The new one-way keg owes its unique characteristics to an invention called the Double WallTM technology, which surrounds the bag containing the beverage.
Applying the Double WallTM technology has resulted in a cylinder inside a cylinder. Its two walls work together dynamically, giving the KeyKeg resistance to higher internal pressures and extreme low deformation at high pressures. Even soft drinks, stouts and other highly carbonated beverages can be filled in the new KeyKeg.
Like its predecessors, the KeyKeg20 houses a flexible multi-layered inner bag, which contains the beer, wine or soft drink. The content is dispensed by pressurizing the space between the bag and the ball. The beverage maintains best drinking conditions as it does not come into contact with the propellant gas when it is dispensed.
The new one-way kegs will be extremely resistant to external influences. They withstand very high temperatures during transport in hot climates and moisture has no effect on them. Being especially resistant to damage from outside, this KeyKeg is even safer to use. It is also good news for the environment: More than half (54%) of the KeyKeg¹s shell is made from recycled PET, while the grip consist of 100% recycled PP.
The cylindrical shape provides improved logistical qualities. Now 80 cylindrical KeyKeg20 units fit on one pallet. This shape combined with its low weight mean that 65% less transport is needed for the cylindrical KeyKeg compared to steel and other kegs.
The new design is an explicit reflection of its users’ needs. The new KeyKeg has an ergonomic grip, it is lightweight and extremely stable. It also takes up even less space than its predecessor and fits easily in existing cooling cabinets.
