The PR 7501 in the world’s largest solar heating plant

CO₂ neutral by 2030. That is the big goal of the municipality of Silkeborg in Denmark. And since opening the world’s largest solar heating plant this year, they will be able to reduce their annual emissions by approximately 15,700 tons.

In June 2017, the Danish utility company Silkeborg Forsyning and their contractor Arcon-Sunmark could celebrate the opening of the world’s largest solar heating plant. The project is moving the municipality of Silkeborg one step closer to being CO₂ neutral by 2030 – and PR electronics is proud to be a part of this with 36 units of the 7501 Field mounted HART temperature transmitter.


The new plant, which has been built in only seven months, has thermal collectors covering an area of approximately 156,700 m². It will produce 80,000 MWh per year – which will cover 20% of the annual need, when it comes to heating in Silkeborg. However, in the summer months the plant will produce enough heat to cover all heating needs in the area.

Designed for the harsh and hazardous environments often found in today’s process industries, the PR 7501 features a single compartment explosion-proof / flame-proof design with various mounting and thread options. Global compliance is assured through a full range of hazardous area and Marine approvals.




The PR 7501’s class-leading, high-definition display features a 5-digit read-out, radial bar graph and process/diagnostic related text. This is further enhanced by an energy-efficient backlight, which can be white or red, and even flash on error conditions. Ease of use is further enhanced by the unique patent-pending local operator interface.
