KOFLOC NEMH Series Large Nitrogen Gas Generator
Manufacturer: KOFLOC Corp.
Model: NEMH 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.
NEMH Series
The NEMH series boasts the smallest class installation area in the industry with a range of 60- 180Nm3/h and it has increased the nitrogen gas generating volume by approximately 10% compared to the previous model （NE series）. It is also fitted with our original energy-saving function, the “cylinder deactivation system” so energy-saving effects in line with usage volume can be anticipated and it can be used outside. increasing choices for installation site.

*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 Outdoor specification is signified by the suffix -OD after the model name.
*5 Figures in brackets are gas state under conditions of surrounding temperature: 30°C, humidity: 70%RH. This method of inscription is widely used throughout the air compressor industry.
*6 The above compressor output is a representative value from our recommended compressors. For details, please contact relevant staff at our company.
