The considerable daily load variation in water or wastewater treatment plants makes it economically feasible to introduce motor control on rotating equipment such as pumps and blowers. Featuring a wide range of powerful standard features, which can be expanded with performance-improving options, the drive is equally suited to both new and retrofit projects. The VLT® AQUA Drive is designed to provide the highest level of performance of AC-motor-driven water and wastewater applications. Maximum energy efficiency for water and wastewater applications
