ENERGY SAVING - THE CONSERVE WAY

In-Built SAI AIR COMPRESSOR Variable Frequency Drives (VFD)

Matches compressor output with demand by varying motor speed. The power consumption reduces in line with the reduction in demand. Helps in eliminating the frequent load-unload cycle & also the wasted power from the energy bill. A fixed speed compressor operates on a load unload band of at least 10 psi around the working pressure whereas with SAI AIR COMPRESSOR VFD, compressor can be operated within a band of 2 psi. Since the compressor is not operated under higher than working pressure requirements, there is substantial energy saving. For every 2 psi reduction in operating pressure, there is 1% power saving. In a fixed speed compressor with Star-Delta starter, starting current is as high as three times the full load current (FLC). With SAI AIR COMPRESSOR VFD, starting current is less than FLC. This helps to avoid using heavy rated components like fuses, MCCB, cable size, generator rating, isolate etc. For compressed air systems with fluctuating demand pattern, giving a fast return on investment.
