If the drink is already stored under pressure, it can flow directly to an isobaric filler, there is no need for a pump.
Alternatively, carbonation can be carried out automatically in the filling line.

To avoid excess foaming the temperature of the liquid (when inside the filler's header tank) should be between - 3 °C and + 4 °C; ideally 2 °C.

If there are problems with foam in the filler or after filling (between filler and corker) it depends on different factors:-

Cooling down the drink (to a temperature around 2 °C) before filling is more important for the foaming aspect than the type of valve used for filling.
At 2 °C there will be good impregnation of the gas when inside the carbonator, afterwards the drink will be more stable during the filling process.
The amount of sugar in the drink and the fineness of it's filtration have a big influence on the stability. Gases other than CO₂ already present in the drink have a detrimental affect.

EN monobloc EDO 6 ISO R TPGB: automatic bottle filler with corker and wire muzzler, 39,295 Euros

An in-line version of the EDO 6 ISO R isobaric filler, combined with the TPGB 400 corker and wire muzzler.

Throughput of 300 to 500 bottles/hour.

There is a station for injection of inert gas into the bottle before the filling. Any type of inert gas can be used; usually it's Nitrogen.
The quantity of gas is adjustable easily and quickly. It’s really only needed for still wines, so it's possible to activate or to disarm this station.

Compressed air: max 6 bar. Consumption of air: max 10.4 Nls.
Three-phase 380 Volts, 1.5 kWatt. 910 x 1700 x 2050 mmH. Weighs 580 Kilos.

Careddu Gold:-

These are 'very heavy duty' machines, made to the same quality as very large automatic machines (with 30 filling nozzles).

There are various choices for the filling valves:-

Standard 'S' valves. 3 stages: pressurisation with CO₂, filling, snifting.
'SL' valves. 4 stages: pressurisation with CO₂, filling, levelling, snifting.
'PS' valves. 4 stages: pre-evacuation, pressurisation with CO₂, filling, snifting.
'PSL' valves. 5 stages: pre-evacuation, pressurisation with CO₂, filling, levelling, snifting.
'DPS' valves. 6 stages: pre-evacuation, rinsing with CO₂, second evacuation, pressurisation with CO₂, filling, snifting.

The type of valve chosen is important for reducing oxidation during the filling process, rather than any affect on foaming.
Pre-evacuation (removing air from the bottle, leaving a vacuum) is a great help to avoid oxidation during the filling process.
The SL and PSL valves make an additional levelling of the fill level.
For filling beer, the recommendation is to use PSL or DPS valves.
It's not easy to change just the type of valves later on; the header tank and the valves would need to be changed together.
There are large differences between the prices of the different valves.

The number of bottles per hour through the line is not easy to say. It depends mostly on whether the drink is foaming or not.
The valves with more stages have less time for the filling, so less bottles per hour are filled.
With 12 filling-valves, up to 1800 or even 2000 330 ml bottles are possible per hour. With larger bottles it will be much less.
With 8 filling-valves it can be 800 to 1200 bottles per hour.

You cannot easily open the tank of an isobaric filler for cleaning. Therefore CIP is essential.
The Kit of false (dummy) bottles and the Fittings for CIP (cleaning in place) include everything needed on the filler for CIP.

Isobaric 8 bottle filler, with Standard 'S' valves, and crown capper,  64,579 Euros

Isobaric 12 bottle filler, with Standard 'S' valves, and crown capper,  83,890 Euros

Isobaric 16 bottle filler, with Standard 'S' valves,  88,000 Euros

Isobaric 16 bottle filler, with electro-pneumatic valves, 139,590 Euros

Isobaric 20 bottle filler, with Standard 'S' valves,  110,000 Euros

Isobaric 20 bottle filler, with electro-pneumatic valves, 169,500 Euros

Options for these isobaric fillers:-

Tank for CIP cleaning (including pump, heating elements and control panel), 6420 Euros
The CIP cleaning tank is a stainless steel tank with heating elements, float, pump, and is controlled from the control panel of the filler. From the control panel you can start the automatic cleaning with re-circulation etc.
Note: instead of the above you can use a plastic tank with hot water, add a cleaning product, then pump it with re-circulation.

Pressure gauge in the filler tank, 320 Euros

Fully automatic integrated crown capper, 26 mm diameter caps, 18,175 Euros

Fully automatic integrated ROPP capper, 19,900 Euros

Next in the line can be an automatic labeller but it must be preceded by a bottle dryer,
because the very cold bottles will have a lot of condensation on the outside, which would prevent the labels from sticking to the glass.

Bottle dryer, 8600 Euros       
complete installation with hot air blowing unit 7.5 kWatt (with frequency converter for control), parts for installation, pipes and two air knives.
Will work for a line up to 1500 bottles/hour. Delivery time is about 5 to 6 weeks from order.
