DrivE-Tech MINI

DrivE-Tech MINI


The DrivE-Tech MINI is an easy-to-use, versatile and highly featured variable frequency drive. It can be used in a wide range of pumping applications, from the residential household constant pressure control to light commercial multi-pump pressure boosting. Combined with specifically designed features, mobile app with remote control and a robust IP66, outdoor-rated, enclosure the Drive-Tech MINI improves, controls and protects surface or submersible pumping systems.
