Acute skilled labour shortage
Conventional event bars need 6–7 staff per station. Austrian hospitality has more than 50,000 open positions (WKO 2024). Events fail for lack of personnel, with no structural end in sight.
Sustainable
Beverage Solution
A solar-powered, automated bar in a container. It serves festivals and events with 100% green energy, no water connection and no high-voltage supply.
3 unsolved problems in the events industry
Efficiency at its limit
Long queues, manual processes, poor cooling and up to 15% beverage loss. Organisers lose revenue for every minute guests wait in line.
Sustainability needs data
Sponsors, tenders and authorities ask organisers for proof of sustainability. The foundation is missing: real-time monitoring of consumption, waste and emissions during the event.
Solution
-
Rapid, automated dispensing
Automatic dispensers pour a perfectly chilled 0.5 l beverage in 6 seconds. Shorter queues, a smoother experience for every guest.
-
100% powered by green energy
Solar panels on the roof power every system on board. No fossil fuels: lower carbon emissions and lower operating costs.
-
Consistent cooling, premium quality
Highly insulated 500-litre tanks keep the temperature steady, so the last pour is as good as the first, even at outdoor events.
-
Remote real-time monitoring
Organisers see live data on temperature, energy use and revenue. Full transparency and control, fewer handling errors, clear accountability.
-
Easy installation and delivery
The container is self-sufficient: no water supply, no high voltage. Simple logistics, deployment anywhere and quick integration into any festival site.
