Visitors to mountain village Kosh-Agach in the Altai Republic, part of southwestern Siberia, will be greeted with a unique panorama. Part of the view encompasses a nearby solar park with an area of 12,000 square meters. Before its operator can feed the power into the grid, inverters housed in white containers must convert the voltage. They need to operate reliably on hot days in the steppes, so air conditioners from Russian company Eurovent cool them. Three efficient RadiPac centrifugal fans from ebm-papst circulate air in each air conditioning system.
