Refrigerant Compressed Air Dryer
Non Cycling Refrigeration Dryers
Energy Efficient CD-Series
First-class air treatment efficiency
The CD-Series refrigerant dryers are carefully selected depending on working conditions with continuous dew point monitoring enabling reliable operation with the lowest possible pressure losses and running costs.
This range offers a wide range of kW sizes and caters for a larger range of airflows than the cycling dryer range.
The non-cycling dryer is ideal for constant airflow demand, where the compressed air demand on the network stays the same over time.
These all new dryers deliver consistent high performance along side optimised energy efficiency, increased environmental credentials and a lower total cost of ownership.
They are a step ahead of both the EU and the competition – supporting sustainability with low GWP refrigerants for ISO Class 4 (+3°C PDP) markets.
Compared to previous models, this next-generation of dryers deliver:
Reduced power consumption of up to 10%
Up to 27% lower pressure drop
Significant footprint reduction of up to 40%
CompAir CD-series refrigerant dryers deliver acomprehensive, cost-effective solution to multipleapplications across a wide range of sectors includingautomotive, manufacturing, petrochemical, oil and gas, dry cleaning and light processing to name a few.
Optimum efficiency by Design
These dryers have been designed to provideclean, dry air which means less corrosion in the airdistribution system, less damage to air-powered tools, and reduced potential for contamination in the productionprocess. The design features of CompAir CD dryers notonly ensure constant dew point at all load levels, butalso deliver continuous dry air performance that meets the most challenging ISO8573 1 and ISO7183 industry standards.
Features
Air Cooled Condensation (as standard)
Victaulic Connections (optional)
Reliable Design
Reduced Footprint (30% smaller than previous model)
Innovative Control Panel
Anti-freeze mode
Alarm display
Remote ON/OFF (optional)
Alarm history
Condensate drain management
New Heat Exchangers
Innovative No-loss Drain
A refrigerated air dryer removes moisture from compressed air by cooling it, condensing the water vapor, and draining it out. This protects downstream equipment and improves air quality.
⚙️ Non-Cycling Refrigeration Dryers
A non-cycling dryer runs its refrigeration compressor continuously, regardless of air demand.
✔️ Key Features:
Constant operation (compressor always ON)
Stable dew point (typically around +3°C)
Simple design → fewer controls, lower upfront cost
Good for steady air demand applications
❌ Limitations:
Higher energy consumption during low load
Less efficient if your air demand fluctuates
⚡ Energy Efficient “CD-Series” (Typical Characteristics)
Manufacturers often label improved non-cycling dryers as “energy efficient” by optimizing components.
Common enhancements:
High-efficiency heat exchangers
Low pressure drop design (saves compressor energy)
Eco-friendly refrigerants (like R134a or R410a)
Electronic drain valves to reduce air loss
Better insulation to reduce thermal loss
