VarioGen lowers CAPEX by reducing the size of the generator required.
Combined with significant OPEX savings owing to lower maintenance and operation costs (fuel) by running the pump at lower speeds
and you have the most cost-effective Generator Control Solution available today.

Note:
Note 1 DOL Direct On Line (DOL) generator selection is based on 5 times of the electrical motor startup inrush current
Note 2 Soft Starter (SS) generator selection is based on 2 times of the electrical motor startup inrush current
Note 3 Variable Speed Drive (VSD) generator selection is based on 1.8 times of the electrical motor startup inrush current
Note 4 Wide frequency range may not be allowed by the pump manufacturer
Note 5 System running to a fixed frequency
Note 6 System running within a defined variable frequency range
