Compressed Air Dryers
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.

1. Refrigerant Compressed Air Dryer
A Refrigerant Air Dryer removes moisture from compressed air by cooling the air, similar to how an air conditioner works.
How it works
Warm compressed air enters the dryer.
A refrigeration system cools the air (typically to around 3–5°C dew point).
Moisture condenses into water droplets.
Water is separated and drained out.
Key Features
Pressure dew point: ~3°C
Low maintenance
Energy efficient
Ideal for general industrial applications
Common Uses
Manufacturing plants
Automotive workshops
Pneumatic tools
Packaging lines
2. High-Pressure Non-Cycling Refrigeration Dryer
This is a specialized refrigerant dryer designed for high-pressure compressed air systems.
Typical Pressure Range
Up to 45 bar / 50 bar / 70 bar depending on design.
Non-Cycling Meaning
The refrigeration compressor runs continuously, regardless of load.
Provides stable dew point and consistent performance.
Key Features
Handles high pressure air systems
Stable dew point
Simple control system
Suitable for continuous industrial processes
Applications
PET bottle blowing
Power plants
Oil & gas
High-pressure testing systems
3. Compressed Air Dryer (General Category)
A Compressed Air Dryer is a broad term for any system that removes moisture from compressed air.
Main Types
Refrigerated Dryer – most common, economical
Desiccant Dryer – very low dew point (-40°C to -70°C)
Membrane Dryer – compact for small systems
Why Dry Air Is Important
Prevents corrosion in pipelines
Protects pneumatic equipment
Avoids product contamination
Improves system reliability
✅ Quick Comparison
Type Dew Point Best For
Refrigerant Dryer ~3°C General industrial air
High-Pressure Refrigerant Dryer ~3°C High-pressure systems
Desiccant Dryer -40°C or lower Critical / moisture-sensitive processes
