  • Nitrogen generators N-GEN – PSA

    The nitrogen generators N-GEN extract the available nitrogen in the ambient air from the other gases by applying the Pressure Swing Adsorption (PSA) technology. During the PSA process compressed, cleaned ambient air is led to a molecular sieve bed, which allows the nitrogen to pass through as a product gas, but adsorbs other gases. The sieve releases the adsorbed gases to the atmosphere when the outlet valve is closed and the bed pressure returns to ambient pressure. Subsequently, the bed will be purged with nitrogen before fresh compressed air will enter for a new production cycle. In order to guarantee a constant product flow, N-GEN nitrogen generators use two molecular sieve beds, which alternatively switch between the adsorption and the regeneration phase. Industrial nitrogen gas can be also produced by separation of gaseous air using membrane technology or fractional distillation of liquid air using cryogenic technology. Decision on production method depends on required purity, volume and regime of consumption.

Containers and SKIDS

Our speciality is the design and construction of compressor stations according to specific requirements of our customers. We carry out measurements of production process requirements on the basis of which the compressed air station project is made. Professional approach to the project ensures reliable operation, maximum space utilization and high energy performance. Only high quality devices and materials are used. We and our Partners manufacture a wide range of compressed air and gas treatment products (cyclone separators, filters, dryers, condensate drains, gas generators, pressure vessels…). Our industrial engineering division is able to integrate standard or custom made products into a skid/container based packages according to specific project requirements. Skids can be designed according to variety of design codes (PED, ASME, DNV, ABS, NR13, AS1210 …).
