The history

of Brunata

The Danes were the first in the world to use heat cost allocators, and the credit for this can primarily be claimed by Brunata. The whole story started with an engineer by the name of Constantin Brun, who was interested in how to allocate heat costs fairly and accurately – at the same time making it possible to save energy.

At his engineering firm, he developed a whole new type of heat meter that allowed accurate measurement and allocation of heating costs in properties. The family-owned Danish company Constantin Brun was thus born. And it marked the start of a century of technological milestones in the measurement and allocation of heat, water and energy.

Brun meets ATA

One of the milestones was the merger with the Swiss company ATA in 1950. The change of name to Brunata lay ahead, as did an intense technological development phase in which more and more types of consumption meters were developed. Water meters amongst others, which were widely used in the 1970s. But as always, engineering was key, and for example, Brunata’s heat meters included patented technology that still makes them the most accurate on the market.

With the proliferation of the internet, Brunata naturally went online and offered remotely read meters as well as completely new and efficient ways of delivering data to provide customers with the best possible overview.

The intelligent future

At Brunata, development never stops. In 2018, Brunata was acquired by the German company Minol, a global frontrunner in energy, measurement technology and data networks. With new knowledge and technology behind it, Brunata will in future take the lead in the Internet of Things and the move towards smart buildings and smart cities.

This new phase has only just begun and it is the one that will successfully take Brunata into a new century. With curiosity and engineering as the driving force. And with the constant goal of saving time, effort and energy resources for society and for the individual citizen. Totally in the spirit of Constantin Brun.
