencing coordinates fans, chilled-water valves, reactivation output, rotor speed and dew-point alarms as one system.
Préoccupations du client produit
Ultra-dry manufacturing combines a very small moisture target with large personnel, infiltration and process loads that change throughout the shift.
A standard rotor stalls above the dew point required by moisture-reactive battery chemistry.The low-dew-point rotor, deep precooling and purge geometry preserve adsorption driving force at very low outlet humidity.
Reactivation heat becomes the dominant utility cost in a continuously occupied dry room.Purge heat recovery and modulating reactivation reduce heater demand during both design and part-load operation.
Door openings create sudden moisture spikes that threaten product exposure limits.Fast dew-point feedback increases dry-air capacity while the large recirculation flow restores the room moisture balance.
Uncoordinated cooling and drying controls cause unstable room temperature.One PLC stages precooling, adsorption and aftercooling to meet dew-point and dry-bulb targets independently.
