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.

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.

Oeno₂user manual

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.
Fig. 5
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.

Oeno₂user manual

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.

Oeno₂user manual

MOD: by clicking on this pictogram, the batch of wine selected can be modified (first, select a
batch in the list by clicking on it to highlight it in blue); a window comes up in which the batch
code, type and/or litres can be modified. When these modifications are complete, click on the
Ok pictogram to confirm, or cancel the operation by clicking on the Cancel pictogram.
DEL: click on this pictogram to remove the batch of wine selected (first, select a batch in the list
by clicking on it to highlight it in blue).
Bottom right, the ‘Exit’ pictogram takes the user to the general visualisation page.
Fig. 7
6) Graph page
This page (Fig. 8) displays graphs corresponding to the operations carried out.
The start date of the operation to be visualised must be selected. A batch of wine can be selected
to limit the choice to only operations carried out on this batch; to select a batch, first click on the
bullet before ‘Batch’, then click on the scrolling menu of the list of batches.
Once the required operation has been selected, the system extracts the data corresponding to the
operation (wait a few seconds). On the graph page, a caption appears that displays the system
parameters: input pressure, output pressure, temperature, flow. Clicking on one or more terms in the
caption will display the graphs.
7) Error management
Fig. 8

Oeno₂user manual
10
Should an error occur during oxygenation, oxygen distribution stops and the screen displays an
error page. The ‘CONT’ option can be selected to attempt to restart the paused oxygenation, or
the ‘EXIT’option to end the job.
The error page also displays the type of error encountered:
•HI TEMP: the gas temperature is too high (max. 50°C)
•LO TEMP: the gas temperature is too low
•LO IP: the input pressure is too low
•HI IP: the input pressure is too high
•LO OP: the output pressure is too low
•HIGH OP: the output pressure is too high
•PRESS JUMP: there has been a sudden variation in pressure
During oxygenation, if the apparatus is accidentally turned off or if there is a power cut, when the
apparatus comes back on, the page for the suspension of oxygenation in progress before the halt
will appear, to enable a restart from the point at which it was paused.
Cleaning the diffusers
(Clean the diffusers thoroughly before long-term storage)
1) Stainless-steel diffusers
Prewash with water
Immersion for 30 to 45 minutes in 2-4% NaOH
Rinse with water
Buffer with a citric-acid solution at 2-3%
2) Ceramic diffusers
Prewash with water
Immersion for 60 to 90 minutes in 0.5-1% KOH
Rinse with water
Buffer with a citric-acid solution at 2-3%
Remark: for blocked diffusers that are very hard to clean, use an ultrasonic bath (there is a charge
for the diffuser cleaning service) or replace only the porous part.
Technical notes on oxygenation
Over the last few years, the use of micro/macro-oxygenation techniques has become
customary in winemaking. It results from an understanding of the positive action of oxygen in
improving the characteristics of wine. Already in 1866, Pasteur recognised oxygen’s ability to refine
wine, particularly by modifying sour aromas and alleviating unpleasant tastes. Among their other
advantages, permeable casks release very small quantities of oxygen into wine with slow diffusion
over time.In casks, oxygen supply occurs during racking, which –depending on the method –can
enable limited or large quantities of oxygen to dissolve. These techniques cannot be used to supply
wine with a predetermined quantity of oxygen, but that is possible with modern micro/macro-
oxygenation systems.
The oxygen supplied is measured in milligrams per litre of wine over a unit of time. The two
processes of micro and macro-oxygenation essentially differ in the length of operation and the
scale of the volume of oxygen supplied to the wine.
Macro-oxygenation
In general, macro-oxygenation lasts for a day. During that time, it supplies a considerable

Oeno₂user manual
11
quantity of oxygen measured in mg/l/day. It is generally done during the final phase of
fermentation or to replace aeration.
During this phase, the oxygen enables the yeast to complete alcoholic fermentation evenly,
avoiding the formation of sulphur compounds which could cause unpleasant odours and tastes.
Also, the presence of oxygen increases the production of acetic aldehyde or acetaldehyde. The
compounds plays a very important part in developing colour, since it bonds to the phenolic
anthocyanin-tannin complex; once the bond is formed, the normally colourless complex recovers
its positive charge, restoring stability and the original colour.
Micro-oxygenation
Generally, micro-oxygenation lasts for a month, supplying a small quantity measured in
mg/l/month.
During the production of very high-quality wines, the use of oxygen can be crucial. Oxygenation
during the phases immediately following the end of fermentation improves the stability of the
colouring matter, avoids the formation of sulphur compounds and encourages polymerisation and
the condensation of tannins. During the élevage phase in casks or oak barrels, oxygenation softens
and rounds off wine that has not matured in terms of tannin (astringency and bitterness). Before
bottling, oxygenation helps a wine to achieve balance and makes the tannins more flexible.
To carry out oxygenation operations, it is necessary to consider the following aspects:
Wine rapidly consumes dissolved oxygen; if the quantity of oxygen supplied is no greater
than the wine’s capacity to consume it, there is improved stability of the colouring matter
and development of the taste, as described above. If, on the contrary, the quantity of
oxygen supplied per unit of time is excessive, the gas will accumulate in the container and
could cause violent, harmful oxidation.
The temperature of the wine to be treated must not be lower than 10°C or the speed of the
chemical reactions will be too slow and the solubility of the oxygen too high.
Distribution must be continuous and the bubbles very small in order to allow them to dissolve
completely in the wine.
To control the process efficiently, certain physicochemical parameters of the wine must be
periodically checked. It is possible to directly verify the quantity of oxygen dissolved in the
vat, but the equipment needed is not yet easily available in cellars.On the other hand, it is
possible to check other parameters that are more easily determined, such as acetaldehyde
or volatile acidity. Indeed, a higher concentration of acetaldehyde than 30 mg/l may be
due to an excess of oxygen, which may contribute to the development of a musty odour.
The verification of volatile acidity can be useful in controlling the formation of acetic
bacteria, particularly on the diffuser or the surface of the wine –a sign of oxygen
overdosing. The criteria that enable simpler monitoring of the development of the process
are those of colour, especially absorbance at 620 nm, which reveals the formation of
purplish pigments. They result –as has already been underlined –from the formation of more
stable complexes among the molecules of colouring matter.
The wine’s development is appreciable in organoleptic terms –as already stressed –for
greater opening up of the aromas towards fruity notes and a general softening of the
flavour. So frequent tasting is needed to assess evolving changes in the wine.
Remarks
1. Do not use the system in a hermetically enclosed space; enable air circulation
and the possible dispersal of oxygen in case of a leak.
2. Do not use products and materials that are incompatible with oxygen, particularly grease or
lubricants.
3. In contact with oxygen, grease can catch fire. Consequently, be very careful not to have
greasy hands or other greasy objects present when handling oxygen.

Oeno₂user manual
12
4. is designed and tested to work optimally with an input oxygen pressure of 5 bars;
distribution will be halted if the input pressure is lower than 4 bars or higher than 5.5 bars. In
no case should the pressure exceed 6.5 bars.
5. Never use the system in a place where there is a risk of fire or explosion. Always use the
system in a managed area.
6. In case of functional anomalies, do not use the system and disconnect it from the oxygen
supply and power network.
7. The oxygen contained in high-pressure bottles can cause explosions if not handled with
care. The final user must read the instructions and explain the use and maintenance of the
bottles containing the gas to the relevant staff.
8. Oxygen is a gas that can very quickly fuel fires, so the user must be extremely attentive
during the installation of the appropriate pipes to carry the gas to either the doser or the
dosing tube.
9. The continuous inhalation of a concentration of oxygen greater than 75% can cause
nausea, dizziness, breathing difficulties and convulsions. If such symptoms are experienced,
take the necessary steps in the area and put the operation on hold until conditions are safe
again.
10. Compliance with regulations pertaining to the handling and storage of oxygen in any form
is the exclusive responsibility of the user, as is the relevant staff training.
11. Mono-dose and bi-dose machines are equipped with a safety system to handle any excess
pressure that may occur inside the vat. Be very careful to check the proper state of the
membrane and free it of any obstructions.
12. The output pressure is the minimum one for distribution; it depends on atmospheric pressure,
the height of the liquid in the vat and the type of diffuser. So before beginning diffusion, the
system’s output circuit must reach that pressure. If the dosing is low, that phase may require
a long wait; to limit the delay, the tube can be filled preventatively.
13. Since oxygen dosing is continuous, the system is sensitive to variations in input and output
pressure. In case of slow variation –for instance the progressive blockage of the diffuser –
automatically compensates within certain limits by maintaining a constant
distribution rate.
14. Variations in output pressure –for instance an increase in atmospheric pressure –can result
in very low dosing and the momentary interruption of distribution until the tube pressure
returns to the proper level.
15. If the pressure variation is very rapid –for example because of irregular supply –the system
automatically blocks distribution to avoid risks of malfunction (if the input pressure is rapidly
increased during distribution or if the valves that regulate flow detect significant vibration,
etc.) In all such cases, the error is displayed as ‘System failure’. To avoid remaining
stopped because of accidental vibration, an automatic restart system is built in. This system
restarts distribution after a minute of stoppage; if the same error occurs again in the minute
following the restart, distribution will again be halted and begin again. In case of a third
consecutive error, following a restart attempt, will permanently stop distribution
until the user takes action, and report the error. However, if after a restart, the system
continues its normal distribution for at least a minute, that means the problem was
momentary and operation will continue as normal (the error will not be reported).
16. If apparatuses are on trolleys, the user is advised to avoid moving them during operation as
excessive vibration could prevent regular dosing; in addition, care must be taken when
moving them because excessive or frequent knocks could damage the regulation systems.
17. The system does not operate if the input pressure exceeds 6.5 bars, whatever the reason.
18. has been calibrated for doses of 2 mg/l/month for 10,000 litres
19. NEVER REVERSE oxygen input and output; that could damage the apparatus.
20. We recommend checking the diffuser periodically and cleaning it if necessary. It should be
cleaned with food-grade ethanol before use and left immersed in a 25% solution of alcohol
in water for at least 24 hours.
21. We advise installing a check valve between the diffuser output and the dosing input to
ensure that, in case of malfunction, the contents of the vat cannot leak through the gas
tube and damage the apparatus.

Oeno₂user manual
13
22. If there are a number of distribution points, they are all completely independent of each
other. Because of the tolerances of the internal clocks of the microprocessors that control
the apparatuses, the execution time of oxygenation operations can show differences, but
in no case will that make the system less effective.
23. Possible difficulties with spikes in the power supply can cause dysfunctions and/or system
problems that may be difficult to identify. Consequently, in case of abnormal conditions,
use a UPS-type voltage regulator (see computer systems) which will power the apparatus
directly. The voltage regulator should have the right power output (VA –volt ampere)
corresponding to the apparatus’s consumption. Finally, it should have the appropriate
voltage and phase, while producing the power-supply voltage required by the doser, the
frequency and also the correct sinusoidal signal form.
24. To ensure optimum distribution of oxygen bubbles, the air-passage pores in the dosing input
(passage diameter from 1 to 5 microns) should be clean and free of any obstructive
particles (e.g. grease from incomplete cleaning with soap or contact with dirty hands).
Cleaning of the diffusion surface is advised before dosing begins. That operation must be
done using substances acceptable for food-grade contact (e.g. a solution of water and
food-grade ethanol) so as to remove any traces of grease (which is incompatible with
oxygen because it can catch fire). It should be remembered that even small particles of dirt
can compromise the system’s efficacy, since in case of blockage, the pores of the dosing
output cause increased pressure and so an increase in the diameter of the oxygen bubbles
diffused, leading to less solubility in the liquid and possible accumulation on the surface,
which, depending on the concentration, could cause oxidation of the wine. Cleaning
could even be necessary when the diffuser is in use. Oenofrance declines all responsibility
for the use or possession of the substances used.
25. If the user anticipates not using the for a prolonged period, it is advisable to
disconnect the gas input and output tubes and start oxygenation for a short time (the
system will report a low input pressure error) or alternatively, if available, activation of the
draining function. The procedure is needed to empty the apparatus of any volumes of gas
at operational pressure. If there are a number of stations, the recommended action should
be repeated for each output left inactive.

Important notes
Coverage
1. The apparatus has been designed and constructed exclusively for the dosing of oxygen in
winemaking, subject to testing for input pressures no higher than 7 bars. Before connecting
the apparatus, check that the pressure supplied corresponds to the one indicated (about 5
bars).
2. NEVER USE the apparatus to dose gases other than oxygen; they could be corrosive and
harm parts of the system or persons.
3. Should the apparatus malfunction, disconnect it from the oxygen supply and power
network.
Protection of the gas bottle
1. Fix the bottle in a stable place to prevent it from slipping.
2. Check that the valve of the bottle shows no signs of damage or defects, or dirt, dust, oil or
grease (if present, remove them). DO NOT CONNECT IT if it shows signs of the presence of oil
or grease, or if the pressure-reducing valve is damaged; inform the gas supplier of any
problems. In the presence of high-pressure oxygen, oil or grease can be an explosive mix.
Oxygen
1. Pure oxygen burns quickly, like any other inflammable material or gas.
2. NEVER USE the oxygen to blow-clean parts or dust down clothing.
3. NEVER GREASE the oxygen or connector equipment.
4. Follow the instructions supplied by the constructors of the bottle and pressure-reducing
valve.
5. NEVER USE pressure-reducing valves for air on oxygen bottles.
6. It is advisable to use flow-check and flame-blocking valves on all oxygen pressure-reducing
valves.
Conservation, storage and transport
1. Keep in a clean, safe place at a temperature between 5° and 45°C and with an air-
humidity level no higher than 65%.
2. Avoid exposing the apparatus to excessive vibrations or knocks, since they could harm the
mechanisms.
3. Transport should take the above points into account.
Maintenance
1. Before use, check the state of the valves and for any leaks.
2. Each month, check or recharge the battery.
