Jord is a licensee of Swenson, the recognized authority for evaporation & crystallization. The Swenson name dates back to 1889. The company authored the chapter on crystallization in Perry’s “Chemical Engineering Handbook”.
Evaporisation
Designs include forced circulation , long-tube vertical (both rising and falling film), and calandria-type evaporators. The economics of your particular process will dictate the evaporator style and model best suited to your needs.

Crystallisation
Swenson is best known nowadays for its pioneering technology for production of large, uniform crystals using a Draft Tube Baffle (DTB). Applications include ammonium sulphate, where superior filtration, centrifugation, washing, drying, and storage characteristics are required.
DTB crystallisation is the result of years of research and development as well as proven plant scale operation in more than 300 installations.
Test facilities exist for pilot plant sized vacuum-cooled, forced-circulation, and DTB type crystallizers. Customer processes may be tested in these units, the results compared, and the best design offered for the required product characteristics.
A partial list of crystallisation applications, for which references exist, includes:
