Optidrive variable frequency drives, 0.5 to 400 HP
Drives are where energy saving becomes real: throttle a pump with a valve and you pay for the pressure drop forever. We size, supply and commission Optidrive units across the Ankleshwar belt.
The Optidrive range
Five families, each tuned to a duty. Choosing the right one matters more than shaving a few percent off the price — a general purpose drive on a hard constant-torque load will trip, and a high performance drive on a fan is money spent for nothing.
Send the motor nameplate
Full load current, kW, voltage and duty. Add the load type — pump, fan, mixer, hoist — and we will confirm the frame, the rating and whether you need a line reactor or brake resistor.
Pick a drive by duty
| Application | Load type | Recommended |
|---|---|---|
| Centrifugal pump, cooling tower fan | Variable torque | Optidrive Eco |
| Conveyor, blower, small machine | Light constant torque | Optidrive E3 |
| Agitator, extruder, crusher, hoist | Heavy constant torque | Optidrive P2 |
| Refrigeration compressor | Compressor duty | Optidrive Coolvert |
| ETP pump, washdown area, outdoor | Any, harsh environment | IP66 switched drive |
VFD FAQs
How do I select the right rating?+
Size on motor full load current, not kW alone, then check the load type. Variable torque loads take a standard duty rating; heavy constant torque loads need heavy duty rating and often one frame larger. Starting torque, cycle rate and ambient temperature all shift the answer.
Can a drive sit in a wet or dusty area?+
Yes. IP66 units with integral disconnect are designed for washdown and outdoor mounting, which removes the cost of an air-conditioned drive room in food, chemical and effluent plants.
Do you help with commissioning?+
Yes — parameter setting, motor auto-tune, PI loop configuration and fault diagnosis, plus warranty coordination with Invertek as their authorised channel partner.
Will drives upset my power factor?+
Drives draw non-linear current, so harmonic distortion rises even when displacement PF looks healthy. In a plant with many drives, capacitor banks must be detuned — see power factor correction — and where THD is high, line reactors or filters are worth costing in.
