■ VSD (Variable Speed Drive)
– Energy Saving System (ESS Project), which makes the air compressor stop at the unload time in order to produce the suitable air amount
– Minimize the unnecessary power transmission through the Inverter, which controls the rotor and motor speed depending on the demand of the compressed air
– Reduce the consumption power and cost at starting operation by decreasing at staring current
In order to produce the compressed air, air compressors spend around 70% of the total power consumption in the most of factories. The demand of the compressed air in the factory is significantly different depending on the various factors, such as the time, seasons, weather, and working environment. According to the influences by those factors, the production volume of the compressed air is also not stable. Therefore, air compressors unlimitedly repeat the load and unload operation depending on the fluctuation in the demand. During this process, air compressors consume the much more unnecessary power than what we expect. |
◎ The Best Cases of FORT-VSD
– High frequency of the rotation between load and unload
– High frequency and Remarkable change in the air consumption patterns
– Long operation in unload time
– Small capacity of the passive equipment
– Special environment with less pressure fluctuation
