Atlas Copco Begins Production of MDG Rotary Drum Dryer

After years of testing and development, Atlas Copco, a leading provider of sustainable productivity solutions, will begin production of a groundbreaking new air dryer technology by the end of this year. Unlike other dryers in the industry, the MDG rotary drum dryer is a revolutionary technology guaranteeing a stable pressure dew point (PDP) of -40 °F, at almost zero energy cost.

The MDG rotary drum dryer guarantees a stable PDP of -40 °F.


The MDG air dryers deliver cost-effective dry and oil-free air, with incredible power efficiency. They have a total power consumption below 0.2 kW in all operational conditions. Its simplified design takes up less floor space, has no heating elements, no blower and no loss of compressed air. With fewer moving parts, the dryer requires less maintenance, while offering more reliability than other dryers with -40 °F PDP performance.

“With the MDG dryers we now can provide the ultimate energy-efficient solution for customers who are looking for high quality of compressed air, and who are interested in the lowest total cost of ownership,” said Philip Ernens, Atlas Copco Oil-free Air division’s president.
