The NGM+ 1-7 range is a highly efficient nitrogen generator range utilizing membrane technology. These generators are designed to produce nitrogen from compressed air for a variety of applications. Purities range from 95% up to 99.9% (residual oxygen contents of 5% up to 0.1%). The innovative design offers a cost efficient on-demand source of compressed nitrogen for oil and gas, food packaging, general blanketing, plastics, tire filling, and many other industries.
The generator consists of one or multiple high performant membranes that are used together to achieve the nominal inlet flow. This membrane setup ensures a maximum output of compressed nitrogen for a minimum input of compressed air, at a wide range of operating conditions.
Safe and efficient operation of the complete unit is monitored and controlled by the in house designed Elektronikon® unit controller.
In order to allow continuous operation for more than 15 years, these nitrogen generators are equipped with a 3-stage premium prefiltration system ensuring an inlet air quality of [1:-:1] according ISO8573-1:2010. This eliminates the risk of the membrane being damaged by low
The Nitrogen Generator makes use of Pressure Swing Adsorption (PSA) technology to produce nitrogen
by passing pre-treated compressed air through a vessel containing carbon molecular sieves (CMS). The
PSA process is inherently a batch process, as the adsorbent bed requires periodic desorption. In order to
secure steady flow, the Nitrogen Generator PSA systems contain two adsorbent vessels to provide
operational continuity. One vessel is active while the other one is inactive. At the end of each cycle, they
