The BAUER B-NITROX MEMBRANE system
Nitrox optimised compressor: Compressor block optimised for high oxygen content and temperature monitoring of cooling air and in the final separator
Oxygen content independent of ambient temperature: Constant cooling of the membrane to ensure optimum efficiency at all times
Small footprint: Screw compressor, refrigeration dryer, filter and membrane unit are installed in a compact housing
B-MEMBRANE is BAUER's nitrox membrane system. This compressor system enriches breathing air with an increased oxygen content of up 40%.
With B-NITROX, BAUER is the only manufacturer in the world to offer a complete nitrox system certified by the TÜV. True to BAUER's uncompromising safety philosophy, all components have been perfectly matched.
The B-NITROX unit has been designed for reliable nitrox supply to stationary, professional diving centres, safari boats, live-aboards, yachts and cruise liners as well as for commercial diving missions.
The legislator has issued clear regulations, as the compression of gases requires a specific degree of tested safety.
This is an important consideration with regard to product liability in the event of accidents (in particular for tour operators and hotels who run diving centres on their sites).
The components of the BAUER B-NITROX MEMBRANE system
All the information you need at your fingertips!
Low Pressure compressor
Screw compressors have an intake pressure of approx. 10 bar, required to supply the oxygen membrane in the system. The screw compressor with ultra-efficient “rolling profile” is a BAUER in-house product
Refrigerant dryer
Refrigerant dryer for efficient cooling and condensate separation. Enables oxygen mixture to be produced irrespective of the ambient temperature: the continuously cooled membrane delivers optimum efficiency at all times Filter system reliably removes oil and particulate to protect the membrane from harmful influences and extend its service life.
Membrane
The oxygen membrane boosts oxygen content by separating N₂ from the breathing air. The oxygen content of the breathing air can be set at any level between 21% and 40%1
1 Maximum oxygen level depends on the specifications of the selected membrane system.
Other voltages/frequencies
All electric motors are available with other voltages and frequencies on request.
Paint finish/Special paint finish
All frame parts of BAUER compressors are finished with a sophisticated powder coating. Read more
