SAM DISTRICT ENERGY AT A GLANCE

SAM DISTRICT ENERGY is a web-based solution for managing, controlling and optimizing heating
and cooling systems. All key data on connected controllers, utility meters, PLCs and electric actuators
are saved at one central location.
Our gateways enable you to easily digitalize your heat supply and interact with the connected
devices using SAM DISTRICT ENERGY using a wireless connection.
An ideal solution for upgrading existing systems

Analysis of consumption data

Our customers have been using SAM
DISTRICT ENERGY in numerous different
applications for several years.
Automated management of controller backups

Customized plant schemes

Intuitive adaptation of heating characteristics

SAM DISTRICT ENERGY enables you to optimize and monitor your heat supply using
clearly structured, professional interfaces.
For example, you can do the following:– Automatically generate comparative invoices for different buildings (benchmarks) and further reports– Remotely adjust heating characteristics on cold days
– Coordinate service calls– Set up different user levels to allow customers to access their systems– Monitor different types of heat generators by different manufacturers, such as combined heat and power plants,
wood pellet burners– Manage decentralized buffer storage units to ensure an efficient use of resources– Generate and send alarm notifications depending on customized thresholds– Exchange data over cross-traffic without requiring complicated wiring– Set up automated management of controller backups

Controlling the Hydraulic Worst Case from the Cloud
Local heat supply network operated by an energy supplier association(Energiegenossenschaft Emstal) in Lathen, northern Germany
The local heat supply network of the community of Lathen in northern Germany includes a cloud-based control of
the hydraulic worst case using the web-based SAM DISTRICT ENERGY asset management tool and SAM MOBILE
gateways for mobile phone networks. For this control function, the differential pressure measured at certain stations
is sent to the web portal. The resulting signals to control the network pumps are generated by algorithms in the web
portal and sent to the heating stations.
A fixed differential pressure is used upon failure of the control signals. Clear benefits of this solution include quick
installation of the gateways, easiness of implementation and a high level of IT security. In addition, measuring points
can be distributed all across the entire network as desired.
The web portal makes it possible to simply add further functions and applications to the existing control features.

Benefits for plant operators– Minimized energy consumption by reducing the pump output– Reduced flow-induced noise and less stress on the components installed– Remote monitoring of differential pressure, temperature, heat meters and district heatingcontrollers– Trouble-free scaling of the system on extending the district heating network– No wiring from the energy generation to the energy consumers required

10Distributed solar thermal energy fed into heat networks
District heating network operated by Düsseldorf municipal services company
Whether in local heat supply and district energy networks or heat communities, solar thermal energy fed into heat
networks has already contributed significantly to implementing low-emission heat supply in the short and medium
term. Strict requirements are placed on the systems engineering in this case since solar heat as an energy source canonly be controlled to a certain extent. We took on the challenge and worked together with the Düsseldorf municipal
service company and the Steinbeis research institute to find an efficient and economic overall solution for a reliable
heat supply. SAMSON supports the project with engineering expertise and components from our range of systems
and valve engineering.

Active climate protection– Decarbonization of district energy networks even in urban areas– Use of unused rooftops– Integration into existing network infrastructures– Return temperature of the district energy network raised to the level of the supply temperature

Successful field study– 232 m² collector area installed on an unused rooftop– Annual solar yield: approx. 350 to 500 kWh/m²11
