SMART IN FLOW CONTROL. Benefit from our expertise

An essential contribution to climate protection and the sustainable use of resources is made by exploiting the potential of cogeneration, i.e. using the waste heat produced during electricity generation. While geothermal and solar thermal systems as well as industrial waste heat feed more and more heat into district heating networks, ambient air cooling or absorption plants that convert heat into cold generate environmentally friendly cooling. The supply of district heating is scheduled for considerable expansion to achieve the climate protection objectives set for 2020 by the EU.

9 Self-operated regulator technology

Self-operated regulators by SAMSON have been used in district heating systems for many years. Their tasks include controlling, monitoring, or limiting variable parameters as well as compensat- ing fluctuations in network pressure or differential pressure that occur in transfer stations. All in all, the regulators ensure the safe operation of district heating and cooling networks.

After an initial fault analysis and possibly changeover to manual mode, concise instructions can be passed on to qualified personnel to enable them to find the problem quickly.

16 Remote maintenance Remote maintenance does not just involve supporting our customers with informative plant schemes. It also allows the remote operation of controllers in the manual mode, for example to change time sched- ules or load and save controller configurations. Naturally, all these topics are explained in the associated documentation.

Accessibility The web site can be accessed from anywhere at any time by computer, smartphone, or tablet computer. No special app is needed. A conventional web browser is all it takes, regardless of the operating system.
