Energy Saving Control
The permanent magnet variable frequency air compressor provides 30-100% linear no-step volume control. According to tphe change of the customer's compressed air requirement, the power consumption can be automatically controlled, which can significantly reduce the operating cost by up to 35%.
Energy Saving By Constant Pressure
The figure shows the pressure comparison between ordinary air compressor and PM variable frequency air compressor. The ordinary air compressor will be frequently loaded and unloaded between the demand pressure and pressure 1.5kg higher, which will cost an extra 10.5% power consumption than PM variable frequency air compressor that stable in demand pressure (7% more power consumption per 1kg pressure increase). Moreover, it will cost 45% energy when the compressor is idling. Therefore, the constant pressure supply not only reduce electricity consumption, but also extend lifespan of the machine and eliminate the adverse effects of unstable pressure.
Frequency Conversion Start
he figure shows a comparison of several startup methods. It can be seen that the permanent magnet variable frequency is start slowly, and it is more stable than the soft start, completely avoiding current peaks. Operate variable frequency conversion after reach rated pressure, can make stepless adjustment through pressure detection, output constant pressure as required, eliminates the consumption of continual loading and unloading control.
