Cryogenic Helium Purifier – ULTRAL He

A cost-effective alternative to Getter-type purifiers for purifying gaseous Helium to sub-ppb.

ULTRALTM are cryogenic purifiers with a flow capacity range of  5 to 650 Nm3/Hr that offers continuous and reversible purification of Helium for very high purity applications.

ULTRALTM He is a purifier application specially designed for the purification of gaseous Helium. The adsorption technology employed is used to eliminate impurities such as CO, CO2, H20, CH4 and including the normally difficult to remove N2 down to sub-ppb level. The purification principle is based on the reversible cryo-trapping of impurities on a bed of high performance adsorbent.
