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.

It looks like you’re referring to a specific type of industrial equipment—let me break it down clearly so you understand what it is and how it works.
🔧 Refrigerant Compressed Air Dryer (Overview)
A refrigerant compressed air dryer is used in compressed air systems to remove moisture from air. Moisture can damage tools, pipelines, and machinery, so drying the air is essential.
How it works:
Warm, moist compressed air enters the dryer
It is cooled using a refrigeration system
Water vapor condenses into liquid
The liquid is separated and drained out
Dry air exits the system
🔄 Cycling Refrigeration Dryers
A cycling dryer is a more energy-efficient version of a standard (non-cycling) refrigerated dryer.
Key idea:
Instead of running the refrigeration compressor continuously, it cycles ON and OFF based on demand.
Benefits:
⚡ Energy savings (major advantage)
🔇 Reduced wear and noise
🌡 Maintains stable dew point with thermal storage
How it differs:
Non-cycling dryer → runs all the time
Cycling dryer → runs only when needed
