For some applications in process plants or e.g. for Laser Cutting a nitrogen gas supply with a pressure of up to 25 bar g at medium or high purities is needed. Onsite Nitrogen Generation Systems are an economical alternative to liquid nitrogen tank supply.

SK Engineering has developed a new arrangement suitable for such applications. The system consists of a compressed air supply, a membrane or PSA based generator and a special booster compressor. To avoid any contamination of the nitrogen product an oil-free booster version can be installed giving benefit in system reliability and minimum maintenance as well as nitrogen quality. The system is designed for continous operation. As an option a governing PLC is supplied with a customised interface to e.g. existing factory automation system.
