德耐尔微油螺杆式压缩机：两级压缩工频-机组会自动调节DA+

在设定的变频压力下，机组会自动调节，使输出压力始终保持在士0.1bar以内,减少不必要的浪费。压力每上升1bar,耗电量上升7%)。
Under the set frequency conversion pressure, the unit will automatically adjust to keep the output pressure within 土 0.lbar, reducing unnecessary waste.(The power consumption increases by 7%6 every time the pressure increases by l bar). 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,启动更加平稳,完全避免了电流峰值.
The figure shows the comparison of several startup modes. lt can be seen that the inverter starts slowly, accelerates, starts more smoothly,and completely avoids the peak current.
