Why GPROKEG

Built for Modern Breweries

Our reusable keg system reduces costs, eliminates cleaning, and supports sustainable operations.

No Cleaning Required

Replaceable inner bags are pre-sterilized and flushed with 99.99% CO2. Simply swap the bag and fill — no chemicals, no water waste.

12-Month Shelf Life

Inner bags provide up to 12 months of shelf life. Pressure medium never contacts the beverage, ensuring freshness is maintained.

100% Recyclable

Fully compliant with EU Directive 94/62/EC. Reduced chemical and water usage supports your brewery's sustainability goals.

Up to 150 Cycles

PRO Series kegs can be reused for 150–200 fillings, making them the most cost-efficient solution for long-term operations.

Compatible Fittings

Available with S type (European Sankey), A type (German Slider), and G type couplers. Works with your existing filling lines.

Flavor Preserved

Pressure medium never touches the beverage, preserving the original flavor. You can even use compressed air instead of CO2.

Frequently Asked Questions

Everything you need to know about GPROKEG kegs and their operation.

The GPROKEG kegs can be filled manually, semi-automatically and fully automatically and are compatible with the existing standard filling lines. More technical information is available per request.
No, the inner bag is prepared with sterilization and air replacement by inert gas. No additional cleaning, sterilization and air replacement, etc. is needed.
No, the inner bag of GPROKEG kegs is flushed during the production stage with 99.99% CO2 and vacuumed so that there is no air in the inner bag. The brewer can fill the beverage directly into the inner bag without any additional flushing.
As the beer is filled into the inner bag, the air in the keg is separated from the inner bag, the GPROKEG keg is filled while upside-up. It is possible to fill while it is upside down as well.
A vacuum check on the inner bag is needed to ensure the bag is intact and that there is no leakage of the bag. Check for any foreign matter inside the keg. Ensure the coupler and the spear are clean.
The head space is about 0.5L for all GPROKEG kegs.
We recommend 3 bar for filling pressure of CO2 and 2 bar for back pressure.
The depressurization process is quite simple. You only need to use the disassembly tool to connect with the keg's spear. This will release the pressure from the keg.
