Static Mixers or Recirculation?
Static mixers provide highly efficient mixing in a single pass.  It is done quickly and with the lowest energy consumption (Pressure Drop)

The choice between static mixers and recirculation depends on the specific requirements of the mixing application.  Static mixers FAQs are well-suited for continuous mixing processes.  This is where precise blending or dispersing of fluids is essential.  They are known for their efficiency, low maintenance, and energy savings.

On the other hand, recirculation systems involve circulating the fluid back into the mixing vessel.  This helps with achieving the desired homogeneity.  This method is often used for batch processes where a more thorough mixing or agitation is required.

The decision between static mixers and recirculation should consider factors such as the nature of the fluids.  This is a required mixing intensity, space availability, and the overall efficiency and operational costs of each method.

It’s important to evaluate the specific needs of the application to determine which method would be more suitable for achieving the desired mixing results.

Cost-Benefit of Static Mixers?

Because of the efficiency of static mixers and the high mixture quality output, dosing of costly chemicals for reactions may be reduced considerably.  The cost benefit of a static mixer lies in its efficiency, low maintenance requirements, and energy savings.  Static mixers typically have minimal moving parts.  This reduces the need for maintenance and replacement, which can lead to long-term cost savings. 

They are also known for their energy efficiency, as they require less power to operate compared to some dynamic mixers.  Additionally, static mixers can often be custom designed to suit specific applications.   This can lead to improved process efficiencies and reduced materials wastage, further adding to their cost benefit. 

By providing effective mixing and blending with lower energy consumption and minimal maintenance needs.  Static mixers can offer a favorable cost benefit over the long term.  Furthermore, particularly in continuous or high-volume production processes.


Static Mixer Spacing Requirement?

The spacing requirement is minimal but depends upon the qty of elements purchased.  Vertical or horizontal installation is fine with no operational impacts.  

The spacing requirement for static mixers can vary based on several factors, including the type of static mixer, the properties of the fluids being mixed, and the desired level of mixing efficiency.  However, a common guideline for spacing static mixers is to place them at a distance.  This allows for sufficient mixing length to achieve the desired degree of fluid homogeneity.

The spacing between static mixers is often determined through practical experimentation and computational fluid dynamics (CFD) simulations to optimize the mixing performance for a specific application.  It’s essential to consider factors such as flow velocity, viscosity, and any unique characteristics of the fluids being mixed.

When designing a system using static mixers, it’s advisable to consult with a fluid mixing expert or the manufacturer of the static mixers to determine the appropriate spacing based on the specific requirements and operating conditions of the application.

Static Mixer Pipe Sizing?

Our Static Mixers are available in all standard pipe sizes, thicknesses, and lengths. 

Static mixer pipe sizing is an important consideration to ensure proper flow and mixing efficiency.  The pipe size for a static mixer is typically determined based on the flow rate of the fluids being mixed.  Also, pressure drop considerations, and the desired residence time within the mixer.

The diameter of the pipe carrying the fluids to the static mixer should be appropriately sized.  This helps ensure the required flow velocity for efficient mixing.  If the pipe diameter is too small, it can lead to increased pressure drop and reduced flow velocity.  This will help impact overall mixing performance.

It is recommended to consult with a fluid mixing expert or the manufacturer of the static mixer to determine the optimal pipe size based on the specific flow rate and mixing requirements of the application.  Additionally, considerations such as material compatibility, installation space.  Also, with system design constraints should also be taken into account.  Especially, when selecting the pipe size for a static mixer. 

What Material can Static Mixers be made of?


ProMixUSA mixers have many different materials designed for varying chemical compatibility.  Kynar, PVC, Nylon, 316LSS, Kevlar, PFA, PTFE.

Static mixers can be made of various materials to suit different applications and accommodate different types of fluids.  

Common materials for static mixers include:  

Stainless Steel:  Often used for its corrosion resistance and durability, stainless steel static mixers are suitable for a wide range of applications, including those involving harsh or corrosive fluids.

Polymer Materials:  Static mixers can be manufactured from various types of thermoplastics such as PVC, polypropylene, or PTFE (Teflon).  These materials offer chemical resistance and are often used in applications where compatibility with specific fluids is essential.

Hastelloy or Titanium:  In applications where extreme corrosion resistance is required, static mixers may be constructed from materials such as Hastelloy or titanium, which can withstand highly corrosive environments.

The choice of material for a static mixer is crucial to ensure compatibility with the fluids being mixed and to maintain the integrity and longevity of the mixer in the operating environment.  

Static Mixer Installation Requirements?


Yes, but mechanical experience is needed in order to size the piping that will connect on the inlet and outlet of the static mixers.  

The installation of static mixers involves several key considerations to ensure optimal performance and compatibility with the specific application.  Some important installation requirements for static mixers include:

Material Compatibility:  Ensure that the material construction of the static mixer is compatible with the fluids being processed to prevent chemical reactions or material degradation that could affect performance or pose safety risks.

Flow Control and Monitoring:  Consider incorporating flow control and monitoring devices to regulate the flow rate and monitor the performance of the static mixer.

Compliance with industry standards and guidelines, as well as consulting with experienced professionals or the manufacturer, can further help ensure proper installation of static mixers for optimal performance in a given application.


Do Static Mixers Require any Electrical Connection?


No external Power required on all Static Mixers as static mixers mix efficiently from the pressure drop as the fluid flow throughs the elements.  

No, static mixers do not typically require any electrical connection.  They function based on their unique design and the flow of the fluids passing through them.  Unlike dynamic mixers, which often require electrical power to operate moving components such as impellers or blades, static mixers utilize their fixed internal elements to achieve efficient mixing without the need for external power sources.  This makes static mixers well-suited for a wide range of applications where electrical connections may not be feasible or desired.

Sanitary Requirements for a Static Mixer?


The sanitary requirements for a static mixer typically depend on the specific application and industry standards. In industries such as food and beverage, pharmaceuticals, and biotechnology, sanitary static mixers are often required to meet strict hygiene and cleanliness standards.  These may include using materials that are compatible with clean-in-place (CIP) and sterilize-in-place (SIP) processes, as well as having smooth surface finishes to minimize the risk of bacterial growth and allow for thorough cleaning.  It’s important to consult industry-specific guidelines and regulations to ensure compliance with sanitary requirements for static mixers in your particular application.

The Food and Pharmaceutical industry have stringent RA and polishing requirements.  Contamination will not be tolerated so the design and build of the static mixer requires high tolerance RA readings.
