Key Benefits of Grasys Membrane Nitrogen Generation Units

Each Grasys nitrogen generation unit is based on a state-of-the-art membrane of the latest generation. Due to testing and computer simulation of GRASYS high performance membrane modules based on the latest generation of nanomembranes, the unit parameters are achieved after a short warm-up period and maintained in a stable manner

Grasys nitrogen generation units are completed with ready-to-operate compressors from leading European and US manufacturers and factory-tested according to a special programme. This ensures long and reliable operation of the compressors and the units as a whole.

We offer to purchase nitrogen generation units on the most favourable terms! Our experienced specialists are always on hand to advise on prices, specifications, operating conditions, lead times, etc.

General Description

Membrane nitrogen generation units are the preferred option for producing gaseous nitrogen with a purity of up to 99.9% at system production capacities of up to 180 m³/h or lower purity at capacities of up to 5,000 m³/h. Where the nitrogen of a higher purity, from 99.95% to 99.9995%, is required, which cannot be achieved by membrane technology, the use of

The main components of the Grasys membrane units are the compressor unit, air treatment unit, gas separation unit and the GRASYS Intelligent Control-8 monitoring and control system. The gas separation unit consists of specially configured modules that generate nitrogen of the required purity from the atmospheric air.

GRASYS Intelligent Control-8 is a state-of-the-art, smart, multi-functional monitoring and control system that enables the automatic operation of Grasys units, including remote access and archiving, and integration into a superordinate control system.

By using the latest technology, Grasys nitrogen generation units are extremely reliable, with a membrane unit life of up to 180,000 hours of continuous operation.
