Yamato CF Series Refrigerated Water Circulators



Powerful and water saving closed cooling system with excellent cooling capacity


  • Environment friendly coolant used for refrigeration
  • Waterproof touch panel with big LED display and sheet key for easier setting
  • Less energy use and less cooling capacity loss by fixing the heat-resistant lid
  • Powerful cooling and big energy saver in combination with rotary evaporator distillation
  • When using CF800 up to 4 rotary evaporators can be connected saving investment and operation cost
