Product catalog summary
Introduction to Membrane Dryers:
The KMM Series membrane dryers by KAESER are designed to efficiently dry compressed air with a flow rate at the inlet of up to 4.40 m3/min. These dryers are essential for removing moisture from compressed air to prevent equipment breakdowns and reduce maintenance costs.
Why Dry Compressed Air?
Compressed air naturally contains water vapor, which can condense and cause damage to equipment. Drying the air prevents condensate accumulation, ensuring reliable operation and minimizing maintenance.
Membrane Dryer Module Functionality:
Moist air enters the module, contacts membrane fibers, and a portion is used as purge air. This air expands, increasing its moisture retention capacity, allowing water molecules to diffuse through the fiber wall. Separate outlets exist for dried air and purge air.
Decentralized Drying and Dependability:
The KMM design offers advantages over conventional models, including effective moisture removal, pressure stability, and reduced differential pressure. The 'Flow' concept ensures efficient air drying and long service life.
Key Features of KMM Dryers:
  • Efficient Helix Structure: The helix-wound membrane fibers increase surface area for air contact, enhancing drying efficiency.
  • Precision Purge Air Nozzle: Reduces operating costs by diverting only necessary purge air volume.
  • Energy-Saving Purge Air Stop Valve (Optional): Prevents unnecessary purge air flow during downtime, enhancing reliability.
  • Super-Fine Membrane Fibers: Densely packed fibers provide superior drying performance and mechanical stability.
  • Condensate Drainage Without Pressure Loss (Optional): The ECO-DRAIN 31F ensures efficient drainage and monitors service intervals.
  • Efficient KAESER FILTER (Optional): Protects membrane fibers from contamination, ensuring minimal pressure differential.
Technical Specifications:
The document provides detailed specifications for various KMM models, including inlet volume, purge air volume, dimensions, and suitable pre-filter models. Correction factors for deviating operating pressures are also included.
Fields of Use:
Membrane dryers are suitable for limited space or mobile operations, seasonal operations at sub-zero temperatures, and drying small air volumes directly at air-consuming equipment.
Compressed Air Quality Classes:
The document outlines air quality classes according to ISO 8573-1, detailing requirements for pressure dew point, liquid water concentration, solid particles, and oil concentration.

Membrane dryers KMM series-2

The atmospheric air drawn into a compressor is a mixture of gases that always contains water vapour. The amount of water vapour air can carry varies and is mostly dependent on temperature. When air temperature rises – as happens during compression – the air's ability to hold moisture increases also. When the air is cooled, its capacity to hold moisture reduces, which causes the water vapour to condense. This condensate is then removed in the centrifugal separator, or the air receiver, downstream from the compressor. Even then, the air can still be completely saturated with water vapour. This...

Membrane separation layer KMM – Eight decisive advantages 1 ‘Flow’ concept Energy-saving purge air stop valve (Option) Porous support layer To avoid unnecessary flow of purge air, the solenoid stop valve on the purge air outlet can be set to close during times when there is no compressed air demand. Furthermore, the valve provides unrivalled reliability and operated perfectly for well in excess of 1 million switching sequences under rigorous testing conditions. Each hollow membrane fibre consists of a highly porous support layer and an internal separating membrane layer that is permeable only by...
