Systèmes utilitaires Cleanroom
Séchoir d'air réfrigéré par
A standalone air-cooled refrigerated dryer that cools compressed air, separates condensed water and reheats the dry outlet stream for general cleanroom utility service.
- 167 L/s reference inlet flow
- +3°C pressure dew point class
- Electronic automatic condensate drain
Introduction de produit
The Refrigerated Air Dryer is a self-contained compressed-air treatment cabinet installed downstream of a compressor and wet receiver. Incoming warm, moisture-laden air is first precooled by the outgoing dry stream, then cooled further in a refrigerant-to-air heat exchanger so water vapor condenses. An internal separator removes the liquid and an electronic drain discharges it without making the dryer a storage vessel. The outgoing air is reheated in the air-to-air section to reduce external pipe sweating. The selected medium-capacity unit has one service door, one large condenser-air grille, two top compressed-air connections, a compact dew-point controller and four fixed feet. It contains a hermetic refrigerant compressor and heat exchangers, but no air-compression element, desiccant towers, filter cartridges, air receiver or comfort-air-conditioning ductwork.
Key Features
The refrigeration circuit supports a stable positive pressure dew point without consuming purge air
An internal condensate separator removes liquid formed at the coldest point of the air path
An electronic level-controlled drain releases collected condensate automatically
A front digital controller provides local dew-point, operating-status and alarm indication
A large lower condenser grille gives the air-cooled refrigeration circuit a direct ventilation path
Two top-mounted air connections keep wet-air inlet and dry-air outlet piping clear of the service door
One hinged front door provides access to the heat exchanger, separator, refrigerant compressor and drain
Préoccupations du client produit
Compressed air cools as it moves through plant piping, so water vapor can condense after the compressor unless moisture is removed at a controlled pressure dew point.
Condensate in distribution piping can corrode components and disrupt pneumatic equipmentCool the full air stream to the selected pressure dew point, separate the resulting liquid and discharge it before the air enters the distribution header.
A dryer selected only by nominal compressor output may be undersized at high inlet or ambient temperatureApply manufacturer correction factors for actual inlet flow, pressure, inlet temperature and ventilation conditions before selecting the dryer size.
Blocked condenser airflow can raise refrigerant pressure and destabilize drying performanceKeep the front condenser grille and service clearance unobstructed and include condenser cleaning in routine maintenance.
A failed or obstructed condensate drain can carry separated water back into the outlet airUse the accessible electronic drain, route its discharge visibly and verify drain operation during scheduled inspections.
Users may expect a refrigerated dryer alone to provide sterile or ultra-low-dew-point airTreat the dryer as the moisture-removal stage and select downstream particulate, oil-removal or sterile filtration separately for the required air quality.

Paramètres techniques
The selected catalogue-scale identity is a standalone air-cooled, non-cycling refrigerated dryer sized around 167 L/s at a +3°C pressure dew point, 7 bar reference pressure, 35°C inlet air and 25°C ambient conditions. Its representative cabinet envelope is approximately 898 mm wide by 735 mm deep by 1002 mm high, with two 2-inch female compressed-air connections and a 13 bar maximum working-pressure class. Actual flow capacity, pressure drop, electrical supply, refrigerant, inlet-temperature allowance and drain arrangement depend on the selected model and site conditions.
