Centrifugal Thin-film EvaporatorsCEH Series

Permitting distillation of highly heat-senstive material (thermally decomposing / polymerizing substances)under vacuum at a low temperature and within a short time.


  • Either of two heating systems can be selected as needed : Indirect heating by a heating medium (CEH-B) or radiant heating by an electric heater (CEH-E).
  • Centrifugal force created by a rotor rotating at high speed on the evaporation surface creates thin, uniform evaporation films.
  • Processing can be performed instantaneously at relatively low temperature in a high vacuum, minimizing quality deterioration due to heat.
  • Models with a circulated heating medium system enable user-set temperatures and highly precise temperature control. Explosion-proof models are available, for processing materials containing solvents.
  • The wide range of supported applications includes concentrating, deodorizing, degassing, solvent removal and desiccating.


  • High vacuum distillation for variou vitamin,DHA,EPA,squalene,oil and fats.
  • Refinery for vacuum pump oil,chiller oil and transformer oil.
  • Fillers for electronics and semiconductors, vacuum heat treatment for mold materials.
  • Refinery for fatty acid amides and other fatty acids.
