The Vaughan Rotamix® system takes hydraulic mixing for sludge tanks, digesters and other high-volume applications to the next level.

The Rotamix dual-zone mixing pattern is a combination of both uniform and vortical fields of flow. With dual-zone mixing, average velocities are higher and steadier. Solids are also prevented from settling in the center. High velocity nozzles also increase the effective mixing volume by inducing entrained fluid, thus significantly increasing the overall mixing effect.

What makes the difference with the Vaughan Rotamix system is the use of fixed nozzle assemblies. Once the nozzle assembly is installed, the nozzles are adjusted to the factory specified angle, and permanently tightened. No additional adjustment is required.
