Features

  • Safety features

    A fast tube draining system removes the need for handling hot reagents after distillation. Interlocked safety door which must be closed with a tube in place before the unit will operate. Cooling water flow is controlled automatically and a temperature sensor stops the unit if the distillate is too hot. Sensors monitor tube in place, safety doors, reagent levels, water level and over-pressure in the steam generator providing safe use. 

     

     

  • SAfE

    The patented SAfE* technology improves safety by a mixing procedure, reducing the exothermic reaction between alkali and acid during distillation and removing the need for manual pre-dilution.

     *Steam Addition for Equilibration

Overview of Kjeltec™ models
