PrevOffices and Shops Ventilation for Volta 1 Renovation in Tallinn, EstoniaThe Volta 1 building was renovated in 2021, and the challenges were that there were not enough energy sources (non-electric and non-heating energy) and no space inside the building. All units are built on the roof and have integrated heat pumps with reversible solutions. By cooling in the summer and heating in the winter with a single heat pump system, efficiency is secured by the smart algorithm that avoids defrosting and uses bypass systems to work against each other. Total air volume: 40 000 m³/h Smallest air volume: 1.100 m³/h Highest air volume: 20.500 m³/h Serie: SKWNextEfficient Industrial Ventilation for Tartu Mill factory, EstoniaPowder mill production process air is taken through our RunAround systems, which recover energy for the supply air. The air from powder mill production is humid, dusty, and highly corrosive. That is handled with our C4 corrosive resistance composite casing. Units are all on roof top o the production building on height of 30m. Number of units: 4. Air Volume: 216.000 m³. Largest air volume: 72 000 m³. Smallest air volume: 36 000. m³. Serie: 2xSKW8.7, 2xSKW8.6. Type: Rooftop units
