Technology adopted in systems for bottling still or slightly carbonated products, such as wines, spirits, etc. for which traditional vacuum or gravity bottling systems are limited or inadequate.
It is characterised by the constant pressure of inert gas aimed at performing important safety actions:
it isolates the product from any contact with the air, preventing both dangerous microbiological pollution as well as oxidation caused by the increase of oxygen during bottling;
it avoids the dispersion of volatile components, preserving dissolved aromas, fragrances and gases and all the organoleptic qualities specific to each product.

The filling valves represent the most innovative aspect of the hyperbaric - low pressure - filler, allowing precise and repetitive levels.
Through the tubes for evacuating the air from the bottle - present on each valve - it is possible to convey the air extracted from the bottles outside the filling tank, avoiding microbiological pollution and contact between the oxygen and the product.
The filling valves are self-levelling.
They allow manual adjustment on every single valve for format change. The machines can be equipped with a device to manage the simultaneous variation of the levels on all the valves (0-80 mm) from the control panel, or with default programming via PLC;
The ring-shaped filling tank, with a hermetic seal, has the internal compartment completely free of the air evacuation tubes, making washing and sterilisation operations considerably easier.
A central resting tank allows the product to settle before being placed in the filling tank.
Recycling washing CIP, without the need for false bottles (Alfatek patent).
