National Library of Hungary

After protecting the National Library of Israel from fire, we are now commissioning the N2 Oxygen Reduction System to protect the National Library of Hungary (National Széchényi Library NSZL). 19 large archives containing library documents of the Hungarian cultural heritage will be actively protected from fire 24/7, using the most advanced technology to produce oxygen-reduced air: #ADOX #VPSA nitrogen generators. The oxygen analysis, on the other hand, is carried out by latest generation of Isolcell optical oxygen sensors, the only ones certified #SIL-3 according to EN IEC 61508.
