Mosbaek A/S was founded in 1969, when inventor and civil engineer Jørgen Mosbæk Johannessen was the first person in the world to invent a flow regulator. This device for sewer systems released only a limited water volume even though it had a large orifice opening. Jørgen decided to call his invention a flow regulator.
The first idea for a flow regulator emerged as early as 1959 when Jørgen Mosbæk Johannessen, in the first year studying for a degree in engineering at Horsens Technical School, was given an assignment with developing a complete drainage project for a single-family house.
At home, his mother collected rainwater in a large tub and used the soft water to rinse clothes. This gave Jørgen an idea that it should be possible to collect rainwater from the single-family house's roof in a inspection chamber/structure and then use an attenuation device to slowly release water into the main pipe out in the street. This way, the municipality could suffice with main pipes that had far smaller dimensions: in other words, a set-up like this could save money. But the set-up had to be invented first.
In the following years, Jørgen graduated in 1961 and subsequently worked for various consulting engineering firms as a project engineer in the drainage sector. Here, too, he often saw a need for a set-up that could attenuate rainwater and prevent flooding. Therefore, he never abandoned his flow regulator idea and spent his leisure time diligently experimenting with various flow regulators, either as experimental models in the kitchen sink or in a cistern in his back yard.
He discovered that the best, most compact way to design a flow regulator was to use a round container which caused the water to rotate as it flowed through. This substantially slowed down the water flow. The design reminded of what is now called a centrifugal flow regulator.
For years, Mosbaek A/S has been working to document its products' performance, dependability and quality. This has now culminated in the acquisition of an ETA, based on previous efforts involving the European Technology Verification programme which now allow CEV flow regulators to be CE marked.
