Beko MDp 100 Membrane Dryer

DRYPOINT^® MD | Membrane Drying

Membrane air dryers are a type of dryer that use permeable fiber technology and the process of de-humidification to dry compressed air streams to the required dew point of an application. The Compressed Air and Gas Institute advises us to dry only the compressed air that is actually being used, and to make it only as dry as the application truly requires. Membrane air dryers are perfectly suited for this type of point-of-use drying, are adaptable to various ambient conditions, and require no electricity.

Features & Benefits

How it works

1 The compressed air flows into the core tube of the membrane dryer.

2 | 2a In the filter element, it is diverted; filtered compressed air enters the hollow fibers of the
membrane element.

3 The purge air required for drying is continuously diverted in the outlet zone of the membrane element
and is atmospherically expanded through a defined nozzle opening. This purge air is significantly drier due
to the expansion, as the humidity contained in the compressed air is now distributed to a multiple of
volume. The dry purge air is led via the outside of the membrane fibers.

4 Two air flows with different moisture contents move in a reverse current through the membrane
element, only separated by the membrane wall. The humid compressed air flows inside the hollow
fiber membranes, and the dry purge air flows outside. As a result of the different moisture contents,
the humidity diffuses from the compressed air into the purge air. The drying process is highly efficient thanks to the controlled winding of the membrane fibers, the TWIST 45 technology.

5 The dry compressed air leaves the membrane element.

6 The humid purge air is released into the environment.
