The Operational Advantages of the FLEXIMIX Additive Injection System by ISOIL

The FLEXIMIX injection system by ISOIL has been developed with a clear objective in mind: to engineer a cutting-edge solution for precise additive injection management.


FLEXIMIX e has been designed to precisely introduce up to six different additives per loading arm into the primary product stream. In this way, the quality and performance of the whole operation are maintained, guaranteeing excellent results across several applications - even during tank truck loading operations.


Furthermore, the FLEXIMIX additive injection system precisely proportions each additive to introduce just the right amount of substance needed and, thereby, reducing waste. It also features an advanced and sophisticated "washing" function that clears lines of any residual additives before final product delivery, preventing cross-contamination.

The Working Principle Behind the FLEXIMIX Additive Injection System 

The strength of the ISOIL solution is its adaptability. In fact, FLEXIMIX is the ideal choice for fuel additive injection systems, as well as for any other application requiring exact dosage.


At the heart of the FLEXIMIX, there is the Injection Controller Main Unit (IC-M), a microprocessor-based controller with a specialized software for accurate additive injection according to specific recipes. The IC-M continuously measures the main product’s flow while controlling solenoid valves on the Injection Blocks (IB2) to begin the process. The flow additives are meticulously measured by a high-precision P.D. meter within the IB2, ensuring that the additive-to-product ratio is maintained throughout the operation, regardless of the fluctuations in the main flow.  


Each IB2 block encompasses a precision oval gear flow meter and a solenoid valve that work in tandem to dispense the additives. The system’s modular design allows the adjustment of the injection scale from very low to higher flows, depending upon the different requirements of the applications. 


The FLEXIMIX additive injection system includes advanced features, such as: 


  • remote control operation;
  • automatic calibration;
  • flushing function for post-operation cleaning.
