The Neukölln AG district heating plant is the local heat supplier for Berlin-Neukölln and supplies around 40,000 households with district heating. In the renovation of the work, Vattenfall Europe Wärme AG also fundamentally renovated the existing heat store.

The client wanted a unique lighting solution, which showed the temperature states inside the 22 meter high heat storage.

Once again we were able to convert creativity and well-founded know-how from electrical engineering into an ideal solution. A 20 m high light column was specially developed, which was installed on the outside of the hot water tank. The challenges were to construct the column so that it can be securely attached, is windproof and weather -resistant. In addition, it had to be able to defy the heat radiation of the memory. The LED technique used should radiate rotation-symmetrically and the respective light colors should be clearly visible even in sunny lighting conditions.

A PT100 resistance thermometer with platinum sensor elements was used, which change their electrical resistance depending on the temperature. With special control and switching electronics using DMX, a digital tax protocol from stage technology, color changes are also generated. The finished light column thus shows four color gradients, with each color standing for a different temperature rang.

The result enthusiastic -with a look, the technician is informed about the processes in the heat storage system without having to go to the tax station.
