Crystalline products, of varying compositions and capacities, to complex organic polymers are produced in Buflovak Crystallizers. Available as Tubular Surface Cooled or Vacuum-Flash type.

Evaporative crystallizers tend to yield larger average crystal size and narrows the crystal size distribution curve.

Tubular Surface or Vacuum Cooled Crystallizers are usually considered for materials having a solubility curve with a steep slope. Crystal size desired and the temperature level and nature of the solute usually determines if a vacuum or surface cooled unit is applied.

Liquid is pumped through tubes at controlled velocities to provide a high rate of heat transfer, rapid evaporation and high concentration without requiring high operating temperatures or large heating surfaces. Since no boiling occurs in the tubes, fouling is reduced or eliminated. Main applications are in the concentration of inversely soluble materials, crystallizing, and concentration of thermally degradable materials. Common uses are for caustic soda, waste streams and inorganic acids.

• Operates at extremely low temperature differences
• Suppressed boiling prevents evaporation in tubes, reducing scaling and fouling
• Operates as an evaporator/crystallizer.
