Optimized district heat production for cost-efficient operations

Valmet DNA District Heating Manager

Valmet DNA District Heating Manager is an Advanced Process Control application for the economical and operational optimization of heat production and delivery. The application considers all available online forecasts and information for optimal control of all units and conditions in the district heating system, including power plants, peak boilers, heat pumps, accumulators and other available units.

More autonomous and smart operations

With Valmet’s district heating network optimization solution, you ensure that your fleet has the best possible performance 24/7. The solution is an integrated part of the Valmet DNA DCS and new Valmet DNA User Interface, which enables best possible user experience for plant operators. As a multivariable closed-loop controller, Valmet DNA District Heating Manager supervises and regulates the whole network, ensuring that heat consumption and production are always in balance with the most economical fuel mix.

Used in conjunction with Valmet DNA Energy Management System, DNA District Heating Manager uses weather and district heat consumption forecast variations. It also takes into account changes in electricity and fuel markets. Additionally, the modular solution includes such advanced features as predictive supply temperature control, coordinated pressure difference control and static pressure optimization. This places less thermal stress on your network and extends your equipment’s lifespan.
