Nitrogen generator NG-3H (integrated protective gas generator with cooling)
The protective nitrogen generator separates compressed air into nitrogen and oxygen. The
nitrogen produced is used for cooling the optics and as a protective gas for the process. Oxygen
is allowed to flow into the ambient and will prevent high nitrogen concentrations from
becoming hazardous for the operating personnel.
- Total air consumption (Vn)
about 10 m³/h
- Purity of N2
> 99 %
- N2 output rate (Vn) at purity 99 %
< 1.5 m³ at 6 bar
