variable frequency screw air compressor

  • variable frequency screw air compressor1
  • variable frequency screw air compressor2

DREAM DMV screw air compressor can, under the principle of stable discharge pressure, change the rotation speed of the main motor precisely according to the variety of using air capacity, to make the air compressor just discharge the needed air capacity, meanwhile, it also just consumes the energy needed for discharging the compressed air. Therefore, it has achieved the goal of energy- saving, which means the saved energy expense during the operating period of the whole machine far surpass the price of air compressor itself.

【Brand】: Dream

【Type】: DM-V

【Power】: 18.5~315 KW

【Air delivery】: 1.1~59.8 M3/min

【Working pressure】: 0.75~1.30 Mpa

Features



▲Strict Requirement for best energy saving;

▲Starting & Running the impact of the grid is small,after the starting to run and reach the rated pressure and the compressor will operate in the variable frequency mode;

▲Constant pressure air supply to keep the balance between air supplying & air 

Consumption;

▲Excellent controlling system leads to safety protection function.
