Solar heating plant reduces CO2 emissions by 15,700 tonnes annually

The world’s largest solar heating plant in Silkeborg, Denmark harnesses energy to heat the homes and workplaces of 40,000 citizens. It supplies 18-20% of the annual heat consumption in the city of Silkeborg, Denmark, which has an ambitious target of CO2 neutrality in heat production by the year 2030.

The solar hot water system runs on SONDEX® heat exchangers and VLT® drives, which have powered a 30% cost reduction in its first year of operation, compared with traditional drive systems.

The VLT® AQUA Drive has proven a successful solution for this application. Project Manager, Per Hvilshøj Christiansen, explains: “What we have experienced with Danfoss Drives is that the drives are very energy-efficient with minimal operating costs. Add to this, the life expectancy and the level of technical support you are able to get anytime, this has proven a great success for all parties involved”
