Refrigerated Dryers

<< Back to Pneumatech page

Refrigerated air dryers use the same cooling principal as typical air conditioning units in homes across the world. Using the refrigeration system and passing compressed air through a heat exchanger, the air is cooled to approximately 3°C/40 °F. As the air cools, water droplets begin to form in the air due to condensation much like the water droplets that form on the outside of a cold drink. The moisture laden air then undergoes a mechanical separation process where the liquid or “condensate” is separated from the air stream. The air is then rewarmed using the incoming air which lowers the relative humidity of the air and traps any remaining moisture in a vapor form.

Product Lineup

COOL Series – Non-Cycling Dryers

Pneumatech COOL Series – Non-Cycling Dryers
Pneumatech’s reliable and robust COOL range is a cost-efficient solution to lower the presence of moisture in your compressed air system.
The COOL range offers a stable pressure dew point as low as 5°C, ensuring ISO 8573-1 class 5 quality.

Cycling Dryers – AC VSD Series

Pneumatech Cycling Dryers – AC VSD Series
Pneumatech extends its premium AC refrigerated dryer range with variable speed technology in order to match the energy consumption to the actual compressed air demand.
The Variable Speed Drive (VSD) matches the energy consumption to the actual air demand, hereby reducing energy costs up to 70%, compared to traditional dryers.
The range is equipped with rotary compressors and R410A refrigerant. This combination is up to 30% more energy efficient; requires 19% less refrigerant charge and is 100% compliant to future European legislation

AC HP Series – high-pressure refrigerated dryers

Pneumatech AC HP Series – high-pressure refrigerated dryers
Pneumatech offers an extensive range of high pressure refrigerated dryers for applications up to 50 bar / 725 PSI. Solutions for pressures up to 350 bar / 5075 PSI are available on request.The heavy duty steel construction makes the heat exchanger extremely reliable and long lasting for high-pressure applications.The highly-efficient water separator guarantees water separation up to 150% of the nominal flow.

AC Series – Cycling Dryers

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

  • 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)

AD Series – Non-Cycling Dryers

Pneumatech AD Series - Non-Cycling Dryers
Pneumatech uses quality heat exchangers with integrated moisture separators to prevent pressure losses in the system.All Pneumatech refrigerated dryers come with standard zero-loss drains that save you money by preventing the loss of valuable compressed air associated with other types of drains.AD dryers utilize a hot gas bypass valve to prevent the ice from forming in the dryer during periods of low flow.The AD125-1250 range is equipped with rotary compressors and R410A refrigerant. 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.
