ECOTEAM produces purification units [ECOFR-S], whose aim is the removal of Iron Sulphate by crystallization.
The crystallization of the Iron Sulphate is induced by the solution's cooling, due to the strong dependence of the solubility on the temperature.
The ECOFR-S system, thanks to a refrigerator circuit, allows the cooling of the solution within a chamber of crystallization, which prevents the scaling of the heat exchange surface, through a scraping system.
The removal of Iron Sulphate allows the purification of acid pickling
