Designed for wastewater treatment applications, such as activated sludge treatment, sludge holding tanks and digesters, as well as for biogas applications, ice prevention and oxygenization of lakes and harbours, Flygt 4320 mixers can be easily adapted to meet changing process and load conditions. Combining a high efficiency mixer with a unique, integrated variable frequency drive (VFD), the Flygt 4320 makes it possible to minimize life cycle costs and mixing energy costs.
Andreas Lindberg, Product Manager for Mixers at Xylem, said, “Our research and development team has succeeded in developing a mixer that offers optimum efficiency and simplicity of operation. A key reason for this is the mixer’s adjustability – once installed at a facility the mixer thrust or speed can be altered to cater to that facility’s specific conditions; this can dramatically reduce energy consumption. It also future-proofs a facility’s mixing efficiency as the motor speed can be altered when the mixing demand increases or decreases. Every component is engineered in-house – from propellers and shaft seals, to motors and gearboxes – so customers can be assured of Flygt quality and reliability.”
Flygt 4320 mixers are prepared with remote communications for compatibility with central control systems. It is also equipped with soft start and soft stop features which regulate the motor revolutions, increasing stability of the mixing system and reducing electric inrush currents.
