The 50L fractional (reflux) still "Alex 50" is a scaled-up version of a small 25L "Alex 25" distiller. However, both stills share the same construction principles. They differ by size and power consumption, so the amount of alcohol produced varies. The 50L still consists of the 50-liter boiler equipped with one 3kw heating element or two 1.5kw heating elements( now 4 x 800w high temperature tolerant stainless elements). The pot can be heat-insulated to preserve all the energy applied to the distiller. The boiler also has a waste release valve, column mounting neck, and separate loading neck.

While both 25L and 50L alcohol stills share a 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 of cooling down the increased flow of the distilled ethanol.

The columns of the 50L alcohol distiller are taller, and they have a greater diameter to handle increased internal vapor and liquid flow.

The "Alex 50" 50L fractional alcohol distiller can produce 3L of pure alcohol (ethanol) per hour. If exploited with a small continuous distillation unit, it can make enough in one go to make up to 40L 0f 40% vodka or other alcohol-based drinks per run. Same as the "Alex 25" 25L fractional alcohol distiller, the 50L still can produce 95% alcohol (ethanol), which can be used either as fuel or as a base for alcoholic drinks production.

 The "Alex 50" still also can be equipped with a bigger capacity infusion chamber (sold separately)

 for herbs' infused alcoholic drinks production - gin for example.
