Gas Purifiers
The HCPS and NCPS Gas Purifiers are stand-alone Systems offering in-situ Regeneration. Their Dual-Bed Design guarantees a continuous Supply of pure 9N Gas.
HCPS – Hydrogen Purifier
Continuous operating Hydrogen Purification System
The HCPS is an integration of two H2-Gas purifier-units and the associated heaters and sensors for automated gas purifying. The product is designed to purify hydrogen 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 hydrogen 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. During the reactivation process, the regenerating bed is heated and a small amount of purified hydrogen is run counter flow through the bed. This drives off all contaminants and leaves the bed ready to purify hydrogen 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. The complete regeneration cycle is SPS-controlled.

Technical Highlights
- Designed to replace Pd-diffusion gas purifiers or one-way cartridge systems
- Removes moisture, oxygen, carbon oxides, and others from hydrogen gas
- Continuous operating without changing of filters or opening of piping
- Residual oxygen and moisture less than 1ppb (9N)
- Operating without Pd-diffusion membrane
- Insensitive to power supply failures
- Insensitive to unstable gas qualities

Installation
The HCPS Purification System is a stand-alone system offering in-situ regeneration. The dual bed design guarantees a continuous supply of pure gas. No need to send a purifier back for regeneration or to install an expensive replacement cartridge. More importantly there is no need to interrupt your process. The pre-programmed controller knows when to switch to the fresh purifier and to regenerate the other.
The HCPS can be adapted easily to customers’ applications. Only a Hydrogen vent-line and an electrical power-supply of 800 Watt are needed. Standard VCR® fittings are used for connections of gas piping.

NCPS – Nitrogen Purifier
Continuous operating Nitrogen Purification System
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.

Technical Highlights
- Removes moisture, oxygen, carbon oxides, and others from nitrogen gas
- Continuous operating without changing of filters or opening of piping
- Residual oxygen and moisture less than 10ppb (8N)
- Insensitive to power supply failures
- Insensitive to unstable gas qualities
- Minimum dimensions
