The biggest challenge was the fully automatic 650m² and 20 meter high warehouse. It houses 24,000 boxes, each with up to 24 bottles, before they are delivered. Clemens Sadnik said: "In our automatic warehouse, a constant temperature of 18 degrees Celsius must prevail all year round, as the stored wines and spirits react very sensitively."

In order to meet the various requirements outside the automatic warehouse – be it in terms of temperatures or operating times – the area is divided into six control zones. These are heated by 22 needs-based adjustable TopVent TH units in combination with the UltraGas condensing boiler from Hoval. Christoph Steinhäusler explains: "The hall air conditioners and the gas condensing boiler are perfectly matched to each other and run at a very low system temperature, which further increases the efficiency of the heating."

The installation of the tailor-made hall air conditioning system for Del Fabro Kolarik was carried out in cooperation with Hoval's partner Licht Loidl. "Thanks to the close cooperation of all participants, we managed to place the heating and ventilation centre in the middle of the building. As a result, we were able to massively save on cable lengths and thus on costs," said Mr. Sadnik. Accepting challenges and finding innovative solutions is the basis for successful cooperation.
