Pure nitrogen generator N-GEN

processPSA

The N-GEN nitrogen generators 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 NG nitrogen generators use two molecular sieve beds, which alternatively switch between the adsorption and the regeneration phase Characteristics operating pressure - 6-10 bar operating temperature range - 5 to 35 °C - - - - - - ambient air temperature range - up to 40 °C dew points (atmospheric) - < -40 °C capacity - 3 to 442,5 Nm3/h purity - up to 99,999 % STANDARD EQUIPMENT • Set of External Feed Air Filters • Adsorber Vessels in Carbon Steel • Long life Pneumatic Valves • Internal Piping & Fittings zinc plated carbon steel • Nitrogen flow Regulation • Control System with SIEMENS PLC • WebControl
