Gas management (oxygen, CO2, nitrogen)

Deos® deoxygenation device / controlled oxygenation device

A tool for controlling oxygen in the winery

“Modern” oenology has shown that oxygen management is essential for high-quality ageing of wines. Deos® is the only oxygenation device able to introduce into a vat the correct dose of oxygen in a precise, “gentle” and totally uniform way.

Deos® deoxygenation device / controlled oxygenation device

It is also the only oxygenation device able to deoxygenate, carbonate and decarbonate wine in vats.

Deos® stems from our œnological observations. It was developed to meet the challenges of oxygen inputs. Deos® prevents overexposure of the wine to oxygen, and thus the harmful effects of oxygen use:

degradation of aromatic potential, change of colour, etc.
combination with free SO2
use by micro-organisms present in the wine
energy storage: oxygen would be stored then redelivered and thus available for wine micro-organisms.

Deos® was designed by our design department and production workshop to provide the correct oxygen dose: precisely, gently, uniformly.

precisely: from 5 µg/l to 60 µg/l, thus meeting the “needs” of each type of wine (colour, structure, ageing type and time)
“gently”: the gas added to the wine contains less than 5% oxygen, unlike the use of pure oxygen, contact with which “destroys” wine aromas and flavours
uniformly: the physical process of gas introduction enables each millilitre of wine to “see” the same amount of oxygen
the client can be sure that the input will dissolve fully, as per the principle of oxygen recovery in the headspace.

Deos® also deoxygenates wine in vats, so you can eliminate unwanted oxygen inputs further to:

racking
oenotechnical operations
pumping-over in barrels, to retain the subtle fruit/oak balance acquired during ageing.

Deos® can also carbonate wine up to 1,000 mg/l and decarbonate it up to 400 mg/l in vats.

Deos® has a software program for inertisation and for inertisation control in empty vats.

Deos® adapts to all vat shapes and types.

A compact, mobile tool to work more easily in the ageing facility.

Simple to use, with an interactive interface.

A single device can process a whole facility.

Our range:

Deos® Desox, Deos® Tech, Deos® Pro, Deos® Large Volume : 4 Deos® units to meet all your technical requirements and budget constraints.
