Kenics KM Static Mixers

Principles of Operation

In all Kenics® KM Series Static Mixers, a patented helical mixing element directs the flow of material radially toward the pipe walls and back to the center.

Additional velocity reversal and flow division results from combining alternating right- and left-hand elements, thus increasing mixing efficiency.

All material is continuously and completely mixed, eliminating radial gradients in temperature, velocity and material composition.

Numerous independent studies have shown that Kenics Static Mixers maximize mixing efficiency without the wasted energy and material blockage typically found in more restrictive motionless mixers.

The KMX static mixer is the best choice for demanding mixing applications, such a those involving fluids with extreme viscosity or volume ratios.

Principles of Operation

The KMX utilizes cross-stream mixing and flow splitting to achieve very rapid blending. Each element is approximately one pipe diameter in length and consists of multiple intersecting blades, which generate fluid layers as the mixture flows downstream. Each blade features concave construction offering better cross-stream flow than flat blades for superior mixing per unit length in tough, high viscosity ratio applications. Sheets of low viscosity additives are driven along the trough of each blade and abruptly sheared by strong cross-stream velocity gradients as they pass around the upstream surface.

Kenics HEV Static Mixer

HEV Static Mixer features include:

Lowest pressure drop available
Unlimited sizes and shapes
Shortest possible mixer length
Easy retrofit to existing lines
Available in all metals and alloys, FRP, PVC, PFA, and epoxy-coated steel

HEV high-efficiency static mixers handle all turbulent-flow mixing applications regardless of line size or shape. Mixing is accomplished by controlled vortex structures generated by the patented low-profile tab geometry. This provides uniform blending while limiting mixer length to less than 1-1/2 pipe diameters. Complete mixing is achieved with pressure losses 75% less than conventional static mixers. Typical applications for the HEV include all low-viscosity liquid-liquid blending processes, as well as gas-gas mixing. The HEV is ideal for processes where pressure loss and length are critical.

Kenics WMV Static Mixer

Chemineer has designed and manufactured static mixers under the Kenics trade name for the water and wastewater industry for over 30 years. The first applications used the Kenics helical element KMS mixer, and this is still used widely today for pipes of 150mm diameter and less, for gas-liquid dispersion applications and where mixing is required at very low flow conditions.

In the early 1990's Chemineer researched, patented and introduced a novel and unique type of static mixer that generated multiple vortexes to create highly energy efficient (low head loss) radial mixing effects. This mixer, which we called the HEVTM (High Efficiency Vortex) set the standard for ultra low head loss mixing. Over the last 12 years over 1000 full scale HEV mixers with diameters ranging from 50 to 2200mm and for open channels up to 6m wide have been installed worldwide in water and waste water plants.

Kenics Heat Exchangers

Kenics^® Static Mixer technology, available exclusively in Kenics^® Heat Exchangers, offers the highest available coefficients for fast, uniform heat transfer. Capable of reliable operation in a wide range of process applications, including those in the polymer, plastic, and food and beverage industries, Kenics Heat Exchangers require less space, less energy and less residence time than standard designs.

Static Mixing Element Technology

The Kenics Heat Exchanger consists of a continuous string of static mixer elements within each heat exchanger tube. Fluid flow is directed radially toward the pipe walls and back to the element, regardless of velocity. Additionally, momentum reversal and flow division also contributes to the mixing efficiency. All processed material is continuously and completely intermixed to eliminate radial gradients in temperature, velocity and material composition. As a result, Kenics Heat Exchangers provide predictable, controlled mixing, and the most efficient form of thermal transfer available today.
