What a variable frequency drive does
- Matches speed to demand instead of running the motor flat out
- Soft starts, reducing current peaks and mechanical shocks
- Protects the motor through current and fault monitoring
- Cuts consumption of pumps and fans: for a centrifugal pump, power varies with the cube of speed

Application example: cooling pumps
Seawater (SW) and low temperature (LT) cooling pumps are sized for worst-case conditions. Most of the time they deliver far more flow than needed. That is why we developed EnerGuard, which regulates these pumps to the real demand. Estimate the impact on your vessel with the EnerGuard calculator.
Frequently asked questions
Can a drive be installed without stopping the vessel?
Often yes. Installation can frequently be done during normal vessel operations, depending on the system.
Do you program the drives?
Yes. We handle selection, installation, programming, tuning and integration with vessel sensors and alarms.
