No cooling tubes or noisy running water in the plumbing. Thermometers and thermostats are not needed; this unit is designed for the production of alcohol.
All you need to do is add 4 liters of mash or wine to the unit and plug it. The machine warms up in one hour, and the process of distillation takes place in 3 hours. So in 4 hours you can have 1.4 liter of 46% alcohol. If you want a much more pure alcohol, all you have to do is re-distill the outcome of the first batch, and the result will be an alcohol with the 88% of purity.
