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.
