OF 90 Oil Free Series Screw Air Compressor

ELGi Oil free TechnologyELGi is one of the very few compressor companies to design and manufacture oil-free airends. With in-house oil-free technology, the compressors are engineered to deliver maximum uptime and reliability. ELGi's unique eta-V rotor design reduces pressure losses and increases stage efficiencies,leading to an optimized compressed air system.Optimized component layout of the OF series machine provides easy serviceability with reduced service time. Incorporating superior safety norms, the compressors have not only low energy losses and low air outlet temperatures but are also highly reliable and compact.All these advanced features integrated into one simple design that drives maximum Reliability and Uptime.Variable Frequency Drives (VFD)The ElGi CONSERVE VFD matches the compressor output to air demand by varying motor speed and hence the power consumption of the compressor reduces in line with the reduction in demand. The VFD eliminates frequent loadunload cycle and minimizes power wastage there by saving energy cost.A fixed speed compressor operates on a load unload band of at least 0.5 bar (g) around the working pressure whereas with ElGi VFD,compressor can be operated within a band of 0.1 bar (g). Since the compressor is not operated under higher than working pressure requirements, there is substantial energy saving. Approximately, For every 0.1 bar (g) reduction in operating pressure, there is 1% power savingIn a fixed speed compressor with Star-Delta starter, starting current is as high as three times the full load current (FLC).With ElGi VFD,starting current is less than the FLC. This helps to avoid using higher ratings of allied components like fuses, MCCB,cable size,generator rating,isolators etc.For compressed air systems with fluctuating demand pattern,return on additional capital investment due to energy saved can be within few months.Prices are customized and may vary.
