W6 Chemical
High purity product and low energy consumption are key properties of the melt crystallization process. The efficiency of chemical purification operations can be increased through crystallization. GEA Niro PT has several pilot units available (Download our brochure) to demonstrate the feasibility of our crystallization process on a wide range of chemicals. Some successful applications with melting points from -45°C to over 130°C include:

W6-Chemical
The standard pilot plant for new applications of melt crystallization. The W6-C is suitable for all chemical applications with melting points from +150°C to -60°C. Test work can be completed at GEA Niro’s
W6 for chemical applicationspremises in The Netherlands or if required can be shipped anywhere in the world. The unit is completely self-contained, requires only standard utilities (electricity, compressed air and cooling water), explosion proof (ATEX II3G IIB T2) and can therefore be installed in most industrial locations.
W6-3
Our standard freeze concentration unit but used exclusively for the chemical waste water applications. This unit is configured for applications with industrial waste water. Chemical waste water may be difficult to ship to us as it is typically considered a hazardous product. This skid unit is also self-contained and can be easily installed on-site in just a few hours. It includes options to allow testing different equipment configurations. The data collected from a test run can be used to accurately design a full scale industrial unit.
W60
Wash column / Continuous wash column separation unit available for connection to existing
W60 Washcolumn for chemical applicationscrystallization systems. The W60 wash column is not a self-contained unit but can be installed slip-stream to an existing crystallizer. The results of a test run can be used to compare the efficiency of wash column separation with the existing centrifuge or filtration system.
Please contact us for a detailed test proposal for any of the above mentioned units
