Features
Designed to demonstrate process of crystallization of salts.
Comprehensive Instrumentation Panel with all necessary measuring instruments & Safety Devices.

Tesca Cooling Crystallization Unit is designed to demonstrate process of crystallization of dissolved substances from solutions to be transformed into a solid and separated. A pump delivers a saturated potassium sulphate solution in a circuit with a tank. To prevent premature Crystallization, the solution is heated above saturation temperature using a heating circuit. Both circuits are connected by two heat exchangers. A small amount of this under saturated solution is fed through the crystallization cell as a bypass. To crystallize this part of solution, it is cooled by cooling water using two heat exchangers. Reducing the temperature converts the solution into an oversaturated, metastable state
Detailed Operation & Maintenance Manual is provided along with the trainer.
