Digital Distilling Unit- Super Dee With Or Without Vade

In compliance with the official methods for the determination of the alcoholic strength by volume in wines, musts and spirits (Regulation OIV) and of the volatile acidity.

COMPLETELY AUTOMATIC INSTRUMENT that allows to obtain a distillate of wine, spirits, scents or other alcoholic solutions to determinate alcoholic strength by volume.

INTEGRATED STEAM GENERATOR directly connected to tap water, with user replaceable demineralisations column (autonomy 100 litres – approximately 400 analyses of volatile acidity). There is no more need of distilled water. After the distillation the instrument automatically locks to avoid any waste of water.

Available also without generator (mod. SDEE/SV).

EXECUTION TIMES
  • Distillation of wines: 100 ml in 3÷4 minutes – 200 ml in 6÷7 minutes
  • Volatile acidity: 250 ml in 6÷7 minutes

Distillation of spirits: 4÷8 minutes
