Static mixers can be applied to a wide range of process operations, including dosing, dispersion, laminar flow heat exchange and emulsion formation. They offer many key benefits for combining liquids, gases and powders and they are tried, tested and trusted in many different industries. Mixing action is achieved by the continuous splitting, extension and transportation of the components. Motionless mixers use a series of precisely configured mixing elements to process the components. Differences in concentration, temperature and velocity are equalized over the flow cross-section. 

For further information go to principles of operation. Mixers are supplied as simple plain ended pipe sections, flanged with multiple injectors and sampling points, fitted in bends, or in square or rectangular section for ducts and open channels. They are manufactured in a wide range of materials, including carbon steel, stainless steel, exotic alloys, GRP, uPVC, cPVC, PTFE, etc.

The elements are made in various designs to suit different applications, and are available fitted into a range of housings, from high pressure to open-channel, making them ideal for all kind of industrial environments. The elements are fixed or removable and the necessary number of mixing elements for a specific application depends on the required homogeneity and on the volume flow ratio of the components.  

Mixer elements

The homogeneity requirement differs according to the particular mixing task and should specified by the final user in terms of variation coefficient CoV. Usually a CoV between 0.01 and 0.05 is a reasonable target for most applications. The lower the value of CoV the better the mixture quail

Benefits

• Static mixers deliver a high level of mixing efficiency, therefore the consumption of dosed chemicals and formation of byproducts can be dramatically reduced. 
• They eliminate the need for tanks, agitators, moving parts and direct motive power and they allows to gain highly efficient mixing with low energy consumption. 
• The energy required for mixing is efficiently extracted as pressure drop from the fluid flow through the elements. Mixers are invariably installed in existing systems without reducing the capacity of existing pumps. 
• The installation is very easy, no special skills are required other than normal engineering skills. 
• Mixers have no moving parts and are virtually maintenance free. 
• Static Mixers are available in all standard pipe sizes and, in the case of open channel designs, are available in any size with no upper limit. 
• Each Static Mixer is carefully designed to meet the specific requirements of each application

Application

Static mixers are installed in thousand of process plants worldwide, providing the highest standard of mixing efficiency, reliability and economy.

There are two types of Static mixers, Channel mixers: installed in new treatment works or retrofitted in existing installations, they rapidly achieve a high degree of mix with extremely low headloss on very short lengths. Channel mixers cover a wide range of flow rates and are ideal for efficient chemical dosing. They allow chemical savings with consequently economical and environmental savings. Pipe Mixers: in stainless steel, PVC, PP, carbon steel, fixable or removable. Available with heating and cooling jackets, injectors, sample points and instrumentation bosses. Suitable for all industries. Wide range of diameters: from 10 to 300 cm.
