WEG’s CFW11W Offers Higher Power

WEG presented its CFW11W variable speed drive to the shipbuilding and marine industry for the first time recently, and according to WEG, the water-cooled drive offers up to 40% higher power in a more compact size than standard air-cooled inverters and as a result enables shipbuilders to increase efficiencies and optimize their processes on board. The modular, water-cooled CFW11W frequency inverter from WEG offers a solution to space and corrosion challenges.
With power ratings from 450 kW to 2,800 kW, CFW11W is suitable for low-voltage applications and is suited for critical and support drive systems such as rudder systems, bow and stern thrusters, winches, pumps and fans. As the inverter is water-cooled, there is no additional need for fans and it offers significant size savings compared to air-cooled models. CFW11W is an economic solution, eliminating the need for costly air-conditioned electrical equipment rooms.
Aside from water cooling, the CFW11W inverters are structurally identical to WEG’s standard CFW11M models in the same product family.
