Features:

SNC-1 nitrogen purifier:
1) Process: catalytic conversion using hydrogen for de-oxidization
2) Technical parameters:
a) Inlet nitrogen purity: ≥98%
b) Oxygen content: ≤5ppm
c) Dew point: ≤-60°C
d) Hydrogen content: ≤0.5%

By using high quality catalysts that do not require any additional activation, our deoxidization process is highly efficient. Our SNC-1 is suitable for industrial applications that require high-purity nitrogen, but at the same time, be able to tolerate higher levels of hydrogen gas residual content.

SNC-2 nitrogen purifier:
1) Process: catalytic conversion using hydrogen for de-oxidization,
followed by removal of hydrogen
2) Technical parameters:
a) Inlet nitrogen purity: ≥98%
b) Oxygen content: ≤2ppm
c) Dew point: ≤-60°C
d) Hydrogen content: ≤5ppm

Similarly, this process uses high quality catalysts and hydrogen gas to produce high purity nitrogen, and followed by the removal of residual hydrogen gas. As a result, SNC-2 is suitable for processes that can only accept minimal residual contents of oxygen and hydrogen gases.

SNC-3 nitrogen purifier:
1) Process: oxygen removal through chemical reaction, using
de-oxidants
2) Technical parameters:
a) Inlet nitrogen purity: ≥99.9%
b) Oxygen content: ≤1ppm
c) Dew point: ≤-60°C
d) Hydrogen content: ≤5ppm

When the oxygen content of the supplied nitrogen is less than 1,000ppm, we recommend our SNC-3 that uses high efficiency de-oxidants to remove oxygen. With this process, high purity nitrogen can be produced without any residual hydrogen gas content. However, this process requires the de-oxidization device to be periodically regenerated using hydrogen gas and heat.

SNC-4 nitrogen purifier (oxygen removal with carbon):
1) Process: oxygen removal using activated carbon
2) Technical parameters:
a) Inlet nitrogen purity: ≥99.5%
b) Oxygen content: ≤5ppm
c) Dew point: ≤- 60°C
d) Hydrogen content: ≤5ppm

When the oxygen content of the supplied nitrogen is less than 5,000ppm, we recommend using our SNC-4 that uses high efficiency activated carbon de-oxidants to remove oxygen traces. Thus, high purity without hydrogen is obtained. However, this process also requires the periodical replenishment of the used activated carbon.
