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 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 demand to save energy and cost. The cycling dryer is ideal for partial airflow demand, where compressed-air demand on the network goes up and down over time.

These all-new dryers deliver consistent high performance alongside 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.

Key Improvements vs Previous Models

• 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, easy maintenance.

Innovative Control Panel

• 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 iConn: remote monitoring, preventive maintenance, free cloud portal.

New 3-Layer Heat Exchangers

Designed and developed in our laboratories to deliver the highest 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

Provide 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 drain logic is managed by the main control panel.
