NeoCHROM NG series nitrogen generator

Features and benefits:

automatic pressure and flow display; automatic constant pressure and current control; nitrogen flow can be adjusted automatically to match demand;
advanced technology: membrane separation is used in the electrolytic cell; a PCAN support and precious-metal catalyst are used in the catalytic layer, providing high catalytic efficiency, high gas output and high nitrogen purity;
the electrolytic cell undergoes more than 100 hours of ageing testing at high voltage and current before delivery, improving its operational stability.
low moisture content of the generated nitrogen: membrane separation with ultrahigh molecular permeability and a metal-polymer drying device reduce initial moisture;
two adsorption systems are used, including a trace oxygen removal agent that requires no activation, further lowering the nitrogen dew point and improving purity;
easy operation: no need to transport or handle purification cylinders; simply switch the unit on to generate nitrogen. Continuous or intermittent operation provides stable nitrogen production without a reduction in flow.
safe and reliable: equipped with a sensitive and reliable automatic alkali protection device.
