Designed for cooling air flow from 25 to 2000 liter / second

Air dryers are self-contained units designed for cooling air flow from 25 to 2000 liter / second in for instance the chemical, textile and plastics industry. Air dryers are highly efficient in use, removing moisture and contaminants from compressed air by chilling the air and condensing the moisture. The water droplets are then separated from the air stream and discharged from the dryer.
Danfoss offers a complete range of products, including compressors, controls, electronic controllers, sensors and heat exchangers to build refrigerated air dryers.

Features and benefits

Thermostatic and electronic expansion valves for efficient regulation

Filter driers, sight glass, shutoff valves for reliable system protection

Solenoid valves for effective control and removal of moisture from air

Sensors for accurate temperature measurement & moisture-free air

Evaporating pressure regulator for constant suction pressure and evaporator temperature
