Description

The NCPS is an integration of two N2-Gas purifier-units and the associated heaters andsensors for automated gas purifying. The product is designed to purify nitrogen at ambient temperature. Power failures will not affect the viability of a purifier bed to remove contamination.

Contaminants, such as moisture, oxygen, carbon monoxide, carbon dioxide, and non-methanated hydrocarbons, are removed from the nitrogen gas to sub-ppb levels through chemisorption and oxidation. The purifier media is a specific mix of inorganic nickel silica.

A dual bed system is used to maintain continuous flow. One purification bed is online while the other is in regeneration or in standby mode. The regeneration cycle is SPS-controlled. During the reactivation process, the regenerating bed is heated and a small amount of purified hydrogen, which additionally has to be supplied, is run counter flow through the bed. This drives off all contaminants and leaves the bed ready to purify nitrogen gas. When the bed returns to ambient temperature, it is put in a standby mode and is ready to go back online when the sequence is complete.
