The homogeneous mixture of crystals in the crystallizer is circulated by an external pump.

Minimum investment

Due to its simple design, the investment and working costs are greatly reduced. Small compared to other technologies, this crystallizer is easy to implement and reduces the costs of huge projects.

Simplicity of transaction

Simple and robust design, this crystallizer allows an easy conduct to the detriment of the quality of the crystals.

Crystal size

The substantial contact between the crystals and the pump limits the growth of the former.

The residence time is limited to a few hours because the effects of crystal attrition become so prominent in growth rate.


This type of crystallizer is very suitable for production without grain size constraints.

Used in many industries, forced circulation is also used in the ZLD (Zero Liquid discharge) units.
