Because an inverter/frequency-driven compressor is not producing more air than needed. A conventional compressor works within a pressure band. When reaching the higher pressure the machine goes into unload mode (the motor is running but no air is produced).
When reaching the lower pressure again until it reaches its unload pressure again. An inverter/frequency driven compressor has less unload time and works towards a set pressure value, this makes the inverter compressors in general 30% more energy efficient than a conventional load/unload compressor.
In order to ensure that our screw compressor operates as efficiently as possible, Jinjing has independently developed its own special rotor profile. Compared with other traditional rotor profile designs, Jinjing rotor can save up to 15% energy.
Our precision machined large-size roller bearings help to make our air end have a long service life. All these, together with our state-of-the-art internal manufacturing processes and strict manufacturing tolerances, provide excellent quality synonymous with the Jinjing name.
Jinjing adopts an international advanced frequency conversion module, a special motor with speed up and down characteristics, and a set of PID parameters especially suitable for screw compressors. The control software has been tested by hundreds of thousands of compressors, with simple parameter settings and a friendly man-machine interface. The cooling of the frequency converter is specially designed. In order to support the user to set the best working pressure, the filtering area of the filter element of the oil-gas separator is increased.
