Energy-efficient rotary drum dryers

A drum type heat of compression dryer offers an energy-efficient way to produce dry air. It’s a perfect match for your oil-free screw or centrifugal compressors. It uses the heat generated in the compression process to regenerate the desiccant. This heat is typically wasted in twin tower drying technologies. Our rotary drum dryers completely avoid the loss of compressed air. They need a minimal amount of power to achieve very low dew points

  • MDG rotary drum dryer 450l/s - dew points of  -40°C/F and lower
  • MD  rotary drum dryer from 200 to 4000 l/s – dew points of -25°C/-13°F 
  • ND rotary drum dryer from 300 to 4000 l/s – dew points to -45°C/-49°F 
  • A Variable Speed Drive (VSD) dryer version is available to match the lower power consumption oil-free VSD compressors

Key features

Cut down on energy costs

The MDG, MD & ND rotary drum dryers have zero purge by design, eliminating the waste of compressed air associated with twin tower dryers. Low pressure drop too

Increased efficiency

The ND rotary dryer controller carefully manages the heating power to achieve the requested performance. Smart and efficient heating

Smart AIR solution

A complete, energy-efficient solution requires an integrated system of air compressors, filters, dryers and controllers. Our range of compressed air products is fully optimized to work together

Minimal space requirements

Compact and space-saving, especially when compared to oil-lubricated systems which require filtration

Protecting our environment

No harmful Freon or CFC’s in the MD & ND rotary drum dryers. 95% of all components are recyclable

Food & beverage standard

ISO 22000 certification for our oil-free production facility in Antwerp, Belgium. The food safety management system is applicable to all our Z type class 0 oil-free air compressors and related dryers and filters
