Static Mixers
Static mixers are well known in the process industry for mixing, blending and related tasks. It is a device which has a series of fixed, geometric elements enclosed within a tubular cylindrical or square housing. The fluids to be mixed are fed at one end of the housing. The internal elements impart flow division and the fluids are directed both outward and inward due to the geometry of the elements. Thus radial mixing of the fluids occur while flowing forward to the other end to produce uniformly mixed desired product. Simultaneous heating or cooling can be done by imparting a jacket outside.
Both elements consisting of a series of baffles and housing are made from metal or a polymer. Stainless steel and other exotic metals, polypropylene, PTFE (Teflon) etc. are used.
In static mixer, materials flowing are mixed solely by redirecting fluid flow to follow the geometry. The only power required for static mixers is the external pumping power that propels the material through the mixer. Static mixers employ the principle of dividing the flow and recombining it in a geometric sequence. It is also called a "Motionless Mixer"
The overall system design is dependent on many variables including the physical properties of fluids, mixer length, tube inner diameter, the number of elements and their geometrical design.
Fenix Static Mixer
Fenix® offers static mixers in wide ranging capacities for various applications, flow properties and varying pressure drops. We manufacture them in SS and other exotic metals and alloys, and PTFE-lined material.

Control of reaction with narrow residence time distribution Selection of Fenix Static Mixer : The pressure drop is probably the most important design parameter for static mixers, because it is responsible not only for the size (and cost) of the equipment but also the energy consumption of the feed pumps for the fluids to be mixed. And the volumetric flow ratio of the fluids determines the size in terms of Number of Elements for the FenixTM Static Mixer. FMV
