Alfatek patented system - during the filling phase, by means of a high vacuum pump, performs the pre-conditioning (single or double) of the air from the bottle subsequently subjected to saturation with inert gas.
Avoids the dispersion of dissolved fragrances, aromas and gases contained in wines processed, as well as preventing oxidation caused by the introduction of oxygen.
Conveying in a special tunnel saturated with inert gas protects against reintroduction of air in the bottle neck during translation.
