Product Description

Product Description

Using permanent magnet frequency conversion speed regulation technology to achieve the ideal energy-saving effect:
You don't have to worry about complicated electrical installation and program- ming anymore with SUNWIN intelligent permanent magnet variable frequency screw air compressor. The product is assembled as a whole before leaving the factory, and it can work immediately as long as the main motor source is connected. The powerful intelligent controller continuously detects the pressure change of the air system and accurately changes the speed to ensure that the air compressor's exhaust volume is always consistent with the user's system demand. The response speed of the intelligent controller is calculated in milliseconds and the speed correction can be completed within 3ms, so that the outlet air pressure is accurately controlled within 0.1bar. Our built-in filter can ensure the safe and reliable operation of the inverter. During use, you do not have to worry about "harmonics" and "radio frequency interference" and other issues. The unique automatic energy optimization and energy saving function enables the inverter to accurately supply the lowest power to the motor according to the actual load of the motor, which not only saves 10% more power, but also reduces motor noise.

Cost comparison
SUNWIN permanent magnet variable frequency air compressor can accurately change the speed of the main motor of the air compressor according to the change of the used air volume under the principle of stabilizing the exhaust pressure; the air compressor can only output the required air volume while only consuming The energy necessary to output these compressed air to achieve the purpose of energy saving, the energy cost saved will far exceed the price of the air compressor itself.

Effectiveness of energy saving

The energy-saving effect of power consumption when the load of 37KW permanent magnet machine is 50%.

Features

Smooth Start
The figure shows the comparison of several starting methods. It can be seen that the variable frequency machine accelerates the start slowly, which is more stable than the soft start, and the current peak is completely avoided. After starting and running to the rated pressure, the variable frequency operation is performed, and the gas production is tracked through the stepless speed change through the pressure detection, and the gas volume required by the customer is output under the condition of keeping the pressure constant, eliminating the waste of the loading and unloading control of the fixed speed air compressor .

Constant Pressure and Power Saving
The figure shows the pressure comparison between the ordinary air compressor and the variable frequency air compressor. The ordinary air compressor has been frequently loaded and unloaded between the sufficient pressure and the pressure higher than 1.5kg, which is more stable than the variable frequency control. Under the pressure state, the 10.5% power consumption brought by the 1.5kg pressure difference is paid, (each increase of 1KG will consume 7% more power), and the zero-supply standby will consume 45% more no-load power when unloading. Therefore, the constant pressure gas supply is not only very energy-saving, but also avoids the undesirable factors caused by the short life of the unit and the unstable pressure caused by the loading and unloading control.

Effectiveness of Energy Saving
Traditional compressors (standard machines) usually use ON/OFF or proportional adjustment systems to adjust the air volume by adjusting the opening volume of the compressor's air inlet. This adjustment method can also better meet the requirements of actual gas consumption, but during the entire adjustment process, the speed of the compressor is maintained at the rated speed, and the friction work consumed by the machine and the work of stirring the coolant will not be reduced. Therefore, although the gas consumption is reduced, the actual power consumption reduction is very limited. The frequency conversion adjustment can reduce the actual power consumption of the frequency conversion compressor close to the same proportion, and the energy can be effectively used for air compression.

Reduce Energy Costs
The traditional air compressor adopts a "full load, no load" control mode and runs between two set pressure points. When the pressure is reached, the air compressor turns to no load. When the air demand is medium or low, the no-load power will be excessively consumed, which will cause a lot of waste of energy. Because it will not produce unnecessary power consumption, the energy cost reduced by permanent magnet frequency conversion can reach 35% or more. The life cycle cost (LCC) of an air compressor can be reduced by an average of 22%. All in all, compared with the fixed speed air compressor, the additional cost of the SUNWIN permanent magnet variable frequency air compressor can be recovered within 1 or 2 years.
