  Features

The DRYPOINT M Principle

The DRYPOINT M is a super compact membrane dryer that dries the air down to the required dew point while adjusting itself to the ambient conditions.

  • Twist 45 Technology: highest possible performance with 45° wound fibers
  • Maximum Reliability: even in the toughest environments
  • Highest Performance: achieves dew point in 10 minutes or less
  • Maintenance-Free: no moving parts, reliable even in mobile applications
  • Perfect Design: small footprints in several configurations

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. Therefore, drying systems should be designed around the specific application.

As is required for all drying methods, high quality pre-filtration is essential for the reliable function of a membrane dryer. CLEARPOINT filters from BEKO Technologies go perfectly with the DRYPOINT M membrane dryer, and are integrated into DRYPOINT M PLUS series housings.

Along with filtration, compressed air drying contributes significantly to the enhancement of process reliability. Water vapor in compressed air systems leads to accelerated corrosion and represents a permanent risk with regard to sensitive equipment, as well as increased wear and tear on production process machinery.


How does it work?

(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 fibres 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 dispersed into a higher volume. The dry purge air is led via the outside of the membrane fibres.

(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 in the hollow-fibre 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 fibres, the TWIST 45 technology.

(5) The dry compressed air leaves the membrane element.

(6) The humid purge air is released into the environment.
