使用德蒙（上海）压缩机械有限公司的DMV系列变频式空压机，您不必再为复杂的电器安装和编程而操心，产品出厂前整体组装完毕，只要将主电源连接上即可立刻工作。
通过功能强大的智能控制器不断检测空气系统的压力变化，精确的改变转速，保证空压机的排气量与用户系统的需求量保持一致。智能控制器的反映速度以毫秒计算，同时对速度的修正可以在3ms内完成，使其出口空气压力带精确控制在最小以内。
成本比较 Cost comparison
德蒙（上海）压缩机械有限公司的DMV系列变频式空压机能在稳定排气压力的原则下，精确地根据使用气量的变化改变空压机主电机的转速，使空压机只输出所需要的气量，同时也只消耗出这些压缩空气所必须的能量。从而达到了节约能源的目的，在整个机组运行周期中所节约的能源费用将远远超过空压机本身的价格。
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.
启动和运行 Start-up and operation
图中显示的是几种启动方式的比较，可以看出变频机是缓慢地加速启动，比软启动更加平稳，完全避免了电流峰值，在启动运行至额定压力后变频运行。能最大程度上适应电力不足的使用环境。
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 absolutelyavoid the current peak. After running to the rated pressure, it will operate with variable frequency,which can adapt to the power lacking environment.
