Counter-Swirl Series 6000 static mixers

The Counter-Swirl Series 6000 static mixer from H2O Rx is a ‘spool’ type mixer, bridging the 2850 Series and 3050 Series, while providing additional benefits. The mixer offers engineers a solution for their mixing problems, with three curved fins welded to a pipe interior. The two side fins are welded upstream of the centre fin, with the third fin welded downstream of the injection port. Developed by Westfall Manufacturing and Alden Laboratories engineers, Model 6000 features a headloss co-efficient of 1.26 and a mixing COV of 0.025, which makes it better than 1 and 2 state 3050s, and 0.9 Beta 2850s. The Series 6000 sits between the two existing ranges.

The mixer is compact, reducing space requirements before samples, offtakes and branches. Up to three injection ports can be provided, all in the same line as the main process pipe, and on one side only. This simplifies the arrangements for dosing lines, access and maintenance, particularly when more than one dosing point is required. The mixer is designed with one to three injection nozzles and can fit in tight spaces where short lay lengths are required. The mixer is designed to reduce pressure loss to a K factor of 1.26, with incoming fluids or gases entering the high-shear zone of turbulence after the additive is introduced.

The mixer can be custom designed and made to suit different applications. It resists fouling, requires minimal maintenance and is easy to install. The mixer has a size range from DN20 to DN3000 and is available in most common pipe materials. Depending on the application, it can be 3D printed, with injection ports built in. The Model 6000 is CFD designed and tested, with no external energy requirements and no moving parts.
