Adsorption dryers with flowrates from 6.7 to 141.7 m3/min

Delivering reliability, performance, and customer value

Gardner Denver GDX-Series desiccant dryers deliver a comprehensive, cost-effective solution to multiple applications across a wide range of sectors and is engineered for easy access, energy efficiency, and a long service life.

Gardner Denver GDX-Series features are your benefits

• Maximum reliability - Robust valves ensure consistent and reliable dryer operation.
• Robust switching and purging valves - Switching valves are normally open, while purge valves are normally closed to allow air flow through the dryer in case of power loss. Valves are designed for a high working cycle and long life. Purge valves are also provided with position indicators to facilitate performance check.
• High performance valves - Switching and purging valves provide quick response and are designed for high cycle, long life. Butterfly valves have stainless steel disc for high resistance. Purge valves are provided with position indicators for performance monitoring.
• Low life costs - Intelligent performance check protects uptime whilst lowering total cost of ownership.
• External solenoid valves - Easily accessible control air solenoid valves for easy service. New valves also feature manual override to facilitate performance check. Plus, a new push to test feature allows the controller program to energise individual solenoid valves to aid in diagnosing valve-related issues.
• Low profile design - Our low profile design provides easy access to key maintenance points at operator level for faster servicing and less downtime. The lower silhouette also allows upright shipment (whilst minimising shopping costs) and facilitates simpler installation. Installation is even possible in low overhead clearance areas due to the reduced height versus our competition.
• Side-mount inlet and outlet manifolds - Side mounted upper and lower manifolds provide unobstructed access to all valves for unmatched serviceability compared to competitive designs.

Intelligent performance monitoring protects uptime whilst lowering total cost of ownership.

Quick Return of Investment downstream processes. (ROI) with optional Energy Management System (EMS)
EMS can significantly reduce operating cost by limiting purge air consumption in proportion to moisture loading on dryer. It uses ceramic sensor technology that provides the fastest documented response to dew point changes. Through energy management, your ROI can be less than one year! Available in all models and configurations.

GDF-Series filters
Prefilter and afterfilter Included in standard scope of supply

Prefilter – High efficiency prefilter also does particle removal down to 0.01 micron. Maximum remaining oil aerosol content of 0.01 mg/m3 at 21°C, protecting and extending the life of the desiccant bed.

Afterfilter – Heavy duty afterfilter provides Class 2 particulate air downstream, ensuring high quality downstream air for the customer.
Includes differential pressure gauge for easy monitoring and guarantees certified performance.
