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 manual cryogenic purifier that can be used to purify liquid nitrogen straight off a tanker truck during container stripping or from another source for applications of very high purity. 

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.
