robicon w drives for water & wastewater

Robicon W-Series drives for municipal water & wastewater applications

For more than a quarter century W-Series variable frequency drives, built on Robicon field-proven expertise, have reliably served the drive needs of U.S. municipal water and wastewater utilities - representing the largest installed base among all drives currently in service within the industry . And with the integration of SINAMICS technology and features backed by Siemens' total solution and system capabilities, the best has become even better.

Clean power drives include an 18-pulse rectifier front end combined with a patented phase-shifting autotransformer.

IEEE sets minimum harmonic distortion limits for voltage and current. With the W Series Clean Power unit's multi-pulse, phase-shifting design, the Clean Power models more than meet distortion limits for the 5th, 7th, 11th and 13th harmonics in accordance with Table 10.3 of IEEE 519-1992

Available seismic certification for use in essential facilities

Benefits of Clean Power Drives

  • No line side harmonic disturbances

  • Elimination of external power factor correction devices and their associated costs

  • Avoidance of utility penalties for poor power factor

  • Improved voltage regulation

  • Avoidance of overloading feeders, breakers and transformers with reactive power

  • Compatible with operation on generator supplies and weak power systems. Unlike harmonic filters, Clean Power 18-pulse drives do not present capacitive loads that cause voltage increases at low loads, a frequent cause of problems on weak or emergency supplies

  • Low loss operation especially at partial loads. Alternative technologies that use front ends with active switching devices (IGBTs) have high switching losses at all loads - unavoidable when regenerative operation is required but not desirable on pump and fan drives whose main purpose is energy savings
