Refrigerated
General Industrial Drying
Atlas Copco refrigerated dryers cool compressed air so moisture condenses and can be separated and drained.
Atlas Copco Dryer Selection Guide
Atlas Copco Air Dryer Buying Guide
Atlas Copco offers refrigerated, desiccant and membrane compressed air drying technologies across a broad range of air-quality requirements. The right choice depends on pressure dew point, operating conditions, airflow and lifecycle cost.
Quick Answer
Choose an Atlas Copco refrigerated dryer for most indoor general-purpose systems requiring a pressure dew point near 37°F. Choose an Atlas Copco desiccant dryer when the process requires significantly drier air, including common -40°F applications or colder conditions.
Brand and Product Overview
Desiccant
Low-Dew-Point Drying
Atlas Copco desiccant systems use adsorption and regeneration for very dry compressed air.
System Design
Integrated Treatment
The final system should include correct prefiltration, drains, downstream filtration and condensate management.
Air Dryer Selection Guide
Choose by Application and Dew Point
| Application Need | Recommended Starting Point | Why | What to Verify |
|---|---|---|---|
| Indoor general plant air | Atlas Copco refrigerated dryer | Efficient moisture control near a +3°C / 37°F pressure dew point | Corrected CFM, voltage and ambient rating. |
| Outdoor or freeze-sensitive piping | Atlas Copco desiccant dryer | Lower pressure dew point reduces condensation and freezing risk | Select below the coldest expected line temperature. |
| Very low dew point | Atlas Copco desiccant or specialized dryer | Desiccant systems can support significantly lower dew points | Confirm exact model, regeneration method and filtration. |
| Compact point-of-use application | Atlas Copco membrane or compact dryer where appropriate | Small footprint and no refrigeration circuit | Confirm purge loss, inlet filtration and required dew point. |

Atlas Copco Air Dryer Buying Guide FAQs
What types of air dryers does Atlas Copco offer?
Atlas Copco offers refrigerated, desiccant, membrane and specialized drying technologies.
What dew point does an Atlas Copco refrigerated dryer provide?
Many Atlas Copco refrigerated dryers target approximately +3°C or 37°F under rated conditions.
When should I choose an Atlas Copco desiccant dryer?
Choose desiccant drying for low dew point, freezing conditions, instrumentation or moisture-sensitive processes.
How do I size an Atlas Copco air dryer?
Use maximum airflow and the exact model correction factors for pressure, inlet temperature and ambient temperature.
Do Atlas Copco desiccant dryers need filters?
Yes. Upstream filtration protects the desiccant, and downstream filtration may capture dust.
Should I choose by nominal CFM alone?
No. Compare corrected capacity, dew point, pressure drop, controls, maintenance and energy use.
