CHEM Crystallisers are used to crystallise the salts and recover them from its mother liquor in various industries like Chemical, Pharmaceutical, Agro-chemicals, Dyes, Dyes Intermediates, Synthetic Yarn, etc. The product range includes Single / Multi-Stage Crystallisers for extracting useful chemicals (viz. Sodium Sulphate, Calcium Sulphate, Sodium Chloride, Calcium Chloride, Sodium Thiosulphate, Aluminium Chloride, Magnesium Chloride, Sodium Acetate, etc.) from process solutions and effluents.

The design and operation of the crystallizers are difficult tasks since the crystallization process has to produce crystals having the required purity, size distribution and habit. Moreover complex phenomena occur simultaneously during the crystallization operation, such as nucleation, crystal growth and crystal breakage and agglomeration. For these reasons the design and operation of a crystallizer has been considered more an art than a science. Chem Process Systems has mastered the skills of crystallization of a variety of products not only because of its broad technical base but also because of varied experience in diverse industries.

Our research projects at our in-house test laboratory concentrates on developing new knowledge and tools for industrial use. These are aimed at controlling the particle characteristics of bulk materials produced in agitated suspensions by crystallization and precipitation. Physical characteristics as crystal size, shape and structure are important industrially in determining both downstream processing performance and product quality. Chem Process continues to develop crystallization solutions as per requirement with due investments in research and testing of complex liquids and solutions

The Chem experience covers different products through more than 150 plants and over 1000 in-house tests. This in addition to the practical experience gained over the last 2 decades has made Chem Process the leader in India in the field of crystallization equipment and solution design. Chem has the know-how and the essential experience for the design and supply of all the types of crystallizers for industrial processes.

Evaporators and Crystallizers supplied by CHEM are working very efficiently in numerous plants with varied applications. Energy conservation is as important in the design of evaporative crystallizers as in the case of any non-crystallizing evaporator. Both Draft Tube Baffle and Forced Circulation Crystallizers are frequently built as multiple effect or recompression type.
Chem designs and manufactures the following types of Crystallizers:
