Compressed Air Dryers
Refrigerant Compressed Air Dryer
Cycling Refrigeration Dryers
Energy Saving CDF-ES Series
High efficiency air treatment
The cycling dryer is designed to deliver the lowest cost solution by focusing on all of the cost contributors. In a typical compressed air dryer, the refrigerant compressor runs continuously regardless of demand. With a cycling dryer, circulating glycol cools the compressed air allowing the refrigerant compressor to turn-off during low demands, to save energy and cost
The cycling dryer is ideal for partial airflow demand, where the compressed air demand on the network goes up and down 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%
Reliable and Simplistic Design
Microprocessor control and no-loss Smart Drain increase reliability, while dryer self-regulation, plug-and-play installation and readily available parts make for simple and easy maintenance.
Innovative Control Panel
With all the main functions you would expect to control and monitor the unit:
Anti freeze mode – shuts dryer off to avoid icing
Alarm display: Dew Point, high/low temperature, High ambient temperature
Remote ON/OFF optional up to CD160F-ES, standard from CD216F-ES
Alarm history
Condensate drain management
Ready for Industrial IOT with adoption of iConn, remote monitoring, preventive maintenance, free cloud portal
New 3-layer Heat Exchangers
Designed and developed in our laboratories to deliver the highest levels of performance with the lowest pressure drop. The adoption of the new CompAir heat exchanger has enabled the removal of the inlet and outlet headers.
Glycol Pumps
Provides a constant circulation of glycol with the compressor on or off.
Innovative No-loss Smart Drain
Fitted as standard, a sensor is installed directly in the moisture separator and control logic is managed by the main Control Panel.

🔹 Compressed Air Dryers (Overview)
A compressed air dryer is used to remove moisture from compressed air to prevent:
Corrosion in pipelines
Damage to pneumatic tools
Product contamination (especially in food/pharma)
Common Types:
Refrigerated dryers
Desiccant (adsorption) dryers
Membrane dryers
🔹 Refrigerant Compressed Air Dryer
A refrigerant dryer is the most widely used type.
How it works:
Air is cooled using a refrigeration system
Moisture condenses into water
Water is separated and drained out
Key features:
Typical dew point: +3°C to +10°C
Low operating cost
Simple and reliable
Best for:
General industrial use
Workshops, manufacturing plants
Pros:
Energy efficient (compared to desiccant in many cases)
Low maintenance
Cons:
Not suitable for extremely dry air needs
Performance drops in very hot environments
🔹 Cycling Refrigeration Dryers
A cycling dryer is an advanced type of refrigerant dryer.
How it differs:
Instead of running continuously, the refrigeration system cycles ON/OFF based on demand
Uses a thermal mass (like glycol or aluminum block) to store cooling
Key features:
Saves energy during low load conditions
More stable dew point under varying loads
Best for:
Facilities with fluctuating air demand
Plants looking to reduce electricity costs
Pros:
Up to 30–50% energy savings vs non-cycling dryers
Longer compressor life (less continuous running)
Cons:
Higher initial cost
Slightly more complex design
🔄 Non-Cycling vs Cycling (Quick Comparison)
Feature Non-Cycling Dryer Cycling Dryer
Operation Runs continuously Turns ON/OFF based on demand
Energy use Constant Variable (lower overall)
Cost Lower upfront Higher upfront
Efficiency Lower at partial load High at partial load
🧠 Simple Analogy
Non-cycling dryer = Fan running all day
Cycling dryer = AC that turns on/off to maintain temperature
