The 50L fractional still "Alex 50" is scaled up version of a small 25L "Alex 25" still, though both stills are share the same construction principals they are different by size and power consumption and as a result the amount of ethanol produced is different. The 50L fractional still consist of the 50 liter boiler that can be equipped with one 3kw heating element or two 1.5kw heating elements, the boiler can be heat insulated to preserve all the heat that applied to the still, the boiler also equipped with the waste release valve, column mounting neck and separate loading neck.

While both 25L and 50L stills are share similar construction , the heat exchangers of fractional and stripping  columns' of the 50L still are constructed differently from the 25L heat exchangers, - to be capable to cool down increased flow of the distilled ethanol.

The columns of the 50L fractional still have bigger height and diameter to handle increased internal vapor and liquid flow.

The "Alex 50" 50L still is capable to produce 3L of purified ethanol per hour , if exploited along with a small continuous still it can produce enough in one go to make up to 40L 0f 40% vodka or other alcohol based drinks. Same as "Alex 25" 25L fractional still the 50L still is able to produce 96% ethanol, that can be used either as a fuel or as a base for alcoholic drinks production. The "Alex 50" fractional still also can be equipped with a bigger capacity infusion chamber (sold separately)

 for herbs infused alcoholic drinks production - gin for example.
