Maximizing efficiency with eWON

As natural resources are getting scarcer, it is increasingly important to get the most out of the energy sources we have. Using combined heat and power units is a smart way to optimize the use of energy and get both heat and power from the same generator. In Lollar, Germany, Bosch KWK Systems develops state-of-the-art heat and power units enabling their customer to become more energy-efficient. But as all advanced machinery, Bosch's heat and power units need maintenance every once in a while. With eWON remote routers, Bosch found a way to do this remotely.
With eWON, small adjustments can now be done from our centre with a few mouse clicks.


Bosch's combined heat and power units obtain what is possible from natural gas, sewer gas, or biogas. And the output is impressive. BOSCH KWK's systems range between 12 kW to more than 2 Megawatts of electricity and produce enough heat to supply an entire district.

One of Bosch's trademarks is compact construction. In the tradition of German engineering, every centimeter counts. This enables the plants to be easily accommodated in buildings and it also facilitates transport. This is apparently a good concept, as demand is rapidly increasing.

But as more systems are being deployed, Bosch also needs to face an increasing need for maintenance. "The more systems that are running, the higher the expense in service an maintenance, so we wanted to find a way to do this remotely", says Yassin Ouchen of Bosch KWK. "Our main objective was to find a way to do software updates remotely at any time. However, many of our units are located out in the sticks, where there is normally no broadband connection."

Therefore, Bosch looked for solution which could communicate via the cellular network.

How it works

By using eWON routers, Bosch can provide their customers with quick remedies to any questions or errors. if a customer calls, a skilled engineer can immediately log in to the relevant system and see what can be done.

Preventive maintenance is also possible, as Bosch can get notifications whenever operation hours or other parameters reach certain levels, or when machines exceed their service time. Statistics and analytics are made possible as control system logs, Modbus logs etc. are read into the eWON routers.
