Reliable nitrogen supply

Low to medium purity, on demand

The PMNG 4-40 HE provides on-site nitrogen with purities from 95% to 99.5%, combining the convenience of membrane technology with the reliability of a steady, self-sufficient supply.

Lower Air & Energy Use

Efficiency that saves

Built with high-efficiency membrane technology, the PMNG 4-40 HE uses up to 35% less air than standard membrane generators, helping reduce energy consumption and operating costs.

Space-saving & easy

Compact & plug-and-play

Designed to fit into tight spaces, the compact PMNG 4-40 HE comes ready to install, with quick commissioning, easy purity adjustments, and various models to match different nitrogen needs.

PMNG 4-40 HE Membrane Nitrogen Generators

The PMNG HE revolutionizes the cost-efficiency of in-house nitrogen production, using 35% less air on average than other membrane generators. This results in lower energy consumption, reduced operational costs, and a smaller environmental footprint.

 

Designed for ultimate convenience, the PMNG HE is a true all-in-one solution that’s operational as soon as it’s connected to your compressor—no need for external process vessels or filtration.

 

With its plug-and-play setup, the PMNG HE is simple to install and operate. The intuitive Purelogic Touch controller allows for easy purity adjustments and offers advanced options for control, monitoring, and connectivity.

 

Additionally, the PMNG HE is both quiet and compact. Its low noise levels make it suitable for installation right at the point of use, and its efficient design delivers up to 43% more flow within the same small footprint.
