WEG Motor and Inverter Equipped Plant Honored and Recognized by Guinness World Records as “Largest Reverse Osmosis Desalination Installation in the World”.
International water markets increasingly require structure and innovation to meet global needs. WEG informed on April 26 that the largest seawater desalination plant in the world, Rabigh 3, was inaugurated on March 31 in Saudi Arabia, in which the Brazilian multinational participated as a supplier of motors and frequency inverters.
The success of the project was honored and recognized by Guinness World Records as the “largest reverse osmosis desalination installation in the world.”

Brazilian Multinational Leader in Turbine Manufacturing Equipped the Largest Desalination Plant on the Planet with 69 Electric Motors and 50 Frequency Inverters
In total, there are 69 electric motors and 50 medium voltage frequency inverters supplied through industry companies, such as the consortium Abengoa, SIDEM, and Sepco III, which is responsible for the engineering, supply, construction, and commissioning of the plant.
Rabigh 3 was built on the western coast of the Red Sea and has the capacity to produce 600,000 m³ of water per day and supply approximately three million people. It is also characterized as the most eco-friendly plant in the world due to its lower electricity consumption during daily operations and has recorded the lowest noise level.
“This WEG investment, based on exclusively serving large engineering companies, has guaranteed the company new supplies in the Middle East and also experience to meet the national demand, which is increasingly intense due to the new regulatory framework for basic sanitation, enacted in Brazil,” stated the Brazilian company.
