Refrigerant Compressed Air Dryer
High-Pressure Non-Cycling Refrigeration Dryers
Reliable High Quality Air for Demanding Environments
Maximum reliability at working pressures up to 45 barg
CompAir high-pressure refrigeration dryers deliver safe and constant quality, dry compressed air for various demanding environments such as PET bottle blowing, water jet cuts and aeronautical valves, in ambient temperatures of up to 50°C. Delivering consistent dew point control of +3°C for reliable and dry compressed air, this range of ten robust, compact and space-saving dryers provide maximum reliability at flow rates of between 88m3/h to 1, 200m3/h (at a nominal pressure of 40 barg).
Fully integrated three in one stainless steel heat exchangers offer reliability and long life. At the same time, energy efficiency is increased by 10% over previous models, and CO2 footprint is reduced with the use of the new R513A refrigerant. High-pressure non-cycling refrigeration dryers from CompAir – efficiency and reliability by design support the sustainability of our product and customer operations.

High-Pressure Non-Cycling Refrigeration Dryers
A refrigerant compressed air dryer removes moisture from compressed air by cooling it, condensing the water vapor, and separating the liquid from the air stream.
A high-pressure non-cycling refrigeration dryer is specifically designed to operate at elevated pressures while running continuously (the refrigeration compressor does not cycle on/off).
🔧 How It Works
Hot, moist compressed air enters the dryer.
Air passes through an air-to-air heat exchanger (pre-cooling stage).
It then moves through a refrigerant-based evaporator, where temperature drops (typically to ~35–40°F / 2–4°C).
Water vapor condenses into liquid.
A moisture separator & drain system removes the condensate.
Dry, cool air exits the system.
⚙️ What “Non-Cycling” Means
The refrigeration compressor runs continuously
Capacity is controlled via:
Hot gas bypass valve
Refrigerant modulation
Ensures stable dew point
Ideal for steady load conditions
🚀 High-Pressure Capability
High-pressure models are built for:
200–725 psig (or higher depending on design)
Applications like:
PET bottle blowing
Aerospace systems
Military applications
High-pressure testing systems
They use:
Reinforced heat exchangers
Heavy-duty separators
Pressure-rated components
