sinamics g120x for pumps, fans, compressors

SINAMICS G120X Infrastructure drive for pump, fan and compressor applications

We don't have to tell you that on any given day there's more water and air moved than anything else. And it sure seems simple: turn on the pump and move the water / turn on the fan and move the air. How on earth could anyone improve on that? Siemens did. In developing the world's leading equipment control for industrial solutions, Siemens continues to explore and develop new ways of making even the most basic processes more efficient and cost-effective. From the immensely successful SINAMICS G120 family of drives, the G120X is an “infrastructure” drive targeted for pump, fan & compressor applications in the Water & Wastewater (W&WW), HVAC, irrigation/agriculture & industrial chiller/refrigeration segments.

  • Estimate the running data without sensors
    G120X can estimate the energy savings from the flow characteristic obtained from a pump manufacturer

ECO mode

  • Advanced energy saving / motor control technology
    Realized by slightly changing the output voltage (via excitation current) to find minimum input power. This provides energy savings for applications without knowledge of the characteristic curve

Deragging mode

  • Cleans blockage from impellers and protects the pump
    Used to clean any clogs / obstructions on the pump impeller, pipes or valves. Consists of running the motor forward and reverse to clean the impeller. Mode can be enabled after power-up, for every run or with an input signal
