Cryogenic liquid Nitrogen purifier – ULTRAL LN2
An exclusive Air Liquide solution for the direct purification of liquid nitrogen to the level of ppb
ULTRALTM LN2 is a purifier specially designed to purify liquid nitrogen upstream of a storage unit in order to act as backup for example for a gaseous nitrogen generator (e.g. APSATM). The adsorption technology employed is used to eliminate impurities such as CO, O2, H2 down to ppb level. The purification principle is based on cryo-trapping or the chemisorption of impurities on a bed of high performance adsorbent.
Key benefits
- Cost-effective solution for purifying liquid nitrogen directly
- Easy-to-use manual purifier: only one operator is needed!
- Adsorbent bed that can be regenerated in only 9h
- >3 µm particle filtration at purifier output
