An efficient way to use energy
The expansion of district heating continues apace, and for a good reason: The district heating generated by combined heat and power in cogeneration plants has a high level of efficiency and therefore allows provision of heat and hot water with particularly sparing use of resources.
The precondition: reliable process information
To be able to ensure optimal operation of the cogeneration plants and security of supply, the control centre needs information about flow and return temperatures, pressures and flow rates, circulation quantities and thermal output.
SAE offers powerful convenient solutions, which are already used in numerous district heating networks in German cities, including Berlin, Hamburg, Cologne, Mannheim and Aachen.

A tried-and-tested solution: the net-line FW-50
A typical example of our expertise in the field of district heating is the monitoring of district heating lines with the aid of the net-line FW-50 telecontrol system. To achieve a sufficient differential pressure at the point of minimum differential pressure, the flow pumps are regulated along the lines. Relevant parameters in this connection are the agreed pressure levels, the set point of the control centre and return regulation. If required, visualisation and control can also be carried out on site by connecting touch screens.
