In Built PERFECT AIR COMPRESSORVariable Frequency Drives (VFD) A xed speed compressor operates on a load unload band of at least 10 psi around the working pressure whereas with PERFECT 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 For compressed air systems with uctuating demand pattern, giving a fast return on operating pressure. there is 1% power saving. In a xed speed compressor with Star-Delta starter, starting current is as high as three times the full load current (FLC). With PERFECT 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. investment. In-Built PERFECT 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 loadunloa
