Precision speed regulation, soft starting, and maximum energy efficiency for AC electric motors
Nairobi Power Engineers manufactures turnkey enclosed Variable Frequency Drive (VFD) control panels for water pumping, HVAC air handling, industrial mixing, and process machinery. By matching motor speed to instantaneous process demand, our VFD panels cut electrical energy consumption by up to 50% on centrifugal loads.
We incorporate top-tier drives including Lovato Electric VLB3 / VLA1 series and ABB ACS580 / ACS880 platforms into custom IP54 ventilated enclosures complete with line reactors, EMC filters, emergency bypass contactors, and multi-pump cascade controllers.
Lovato VLB3 Series • Compact VFD
Versatile three-phase variable speed drives featuring sensorless vector control, built-in Modbus RTU, STO Safe Torque Off, and compact footprint.
Enclosed Solutions • Multi-Pump
Custom engineered duplex and triplex water booster panels with pressure transducer PID control, automatic lead-lag cycling, and soft pipe filling.
