Calculation programs

Our goal is to support you in your everyday work as effectively as possible. With the help of our calculation programs, you can size every available product online.

Air Volume Flow Calculator

With our air volume flow calculator, you can determine the required outdoor air volume flows in accordance with EN 16798 in just a few seconds – for individual rooms, entire floors or complete buildings. Enter the room dimensions and the total number of people, and automatically receive the fresh air flow, broken down into building-related and person-related shares, as well as the resulting air change rate.

NC- and NR-Level Calculator

With our NC‑NR tool, you can quickly and precisely determine the room acoustic assessment of technical units based on the sound power level. Enter the unit’s sound data as well as the room dimensions and room type, and automatically receive a chart showing which Noise Rating (NR level) or Noise Criteria (NC level) is achieved.
