Membrane Nitrogen & dry Air generator with integrated direct drive Scroll compressor. Electronic controlled.


The NitroGen series NGA CASTORE XL iQ are Membrane Nitrogen and dry air Generators. They are engineered to transform standard compressed air into a safe, regulated supply of Nitrogen up to 40 L/min with a purity up to 99.8%. A channel can provide up to 60 L/min of compressed, dry and regulated air. This NGA series is equipped with a scroll built-in oil less compressor with inverter technology. The new iQ series is equipped with the innovative direct drive motor-compressor system that result in lower noise than the previous version. The exclusive electronic flow control combined with the compressor control by the inverter allows to generate Nitrogen with a higher purity using a maller volume at less pressure of air which results in reduced energy costs and increase the life time of the compressor. Continuous control of the operating parameters of Nitrogen allows to maintain the system at its maximum efficiency. The CASTORE XL iQ with its dual Nitrogen and Air outlets has been developed to meet specific requirements in term of gas, flow, purity and pressure in LC-MS applications. It can be used for the evaporation of solvents in samples being analysed.
