Innovative, compact dryers for superior efficiency and reliability

The Kaeser Modular Membrane Dryer (KMM) produces pressure dew points to -40°F. It is perfect for small to medium compressed air systems. KMMs do not require electricity or cooling water, which simplifies installation even in existing systems. They are particularly effective in reaching low pressure dew points when used with a refrigerated dryer and installed at the point of use.

Outstanding Membrane Design

Super-Fine Membrane Fibers

 N/A Compared to conventional membrane fiber dryers, the fibers in the Kaeser membrane module many more fibers that are significantly finer, thereby increasing their surface area. In turn, this delivers superior drying performance compared to conventional designs. The high mechanical stability of the membrane fibers also helps ensure superior performance.

Flow Concept

 N/A The hollow membrane fibers consist of a highly porous support layer and an internal, water-permeable separation layer. The pressure differential between the moist compressed air outside the fiber and the almost atmospheric flow of purge air through the center encourages water molecules to permeate through the fiber wall. As a result, the pores of the support layer always remain permeable.

Efficient Drying

 N/A The spiral helical structure of the fibers in the inner chamber of the dryer module means that the module is now shorter, yet has the same drying capacity as previous, longer models – while still achieving a greater active membrane surface area per unit of volume. The helical fiber structure also promotes even distribution of air around the fibers and encourages the movement of water molecules.

Function of the Membrane Dryer Module

Function of The Membrane Dryer Module

 N/A Moist compressed air flows into the module casing, where it comes into contact with the membrane fibers. A minimal amount of this now dry compressed air is used as purge air and is drawn upwards around the fibers and expands to atmospheric pressure. The resulting increase in volume increases the air’s water retention capacity. In combination with with the selectivity of the membrane, the differing water content of the purge air flow and the flow of air to be dried (both flowing in opposite directions), allows water molecules - almost exclusively - to diffuse through the fiber wall. There are separate outlets for the dried compressed air and the purge air.

Additional Information

Additional Information

 N/A Efficiency and Dependability

The KMM dryer provides many advantages over conventional membrane dryer models. The "inflow" design ensures outstanding drying results by effectively removing moisture, enhancing pressure stability and reducing pressure differential. The welded aluminum housing and epoxy powder coating provide durability in harsh environments. Its lightweight design requires no additional support structure, and the space-saving modular design connects easily to prefilters and afterfilters. In-line filters are recommended with a KMM to prevent contaminants from reaching the sensitive membrane fibres.

Note

Note

 N/A Use inlet air temperature if the air entering the dryer has not been dried upstream (air is saturated). If air has been dried (e.g. in a refrigerated dryer) use the dew point temperature of the inlet air.

Flow capacities are at 100 psig. Capacities are established in accordance with CAGI Standard ADF 700; Membrane Compressed Air Dryers - Methods for Testing and Rating. Larger capacities, alternate pressures, and dew points consult factory.

Dimensions and weights are for reference only.

Specifications are subject to change without notice.

The standard one year warranty is extended to three years when the dryer is installed with an optional pre-filter package. To keep the warranty in effect, filter elements must be replaced at six month intervals and the drain mechanism yearly.
