Mixing & Heat Transfer Studies

Customized studies to determine process optimization and efficiency


Agitation and mixing are major process components in the chemical and pharmaceutical industries. But we can no longer speak of empirical methods. The accumulation of industrial data and a significant research effort currently favor a scientific approach to agitation techniques.

De Dietrich bases its expertise on tests conducted on small-scale models, digital simulations and sustained collaboration with specialist laboratories. 

De Dietrich has confirmed its position as a primary partner in the design, definition and calculation of agitation.


Knowing the importance of thermal transfer in the success of a process, we have constantly developed our expertise to optimize the thermal operation of our reactors.

In order to meet the needs of its customers, De Dietrich has developed proprietary thermal transfer calculation software and has acquired specific work equipment that enables it to produce the coil reactors that have become essential to a large number of processes.

Today, De Dietrich is capable of adapting to the processes and utilities of its customers.


To improve process efficiency, De Dietrich proposes a new experimental, digital approach.

The programs employed are various: pilot test stations with data acquisition in real time, study of flows generated by an agitator, establishment of the critical emulsion speed.

Digital simulation also finds an outlet in various applications: speed profile analysis around moving parts, primary run-off flows, turbulence studies, calculation of thermal data.
