• The client’s objective was to automate the dosing process of liquids in the evaporator units

  • Reduce the time operators spent manually weighing the liquids and pouring the liquids into the evaporators, using jerry cans and buckets.

  • Reduction of product spillage.


  • Saen Engineering was selected to provide the electrical and mechanical engineering for this project.

  • The required components, such as load cells, valves and pumps, were selected by Saen Engineering.

  • Saen Engineering designed a system with three pumps, three scales and fifteen valves. The system will dose the desired amount of oil or sodium hydroxide to the evaporator.

  • We provided the electrical and mechanical installation of all components.


  • Dosing of the liquids at the push of a button.

  • Reduction of operator actions.

  • 5% increase in output per evaporator.

  • No more spilling of product.

  • Increase in plant safety as NaOH is now dosed in a closed system.

About the project

The process of dispensing in the factory in question was not fully efficient; all liquid raw materials were measured out using jerry cans and dosed into the vessels. Now it’s possible to dispense the liquid raw materials with just the push of a button.
