Inline Dynamic Mixer

Napier-Reid Inline Dynamic mixing system ensures any chemicals added to the process pipeline are completely and uniformly dispersed throughout the flow stream. It is excellent for flocculant dispersion, pH control, polishing, and other dispersions of chemical additives.

Vessel internals promote optimum flow patterns to ensure quick and complete dispersion of additives and prevent short circuiting

Inline Static Mixer

Inline Static Mixer

Napier-Reid’s Inline Static Mixer (ISM) is a static device for mixing (blending) two or more liquid materials. It does not consist of any moving parts. The fluids are stirred and mixed as they flow through the mixer.

The ISM consists of specially designed mixing elements, that are installed inside a cylindrical housing. As the fluids flow through the mixing elements, the elements cause turbulence. They rotate the fluid radially towards the wall of the housing or rotate it back towards the centre.

Also, the mixing elements change the direction of rotation of the fluid from right to left, or left to right. Due to the sudden change in direction of flow, turbulence is created.

Napier-Reid manufactures a variety of mixing elements to meet different process requirements. However, the mixing principle of all elements is to generate turbulence energy by flow division, flow reversal, and radial mixing, and to convert the turbulence energy into efficient mixing.

 

For proper selection of Napier Reid’s inline or top entry mixers, various factors are taken into consideration: flow rate, viscosity, characteristic of the fluid flowing through the mixer and fluid to be mixed, housing length, housing inner diameter, available hand, allowable pressure drop, type of element, and number of elements.
