WEG supplies W22 motors to mining desalination plant

03 March 2023

Motors for use in desalination plants are required to operate in severe climates 24/7. They are highly durable, with a special coating to protect against seawater corrosion and high efficiency to minimise energy consumption.

As part of WEG's work in the mining water segment, the company has supplied its motors to an important complementary infrastructure project in the north of Chile.

To guarantee that the water reaches the different supply points, WEG has delivered W22 motors with IE3 efficiency that are used in the water feeding and recirculation processes of the desalination plant. Vertical application motors were also supplied for the plant's capture system.

WEG’s W22 range of three-phase induction motors is designed to offer not only significantly lower energy consumption, but lower noise and vibration, higher reliability, easier maintenance and lower cost of ownership. 

The W22 motors reduce energy consumption, offer excellent cost-effectiveness, and consequently greater productivity and lower costs for the industry.

The motors are built for the most severe operating conditions, such as operation in marine and saline environments, their mechanical design not only optimises characteristics such as weight and length, but also adds durability and easy maintenance to the product in remote regions.

The IE3 efficiency level guarantees reduced energy consumption and increased productivity, offering an excellent cost-benefit ratio. All the motors were manufactured with a special epoxy painting plan for performance in severe marine environments with a high salt index.

For WEG, such a project represents an important reference in the mining water segment with quality and efficiency solutions, providing the customer with reliability and great energy savings.

WEG products allow your plant to be a flexible, safe and reliable installation with operating stability and the highest production levels.  For further information about WEG’s W22 motor range for severe operating environments, visit
