Rotating Chimney Cap

Ohnsorg’s Patented Rotating Chimneys: Precision Meets Performance

In the world of chimney solutions, the rotating chimneys by Ohnsorg stand out, thanks to our patented axis design. This innovative approach ensures that our chimneys have an impressively low response threshold, reacting to wind speeds as minimal as 1 m/s. Such sensitivity ensures that even the slightest breeze can set the chimney cap in motion, aligning it perfectly with the wind’s direction.

But what makes our rotating chimneys truly exceptional? It’s the precision with which they operate. When the chimney cap turns, it does so with the accuracy and responsiveness of a weather station’s wind direction sensor. This level of precision ensures optimal airflow, enhancing the efficiency of the entire ventilation system.

Installation Precision is Key

While our rotating chimneys are designed for optimal performance, their efficiency is closely tied to the accuracy of their installation. It’s crucial that the rotating chimney cap is mounted perfectly vertically. Any deviation from this can impact its performance. Therefore, always use a spirit level during installation to ensure the chimney cap is aligned correctly. A perfectly vertical mounting guarantees the excellent rotating properties that our chimneys are renowned for.
