- Desiccant dryer with heatless regenerationThe high-pressure desiccant dryer works on the PSA (Pressure Swing Adsorption) principle with heatless regeneration for reliable drying of compressed air or nitrogen.
- Pre-filter and after-filterThe system is equipped as standard with a pre-filter for removing particles and condensate and with an after-filter that retains any desiccant particles.
- Manual condensate drainThe standard version includes a manually operated condensate drain for simple removal of separated condensate from the system.
- LED status displayThe visual display of operation gives a clear overview of states such as adsorption, regeneration, pressurisation, service and alarm.
- Pneumatically controlled seat valvesThe robust valve design provides high operating reliability, low pressure loss and low maintenance costs.
- Prepared for high-pressure applicationsPN 25 and PN 40 versions are available for systems with an operating pressure from 17 to 40 bar, depending on the selected model.

Benefits
Exceptional Drying Down to -40 °C
Adsorption technology (PSA) provides a stable pressure dew point down to -40 °C, which allows safe use even in the most demanding industrial applications.
High Operating Reliability
Pneumatically controlled valves, a robust design and continuous process monitoring provide safe and stable operation with minimal downtime.
Low Operating Costs
A large filtration area and an optimised design reduce pressure drops, which means lower energy consumption and lower operating costs.
Clear Operating Overview
The LED display gives an immediate overview of the system status (adsorption, regeneration, alarm), which simplifies operation and servicing.
Energy-Efficient Regeneration
Heatless regeneration using a portion of the dried air enables reliable operation without additional energy sources.
Adaptable to the Application
Options such as dew point control, an electronic condensate drain and a control air supply are available, which allows the system to be optimally adapted.
Easy System Integration
The dryer can be connected to a compressor and to central systems, which optimises regeneration air consumption and makes the entire system more efficient.
