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.
This is describing a refrigerated compressed air dryer system, specifically a cycling refrigeration dryer (CDF-ES series) designed for energy-efficient air treatment.
Here’s a clear, detailed breakdown:
What a refrigerated air dryer does
When air is compressed, it contains:
Water vapor (humidity)
Sometimes small oil aerosols and dust (depending on compressor type)
A refrigerated air dryer removes moisture by:
Cooling compressed air close to freezing temperature
Turning water vapor into liquid water
Separating and draining the water out
The result is dry compressed air, which prevents:
Rust in pipes and equipment
Damage to pneumatic tools
Product contamination in sensitive industries
What “Cycling Refrigeration Dryer” means
A cycling dryer (like the CDF-ES series) does not run constantly.
Instead:
It turns the refrigeration system on and off automatically
Based on how much cooling is actually needed
How it works:
If air demand is low → compressor cycles OFF (saves energy)
If humidity load increases → system cycles ON again
Why this is energy efficient (key benefit)
Traditional dryers:
Run refrigeration continuously
Waste electricity even when demand is low
Cycling dryers:
Adjust operation based on load
Reduce compressor run-time
Lower electricity consumption significantly
This is why it’s called:
👉 “Energy Saving CDF-ES Series”
Main advantages of CDF-ES type dryers
1. Energy savings
Reduced power usage during partial load conditions
Ideal for factories with variable air demand
2. Stable dew point control
Maintains consistent air dryness
Protects sensitive equipment
3. Lower operating cost
Less electricity consumption over time
Reduced wear on refrigeration components
4. Reliable moisture removal
Suitable for general industrial compressed air systems
Where these dryers are used
Refrigerated cycling dryers are commonly used in:
Manufacturing plants
Automotive workshops
Packaging industries
Textile and printing units
General industrial compressed air systems
Important concept: “Air treatment”
The phrase “high efficiency air treatment” means this system is part of a full compressed air line, which may include:
Air compressor (creates compressed air)
Aftercooler (initial cooling)
Water separator (removes bulk moisture)
Refrigerated dryer (final drying)
Filters (remove oil/dust particles)
So the dryer is one part of a complete air quality system.
Simple explanation
Think of it like:
Compressor = produces air
Dryer = “air dehumidifier”
