Variable frequency energy-saving system - S standard series

The variable frequency energy-saving system has been awarded multiple national patents (patent numbers: 2011120271724.1/201420830501.8/201420830476.3). It is a variable frequency energy-saving technology configuration specifically designed for compressors with medium and low loads. Without altering the original system, it upgrades the compressor's variable frequency. By utilizing advanced vector control technology combined with our proprietary PID algorithm, precise control of the compressor is achieved, ensuring zero upgrade risks and optimal energy savings.

This system is suitable for all screw, piston, vane, and centrifugal compressors. It adopts a PLC control system, integrating the control and variable frequency control of the air compressor. Equipped with its own air compressor control system, when connected to the air compressor, there is no need to change the original wiring. Even if there is a problem with the system, you can still use the original mains frequency control, ensuring that your variable frequency modification carries no risk. After modification, the air compressor differs from the original factory variable frequency air compressor only in the motor.

The variable frequency energy-saving system employs variable speed control technology, allowing the compressor's displacement to perfectly align with the user's air consumption, thus completely eliminating the waste of 45% of rated power during unloading. Utilizing advanced PLC and PID control adjustments, the system can maintain pressure within a range of ±0.01 MPa, consistently operating at a constant pressure of 0.6 MPa, thereby achieving greater energy savings. For every 0.1 MPa decrease in operating pressure, energy consumption can be reduced by 7%, resulting in a direct energy saving of 14%. Additionally, leakage in the compressed air system is significantly reduced; for instance, leakage at 0.6 MPa is approximately 15% less than that at 0.7 MPa
