KOFLOC Corp.
KOFLOC NEII Series Large Nitrogen Gas Generator

Manufacturer: KOFLOC Corp.
Model: NEII series
Gas Generators
We provide products for generating various gases from the air and water around us, such as nitrogen gas, oxygen gas, ozone gas, clean dry air and hydrogen gas generators.
N₂ Gas generators

The nitrogen gas generator supplies high-purity nitrogen gas (95 to 99.999%) by extracting nitrogen gas from the air. As compared with methods using cylinders or liquid nitrogen, this product, which enables users to obtain nitrogen gas onsite, can save the cost and effort of management and operation, and reduce CO₂ emissions associated with transportation.
NEⅡ Series
The NE-Ⅱ series makes compact cabinet design with a generating volume of 20-180 Nm3/h possible.
Process improvements have also increased ni trogen generat ing volume by approximately 36.5% compared to the previous series.

*1 N2 purity is N2 (nitrogen) + Ar (argon) levels.
*2 Values obtained under environmental conditions of 20°C surrounding temperature and 60% relative humidity (RH) are converted for atmospheric pressure of 0°C. The amount of gas that can be produced may decrease due to surrounding temperature and humidity.
*3 The dew point is atmospheric dew point after stabilization.
*4 The above compressor output is a representative value from our recommended compressors. For details, please contact relevant staff at our company.
*5 The TYPE55K case is bisected. The two parts must be connected at the installation site.
* TYPE11/15/22 come with caster wheels. TYPE37/55 do not have caster wheels attached.
* For overseas specifications or special specifications not listed in our catalogue, please contact relevant staff at our company.
* Product improvements may lead to specification changes.
