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


NGA CASTORE XL iQ EVOQ is a Nitrogen Generator with Membrane technology. It is engineered to transform standard compressed air into a safe, regulated supply of Nitrogen up to 32 l/min with a purity up to 99.95% plus a second outlet of dry and clean air up to 50 l/min. A special carbon filter is used to remove VOC. The CASTORE XL iQ EVOQ with its dual Nitrogen and Air outlets has been developed to meet specific requirements in term of gas, flow, purity and pressure for Bruker EVOQ solutions. It can be used for LC-MS and the evaporation of
solvents in samples being analysed. The new iQ generators are equipped with an innovative direct drive motor-scroll compressor system (oil less) with inverter technology. The exclusive electronic flow control combined with the compressor control by the inverter allows to generate Nitrogen with a higher purity using a smaller 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.
