How it works
-
Oxymat A/S uses two columns with molecular sieves to ensure continuous production.
-
Dry compressed air is blown through a valve to the vessel where the pressure is built to reach 5 to 7 bar(g). Nitrogen is tied to a molecular sieve during the building of pressure, and the oxygen is allowed to pass through to the accumulation tank.
- While pressure is build in one vessel, the second remains without pressure.
- A part of the produced gas is used for regeneration of the molecular sieve.
-
For Oxygen, Zeolite type 13X is used. The molecular sieve is fully regenerative and has a life span on to 40.000 operation hours.

-
Compressed air system (Air compressor, Refrigeration dryer, Air receiver & Filters).
-
PSA skid
-
Oxygen receiver
-
Oxygen boosting & Filling Station (optional)
Optional supplies
-
Panel Display with electro galvanized sensor
-
Touch Screen with zirconium sensor
-
GSM modem for touch Screen
