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.

Here’s the basic working principle:
Compressed Air Enters the Dryer
Hot, moist compressed air passes into the dryer.
Cooling and Condensation
A refrigeration system cools the air, causing water vapor to condense into liquid droplets which are then separated and drained.
Energy Storage / Thermal Mass
The system cools a thermal mass (such as glycol or metal blocks) that acts as a cold reservoir. This cooled mass continues to help dry air even when the refrigeration compressor is off.
Cycling Operation
When the cold storage and air demand allow, the refrigeration compressor shuts off to save energy. It restarts only when needed to maintain temperature and dew point.
This on/off action — “cycling” the refrigeration compressor — is what gives cycling dryers their name.
