Modular Desiccant Dryers with flowrates from 0.08 to 4.00 m3/min
Gardner Denver offers a wide range of modular desiccant dryers, each designed to meet the specific needs of users. At the heart of every compressed air system is a desiccant. Its purpose is to remove water vapour and prevent condensation and corrosion. The dryers guarantee the highest air quality - clean, oil-free and dry, in accordance with all international quality standards.
The GDX1M - GDX50M models are robustly constructed and are distinguished by their versatility, making them suitable for use in all industries and applications.
The Gardner Denver GDX-series dehumidifiers use the heatless PSA method to regenerate the adsorbent material. The design does not heat up and minimises maintenance costs.
Energy efficient desiccant dryers
Clean, dry air improves production efficiency and reduces maintenance costs and downtime. Desiccant dryers provide the highest levels of dry compressed air.
Features are your benefits:
- High Air Quality - delivers ISO Class 2 or Class 1 pressure dew point air for critical applications; high efficiency pre and post-filters provide constant high air quality, protecting downstream air from contamination.
- Superior Reliability - proven electronic control performance indicators, extruded aluminium with anodisation and epoxy painting, and NEMA 3/IP54 Protection (also suitable for outdoor installation) make desiccant dryers durable and high-strength.
- Total Cost of Investment - reduced cost of ownership with point of use design to treat only the required air, conservative pressure drop 0.2 Barg, and purge reduction on compressed air demand (on/off-load).
- Ease of Use - user-friendly electronic interface with alarm indicators available for models 40 and above.
- Serviceability - modular dryers feature an optimised design for simplified maintenance and preventative maintenance alerts (models 40 and above).
- Compact & Flexible Solution - space-saving design for optimised installation with air inlet and outlet in the back of unit and connection piping can come from right or left. Model up to 0.42 m3/min can be wall-mounted or installed horizontally.
- Performance Improvement - extended rated pressure range from 4 to 14 Barg and increased airflow range coverage up to 300 m3/h. Guaranteed class 2 (-40°C) and optionally class 1 (-70°C) pressure dew point.
- Longer Cycle Life - modular dryers have a longer cycle time, 10 minutes, than most competitors (4 to 8 minutes maximum).
GDX-Series modular compressed air dryers - a dedicated solution for every application
By combining the proven benefits of desiccant drying with modern design, Gardner Denver provides an extremely compact and reliable system to dry and clean compressed air efficiently.
Robust and reliable industry-proven design.
Suitable for all industries and applications - some desiccant dryer regeneration methods prevent their use in certain industries/applications.
Lower capital investment and reduced complexity compared to other dryer regeneration methods.
Lower maintenance costs in comparison to other dryer regeneration methods.
No heat, heaters, or heat-related issues.
