The INMATEC PNC nitrogen technology produces nitrogen with a purity of up to 5.0 / 10 ppm (residual oxygen) and in quantities of 10,7 – 2.849,6 Nm3/h.

The INMATEC Pressure Swing Adsorption Process separates the nitrogen molecules from the oxygen molecules. You can now use high-purity N2 in a wide range of applications.

Latest Flow Technique and Innovative Rotator Engineering are reducing the demand of compressed air and lowering energy costs significantly.

The process optimizes the cycle times in the N2 production. In combination with compressors with optimized rotational speed the compressors air demand can also be significantly lowered.

Storage tanks are frequently used to provide extra filling capacity during peak periods. Ideally the storage pressure should be higher than the filling pressure, 300 bar storage systems are the most common. The storage systems can be used with most compressors and are best suited for automatic operation (e.g. ECC or auto start option). A full range of storage modules each can be combined with other modules for individual configuration.
