AC Cycling Refrigeration Dryers

Reliable refrigeration drying with the possibility of activating energy-saving features to save your money.

The AC Series Cycling Dryers are equipped with Pneumatech’s proprietary energy-saving algorithm, which adapts the energy consumption to the real load, lowering your operational costs.


Compressed Air Refrigerant Dryer for Maximum Efficiency 

Where less cooling is required, the refrigerant compressor stops, and power consumption is significantly reduced, with savings up to 50%. AC250-600 dryers are also equipped with a flow switch that detects whether there is flow going through the dryer and shuts down the refrigerant compressor when there is no flow. To make these energy-saving functionalities work, the AC range makes use of advanced controllers, which communicate through voltage-free contacts or industrial protocols.

Pneumatech’s AC range offers premium refrigeration drying technology at the lowest operational costs. All AC dryers are equipped with our proprietary energy-saving algorithm, which adapts the energy consumption to the real load by continuously monitoring the ambient temperature and the pressure dewpoint.

In this way, the risk of downstream corrosion is reduced to zero at all times. When there is less cooling needed, the refrigerant compressor stops, and power consumption is significantly reduced, with savings up to 50%.

Premium energy efficiency is also guaranteed thanks to low pressure drops over the heat exchangers, zero-loss drains, and our winning combination: rotary compressors and R410A refrigerant on AC125-200. This combination is up to 30% more energy efficient, requires 19% less refrigerant gas, and is 100% compliant with European regulation EU No 517/2014

The Benefits of AC Refrigeration Dryers


Premium Energy Efficiency

The patented energy-savings algorithm starts and stops the dryer to save energy while keeping the relative humidity of the compressed air below 50% to prevent the formation of liquid water.

PurelogicTM Controller

An easy-to-use controller with an energy-saving algorithm, dewpoint or relative humidity display, freeze protection, high humidity alarm, and ambient temperature offset.

Zero-Loss Drain

Pneumatech’s zero-loss drains save you money by preventing the loss of valuable compressed air associated with other types of drains.

Superior Reliability

  • Guaranteed drying performance in wide range of temperature conditions
  • Rotary refrigerant compressors: limited mechanical load and low vibrations (for AC125-2100)
  • Refrigeration cycle optimized in all conditions thanks to automatic expansion valve & electronic hot gas bypass valve (for AC650-2100)

Easy Installation & Maintenance at Low Cost

  • Pipe Connections on Top
  • Long Service Intervals
  • Easy to Access Key Components


Remote alarms keep you informed of service intervals and potential problems while the remote start and stop feature opens a whole new list of possibilities to control the dryer.
