Overview
Cold-regenerated, oil-free adsorption dryer DRYBERG® AD820 CT designed for continuous removal of water vapor from compressed air to lower the pressure dew point.

Highlights

• Cold-regenerated, oil-free adsorption drying process
• Durable construction for industrial environments
• Reduced maintenance through design adapted to dust and humidity
• User-friendly controls and easy access to service components

Detailed description
The DRYBERG® AD820 CT uses two alternating adsorbent towers (twin-tower system): one tower adsorbs moisture at pressure while the other regenerates. A small portion of dried compressed air is used for regeneration, ensuring effective drying performance and continuous operation without pressure drop at the outlet.
