3 unsolved problems in the events industry

Beverage dispenser taps Guests queuing at a bar counter

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.

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.
