ZTMX SRA-Series Static Mixers

High viscosity and low flowrate can create a change in flow regime from turbulent to laminar. In traditional bladed static mixers such as the ZelenTech ZTMX this reduces the mixing efficiency and it may not be possible to reach a mixing degree of ≤0.05 CoV, or it may be posible only using a large number of elements. Large number of elements becomes both costly and impractical. The ZelenTech SRA Static Mixer comes to the rescue. The ZelenTech SRA Static Mixer produces very low CoV values in a short distance through a combination of Subdividing, Relocating and Agitating (SRA).

ZelenTech SRA Static Mixers consists of an array of flow diverters located after each other in such a way that they form an agitating chamber in between each. The stream is cut into 5 substreams by each element and releases these streams at oblique angles in the carefully designed mixing chamber between each element. As an example, a 4 inch SRA mixer will create 1250 subdivisions in less than 1 meter, with turbulent mixing occuring at each stage.

Correctly applied, this design produces a large amount of mixing and extremely small droplet sizes no matter how different the streams to mix are in way of density/viscosity.

Our static mixers are available as fully flanged spool sections or as insert mixer blades to be welded into client pipes. We have made mixers as small as 3/4 inch up to 48 inch in many configurations. We have the capability to make spool sections for low as well as high pressures in a variety of materials.

Our production facility is fully qualified for welding procedures and we can provide anything and everything found in your piping specification. Welding certifications, NDT, customized paint job or whatever it may be.

The ZTMX SRA Mixer can be fitted with injection ports or sampling ports as needed. Sampling Ports will be located in compliance with API8.2 and ISO 3171 to achieve representative samples.

For accurate water content reading we can also incorporate the ZTMX mixer into our ZT-100 Watercut Meter, either as an integral part as for our S ad F-Series, or as a separate spool section suitable for the new I-Series insertion meters.

With the ZelenTech ZTMX you will have no mixed feelings.


"A static mixer is a device for the continuous mixing of fluid materials. Normally the fluids to be mixed are liquid, but static mixers can also be used to mix gas streams, disperse gas into liquid or blend immiscible liquids. The energy needed for mixing comes from a loss in pressure as fluids flow through the static mixer. One design of static mixer is the plate-type mixer and the other device consists of mixer elements contained in a cylindrical (tube) or squared housing. Mixer size can vary from about 6 mm to many meters in diameter. Typical construction materials for static mixer components included stainless steel, polypropylene, Teflon, PVDF, PVC, CPVC and polyacetal."
