Even traces of impurities may cause malfunction of helium process plants with expensive consequences. Contamination plugging, for example, can shut down cryoplants for a long time.
The multi-component detector is used to monitor the purity of the helium in the system. The use allows a high helium quality, the reliable operation of the system and an optimal, cost-saving use of cleaners. It is possible to measure humidity and nitrogen. With the additional stage of a pyrolyser unit it is also possible to detect hydrocarbons and aerosols. Other elements can be offered on demand.
The cryogenic adsorber is recommended for clean-up of the helium gas in a liquefier or refrigerator system which has been opened and exposed to the atmosphere.
