Keravan Energia adopted Ewon gateways and routers for reliable connectivity
Keravan Energia enhances competitiveness through continuous development and automation of energy production and transport. To unify diverse automation devices across its heating plants, Keravan Energia adopted Ewon (HMS Networks) gateways and routers, ensuring secure, flexible, and cost-effective data transmission via public networks, with high cyber security measures.
Kerava is a city in southern Finland with a population of more than 38 000 people. Keravan Energia provides comprehensive energy supply in the region. It annually sells 400 GWh of electricity, 400 GWh of heat and process steam, and 25 GWh of gas.
To stay competitive in the energy market, Keravan Energia continuously develops and automates the production and transport of energy resources.
Goal: Integration of Automation Devices into one system
As the communication interface with its stations, Keravan Energia chose the Ewon (HMS Networks) gateways and routers. Using standard Ewon products, Keravan Energia quickly developed and tested a budget experimental project, which facilitated the rapid decision in favor of Ewon.
In the Kerava region, there are several automatic heating plants managed from the main control room. These are stations of different types, and they use automation devices from different manufacturers.
Klinkmann’s goal was to bring all these diverse stations under unified management. Previously, modems from different manufacturers were used with varying success, resulting in many difficult-to-manage devices.
Within the selected concept, remote units are connected to the central unit via a wired Ethernet network and mobile network connection. All data transmission connections are based on the use of public networks, where connections are protected using strict cyber security measures.
Advantages of Data transmission using Ewon gateways:
- Unified data exchange with automation devices from different manufacturers, one solution for all
- Flexible use of public data networks allows for the best data transmission mode for each subscriber and optimizes transmission costs
- The structure can be easily replicated and used to connect new stations
- Ease of system maintenance due to the uniformity of equipment
