CHEM designs and manufactures diverse types of Crystallizers, which includes the Adiabetic Vacuum  Type, Evaporative Forced Type, Draft Tube Baffle Type, Spray Evaporators Type, Oslo Type, etc.

The other type of Crystallizer designed and manufactured by Chem is the Batch Vacuum Crystallizer which is appropriate where the operating temperatures are very low and achievable only by exceptionally high vacuum. The Batch Crystallizer is preferred as it costs less to operate than a Continuous Vacuum Crystallizer.

Chem also designs the Surface Cooled Crystallizer using a Shell And Tube Exchanger, and is applied for operations at temperatures below which it is not economically viable to use vacuum equipment, or with solutions having very high boiling point elevations.

For applications where refrigerants are used to achieve operating temperatures, Chem designs and applies the Direct Contact Type Refrigeration Crystallizer on the principles of  forced circulation or draft tube baffle is used, where the refrigerant is mixed with the slurry.
