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. )
Cost comparison:
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. Start-up and operation:
From several start-up modes shown in the chart, we can see that the variable frequency
compressor start-up style is of slow to add speed, which more stable than soft start and absolutely
avoid the current peak. After running to the rated pressure, it will operate with variable frequency,
which can adapt to the power lacking environment. Constant pressure for air supply with balance:
In the chart, it shows the operating condition between normal air compressor and variable frequency
air compressor. According to the various of air requires to adjust the speed of motor to make sure
the air output and air requires are balanced, so avoid machine to frequently load and unload during
various of air requires, which compared with the traditional compressor, the variable frequency air
compressor could save about 35% of energy or more. Stable pressure output can control the pressure
between 0.01MPa-0.02MPa, which avoids the high load current lost because of the traditional
compressors' 0.05-0.2MPa pressure.
