Atlas Copco introduces the MDG rotary drum dryer that offers a stable pressure dew point (PDP) of -40°F. The MDG air dryers deliver cost-effective dry and oil-free air with a total power consumption below 0.2 kW in all operational conditions, according to the company. The 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.
