Product Description

The Kestrel Static Mixer, also known as a motionless mixer, utilizes a series of repeating simple metal components configured in a standard pipe or tube for the continual mixing of fluids. Process line flow produces energy requiring no motors, gears, belt drive, or energy costs.

Static mixers and stirred tanks contrast in that a static mixer achieves an order of magnitude higher energy dissipation rate in a uniform volume. Competitive fast reactions where limited mixing rates and product purity critical find this extremely important. The high energy dissipation rates achievable will improve multiphase mass transfer or produce fine emulsions dependent on the application.

The static mixer divides the process stream and then re-divides it with a series of elements set at right angles to each other. Special cavities in the mixer randomize the distribution of fluids by direct stream impingement. This enhances and optimizes the two-by-two division process making it truly effective.

When static mixing occurs under turbulent flow, both sides of each element produce elliptical vortices rotating in opposite directions – eliminating streaming or tunneling effects. Back-mixing occurs as fluids are orbited in the vortex from the front to the back of the previous element.

Static mixers produce substantial improvement in mixing efficiency – requiring fewer elements and resulting in a lower pressure drop for given mixing processes.

The application determines that material used to build the static mixer in addition to the number of elements used.

Philadelphia Mixing Solutions Limited has more than 100 years of experience developing customised mixing systems for industrial use. Our series of static mixers offer a low-cost, easy-to-install solution that can be configured to deliver reliable results in any situation. Backed by Philadelphia Mixing Solutions’ unbeatable reputation for quality and customer support, these static mixers can be optimised for mixing, blending, liquid dispersion, emulsion formation, laminar flow, heat transfer and many other potential applications.

Technical Background

Our static inline mixers work by splitting and diverting input streams through a series of elements installed in a pipe. These elements direct each liquid towards the pipe walls, providing velocity reversals and flow diversion, which in turn increase the efficiency of the mix. Different diameters and different element configurations alter the degree of mixing being provided. Static mixers can be used for both high- and low-viscosity fluids, as well as for turbulent blending, laminar blending and liquid dispersion applications.

Static Mixer Benefits

Our static inline mixers offer a number of advantages, including:

  • Easy installation into any existing tubing system
  • High-quality results with a low operating cost
  • Self-cleaning, maintenance-free design
  • No moving or electronic parts
  • Suitable for use in explosive environments

Whether you need to blend two or more liquids into a homogeneous mixture, inject a metred liquid into a process stream or perform any other mixing or homogenisation task, a KestrelÔ static inline mixer can be configured and optimised to your specific needs.

A Valued Partner to the Energy Industry

Philadelphia Mixing Solutions’ static mixers are often used in oil and gas pipeline applications. We understand the need operators in these industries have for reliable, low-maintenance products, and we have designed all of our inline mixers to meet the high standards set out by the American Petroleum Industry (API) and Process Industry Practices (PIP) organisations.
