Clean Air…

Removing oil, particles and moisture from compressed air in the most demanding conditions, Atlas Copco’s SD membrane dryers with pre-filters eliminate the results of low quality air at the lowest energy cost. Thanks to their pioneering Advanced Fiber Technology, SD dryers ensure the lowest pressure drop and purge air loss for the highest possible efficiency – saving you time and money through your production process.

... in Extreme Conditions

From small spaces to environments with fluctuating ambient temperatures, SD dryers can perform in a wide variety of harsh and critical conditions. SD dryers also come with different types of membranes, each with a range of performance, to offer you the exact air treatment you require.

All dryers are manufactured in accordance with Atlas Copco's Quality and Environment Management System. This system complies fully with ISO 9001 and ISO 14001. All Atlas Copco dryers are tested to perform under the most demanding conditions.

Performance In Harsh Conditions

Atlas Copco’s membrane dryers perform where others won’t:

• In small spaces

• In areas where flexible mounting is required

• In high vibration areas

• In widely fluctuating temperatures

Performance In Critical Conditions

SD dryers provide dry air in environments with strict safety or environmental requirements:

• In low flow environments

• In areas without electrical supply

• In areas with explosion proof requirements

• In noise sensitive areas

• In corrosion sensitive areas

A Choice of Performance: P and N range

SD dryers are offered with two types of membranes, each providing a different Pressure Dew Point Suppression (see Technical Data). This choice of performance ensures that regardless of your production environment and demands, there is an SD dryer to meet your needs.

The Atlas Copco SD dryer range includes the P and N model range, each offering 7 different size dryers

P RANGE: Ensures a suppression of 32°C (55°F), giving at the reference conditions an outlet air dew point of 3°C (40°F), similar to a well-designed refrigerant-type air dryer

N RANGE: Lowers the inlet dew point with 55 °C (100°F), giving a pressure dew point of -20°C (-5°F) at the reference conditions

Working principle

Atlas Copco’s unique SD dryer range ensures the lowest pressure drop and the lowest purge air use –providing real energy savings without compromise in production reliability and efficiency.

Advanced Fiber technology: Maximizing Efficiency

Atlas Copco’s membrane dryers contain thousands of hollow fibers with a pioneering inner coating. As wet compressed air enters, the membrane coating allows water vapor to permeate and collect between the fibers, while the dry air continues its journey. Compared to conventional membrane dryers, the unique coating increases the separation efficiency between water vapor and oxygen and nitrogen, giving an unprecedented low air leakage and the lowest purge air loss
