H2O Rx custom build a range of static mixers - wafer-style, variable flow, low headloss, and open channel mixers - in many materials and sizes to suit fluid applications in most industries.

K Value (kV) for headloss coefficient, Coefficient of Variation (CoV) for amount of mixing, Computational Fluid Dynamics (CFD) reports, white papers, and material certificates are available for all H2O Rx's static mixers to ensure that you are confident in each mixer for your application.

H2O Rx is the exclusive Australian licensee and distributor of the Westfall Manufacturing range of static mixers manufactured in both Australia and USA.

Types of Static Mixers

There are seven varieties of static mixer in the range. These are:

Series Description Diagram
Series 2800

Series 2800 Wafer-Style Static Mixer - standard mixer that slots between two flanges for space saving mixing and low material costs. Excellent mixing, completes within 10 pipe diameters.

0.8 Beta 13.63 0.009
0.9 Beta 6.78 0.05

 

2800 Series
Series 2850

Series 2850 Flanged Wafer-Style Static Mixer - special purpose or retrofit replacement. A full body or "double flanged" variant that can be multistage if the application requires. Excellent mixing, completes within 10 pipe diameters.

2850 Series
Series 2900

Series 2900 Variable Flow Static Mixer - for extreme ranges of flow. For mixing when the process flow rate varies significantly. Excellent mixing, completes within 10 pipe diameters.

2900 Series
Series 3050

Series 3050 Low Headloss Mixer - specifically designed for installations where only very low pressure drop is permissable but mixing is important. Excellent mixing, completes within 10 pipe diameters.

3050 Series
Series 4000

Series 4000 Open Channel Mixer - a low headloss mixer specifically designed for open channels which allows for a flatter hydraulic grade line to maximise mixing without high pressure..

Mounted in a penstock for removal for easy cleaning..

4000 Series
Series 5000

Series 5000 Open Channel Mixer - a low headloss mixer where the fins are bolted directly into the floor of an open channel.

Designed for open channels which allows for a flatter hydraulic grade line to maximise mixing without high pressure.

5000 Series
Series 6000

Series 6000 Counter Swirl Rapid Mixer bridges the gap between the 2850 Series and 3050 Series mixers with excellent mixing, low headloss and as an additional benefit, mixing in a very short distance - 3 pipe diameters.
