OENO2: what is it?
is a system that manages the micro/macro-oxygenation of wine in vats while measuring
effective oxygen supply in mg/s. It does not require particularly high input pressures and
compensates for any variations in output pressure (independently of the input pressure) in order to
stabilise the oxygen supply throughout the distribution period. Equipped with an efficient self-
diagnosis system and specific safety systems, it immediately halts distribution in case of any
dysfunction.
allows the user to carry out three kinds of oxygenation:
MICRO micro-oxygenation lasting one month (in mg/l/month)
MACRO macro-oxygenation lasting one day (in mg/l/day)
PERS oxygenation for a personalised period (in mg/l/desired time, with a minimum
possible)
The user must determine the dose of oxygen to be diffused by weight. Indeed, defining doses by
volume is not very appropriate, since the number of chemical reactions occurring depends on the
number of oxygen molecules supplied, and so the weight of the quantity of oxygen distributed.
There can be more or fewer molecules in the same volume of oxygen (so the weight will be
different), depending on temperature and pressure.
The user then identifies the number of litres of product to be oxygenated. The system automatically
calculates the total weight of oxygen to be supplied and controls distribution according to the type
of oxygenation selected (micro, macro, personalised) and according to the desired length of time.
The system ensures regular, continuous distribution. It does not use dosing chambers,
but sensors that measure gas flow in real time. The powerful microprocessor and extremely
sophisticated software perform the calculations needed to make sure the system maintains oxygen
flow in weight at the required value.
There are many advantages to this type of technology:
Greater regularity of distribution.
Elimination of mechanical elements in the system.
Reduction in the value of input pressure needed for the proper operation of the system.
Minimal working pressure on the diffuser: the oxygen is distributed at the lowest pressure
needed in order to minimise the size of the bubbles and improve oxygenation yield.
Immediate automatic compensation of variations in pressure: the system adapts
automatically to variations in output pressure (for instance due to clogging of the diffuser or
atmospheric pressure), by consequently varying the flow of gas in volume to stabilise flow in
weight. In addition, it can also compensate for variations in input pressure while ensuring
continuously stable output diffusion. If the system is unable to compensate, diffusion is
immediately interrupted and the type of error is displayed on the screen.
It is possible to use any kind of diffuser (changing the diffuser has an impact on the
diameter of the oxygen bubbles).
The scale of dosing depends on the version of the apparatus: from 0.1 mg/l –min. dose 1
mg/l/month for 200 l; max. dose 9 mg/l/d for 500,000 l.

OENO2installation
To install the standalone system, follow the procedure below (see the connection
diagram Fig. 1):
Fig. 1
1. Locate the apparatus in a vertical position in an appropriate area, generally near the vat to
be oxygenated.
2. Connect the gas input to an oxygen bottle with a pressure-reducing valve (PRV).
3. Regulate the output pressure of the bottle to around 5 bars –the pressure that ensures
optimum operation. The system halts distribution if it detects an input pressure lower than 4
bars or higher than 5.5 bars. (The input pressure is shown on the touch screen once dosing
has begun.)
4. Connect the gas output to the diffuser with the special tube.
5. It is advisable to place a check valve between the Oeno2 output and the diffuser to avoid
the contents of the vat leaking through the gas tube and damaging the apparatus in case
of malfunction.
6. Insert the diffuser into the vat to be oxygenated.
7. Plug into the 220 V network.

Use of OENO2
Install the system as described in the paragraph above.
The system is controlled by touch screen. Using the screen, it is possible to control a number of
dosing outputs or units present (up to a maximum of 30 systems on a single frame).
Fig. 2 illustrates the pattern of connection with connectors mounted on a single frame
and linked to a touch screen. Each distribution point is controlled independently, so it is possible to
simultaneously regulate and apply different dosing values for the vats in the cellar.

1) General visualisation page
When the screen is turned on, data related to the apparatuses in the network are read and a page
is displayed that illustrates the state of each one (Fig. 3). Each is represented by a tank
pictogram. The icon changes according to the state of the apparatus: oxygenation in progress is
represented by bubbles; oxygenation on hold by the pause symbol; an alert by a red triangle. The
type of operation in progress or programmed is shown:
-‘MICRO’for micro-oxygenation,
-‘MACRO’ for macro-oxygenation,
-‘PERS’ for personalised oxygenation.
Top right: the code of the apparatus (number from 1 to 9999). By clicking on the pictogram of one
of the apparatuses, the user can access the page related to its operation.
Top right: a pictogram provides access to the general parameter page.
If the system runs more than 10 systems, each page enables the control of 10
apparatuses at most. In that case, bottom right, there will be 2 pictograms with arrows pointing left
and right to move through the pages.
Fig. 3
2) Operation page
This page is used to set the operational parameters for one of the systems (Fig. 4).
Top left: a status bar appears. It shows the state of the apparatus. On the right is the output
number. The icon below changes according to status: inactive, distribution in progress, paused,
etc.
Under the status bar, there is information related to the type of operation selected, dosing and litres
of product. Below is the total duration of oxygenation programmed, time since the start (0 if the
apparatus is inactive), the total dose programmed and that supplied since the start of oxygenation
(0 if the apparatus is inactive). Below are displayed the temperature and input and output pressure
of the apparatus. At the bottom are pictograms to control the operation of the system:
Filling the tube
The filling function injects oxygen into the tube to fill it. Clicking the pictogram once starts the
distribution, clicking a second time blocks it. After 30 seconds, distribution will be interrupted.

Emptying the tube
Clicking on this pictogram empties the apparatus of any oxygen present in the internal pipes.
The emptying operation lasts about 1 second and can be repeated a number of times, simply
by clicking on the pictogram.
WARNING: BEFORE EMPTYING, DISCONNECT THE APPARATUS’S INPUT AND OUTPUT TUBES.
Oxygenation parameters
Clicking on this pictogram takes the user to the operational parameter page (see the
paragraph concerned for more details). If the system is paused, clicking on this pictogram takes
the user to the intermediate personalised operational parameter page.
Start
Clicking on this pictogram will begin the programmed oxygenation if the is inactive. If
the is paused, oxygenation will begin again.
Pause
Clicking on this pictogram interrupts the oxygenation in progress.
Stop
Clicking on this pictogram cancels the paused oxygenation and deactivates the apparatus. To
cancel oxygenation, first interrupt it by selecting the ‘Pause’ pictogram and then press ‘Stop’.
This two-stage procedure is a safety measure to prevent cancellation of the operation by
accidental selection of the pictogram.
Exit
Clicking on this pictogram takes the user to the general page.
Graphics
Clicking on this pictogram takes the user to the graphics page.

3) Parameter page
On this page (Fig. 5), the user can programme oxygenation via the selected output.
Top right is the output number. Below, there are three pictograms to select the type of operation to
be carried out:
MICRO micro-oxygenation lasting one month in mg/l/month
MACRO macro-oxygenation lasting one day in mg/l/day
PERS oxygenation with a maximum duration of one day, with personalised dosing in mg/l
According to the type of operation chosen, the display of the unit of measurement (in the ‘DOSE’
box) will be different. Clicking on this box gives access to the keyboard. Then the dose to be used
can be entered. The system accepts doses from 0.50 minimum to 99.00 maximum. Next, the litres of
product to be oxygenated must be chosen by clicking on the ‘Litres’ box and entering the required
value; the system accepts a value of 200 litres minimum; the maximum varies according to the
programmed dose, but will never be higher than 500,000 litres. Next, the duration of oxygenation
must be chosen: for micro or macro, the maximum duration is 60 days and 1 day for personalised
operation.
Clicking on the ‘Start’pictogram starts oxygenation and the user returns to the control screen.
Clicking on the ‘Exit’ pictogram takes the user to the control screen without starting
oxygenation.

4) Parameter page for intermediate personalised dosing
This page (Fig. 6) is used to programme personalised oxygenation to be carried out during an
interruption of the oxygenation already begun.
Top right is the number of the output controlled. Below are the boxes to select the dose, number of
litres and duration of the operation:
Dose: the system accepts values from a minimum of 0.50 to a maximum of 99.00
Litres: the system accepts values from a minimum of 200 to a maximum that varies according to
the chosen dose, in no case higher than 500,000.
Duration: the maximum duration is one day; the minimum varies according to the dose and
litres entered so as not to exceed the maximum flow of distribution.

Then the ‘Automatic resumption’control must be chosen. If ‘False’(empty circle) value is chosen, at
the end of intermediate oxygenation, the system will return to the interruption phase of the
previous, paused operation. If ‘True’(full circle) is chosen, at the end of oxygenation, the system will
return to the previous, paused operation. For more details on personalised intermediate operation,
read the relevant paragraph of this manual.
Bottom right are two pictograms:
clicking on ‘Start’ begins oxygenation and the user returns to the control page,
clicking on ‘Exit’ takes the user back to the control page without starting oxygenation.
Fig. 6
5) General parameter page
This page (Fig. 7) displays two screens; two system configurations can be handled:
General: this screen is used to set system management parameters.
Batches: this screen is used to enter, modify and delete batches of wine.
With the ‘General’screen, the following parameters can be set:
Number of outputs: the value set must correspond to the number of connectors present in the
system. WARNING: NEVER MODIFY THIS VALUE WITHOUT HAVING EXPANDED THE SYSTEM BY
PHYSICALLY ADDING OTHER CONNECTORS TO THOSE INITIALLY PRESENT. Entering a lower value
than the number of connectors present will not cause the system problems, but the user will only
be able to control some of the connectors. Entering a higher value than the number of
connectors present could lead to system control problems.
Time between two recordings: in a database, the system memorises the state of the connectors
at regular intervals, corresponding to the value of this parameter (minimum 10 minutes).
Language: click on this box to select the desired language.
Date/Time: when the user clicks on the date, a calendar allows it to be modified. To change
the system time, click on the hours and use the arrows to change them; to modify the minutes,
click on the minutes and use the arrows to change them.
The ‘Batches’ screen displays the list of batches of wine entered. At the bottom are the following
pictograms:
ADD: click on this pictogram to add a new batch of wine; a window is displayed where the
batch code, type and litres can be added. After adding this information, confirm it by clicking
on the Ok pictogram or cancel the operation by clicking on the Cancel pictogram.
