PrevEfficient Normal Ventilation for Pühajärve SPA & Resort Renovation in Otepää, EstoniaRenovation project where the existing unit was to be removed and a new unit with an integrated compressor for cooling was to be installed by using normal doors. As well the unit is designed to be fitted in narrow room height. The first SKAWEN unit was built as a prototype and delivered to the customer. The unit is continuously ventilating with heat recovery all year long, heating in winter and cooling in summer. Number of units: 1 Air volume: 3.800 m³/h Serie: SKW protoype Build art: In ventilation chamber.NextAdvanced Biogas Plant Engine Cooling Project in Rhadereistedt, GermanyThis project involves two supply and exhaust air units for two CHP engines. These are located in a specially separated building on the site of a biogas plant. The challenge in this project was, on the one hand, that both units have to convey the combustion air of both engines and, on the other hand, that the radiant heat of the engines and generators has to be removed via the extract air. The supply air volume is increased to the same extent so that there is no difference in air pressure in the room compared to the ambient pressure. In addition, the units were integrated into the fire protection concept by mapping various fire and explosion protection measures. Number of units: 2. Total air volume: 128.000 m³. Biggest single air : 44.600 m³ volume. Smallest single air: 19.400 m³ volume. Series/ Line: SKW6.4 + 8.4 & SKW7.7 + 8.7. Outdoor installation: 2 of 2. Flatpack: no. Special features: 2 outside units.
