What does retrofit in Air Technology mean? Retrofit refers to the retrofitting or modernization of existing technical systems with the aim of improving their performance, efficiency or functionality. In Air Technology, this typically means replacing old, sometimes belt-driven and therefore maintenance-intensive AC fans with highly efficient, maintenance-free EC fans with integrated control electronics, optimized air […]

For some time now, motor and fan specialist ebm-papst has been employing a continuous improvement process in fan technology. In recent years, the centrifugal fans in the RadiPac series specially designed for use in air conditioning and ventilation units have been constantly optimized, with particular emphasis on energy efficiency, noise reduction, and handling. With the […]

Contents Tracking down sound sources in fans is not an easy task. Whereas relatively advanced aerodynamic simulation programs are now available and have become established on the market, the simulation of aeroacoustics is still very much at the research stage. The number of cells needed for the required spatial resolution of small turbulent structures is […]

Many applications require high air performance. Data centers, large industrial building complexes, hotels, residential complexes and hospitals are all typical examples. Replacing one large fan in central air conditioning systems with FanGrids containing several smaller fans that function in parallel provides many benefits in practice. Smaller, more lightweight and simply better In this way, the […]

The world badly needs energy-saving solutions; from lighting right through to electrical drive systems. Even simply adapting the speed of drive systems to the actual torque/power requirements saves on unnecessary power consumption. The use of efficient EC motors also taps into additional potential for savings, which benefits the environment and the operator’s running costs in […]

Cleanrooms have particular requirements when it comes to their ventilation systems. These requirements include sufficient air throughput and pressure, precise control of temperature and humidity, as well as a constant air purity achieved by filtering out even the smallest impurities. Filter-fan-units (FFU) designed for ceiling installation combine filter technology and state-of-the-art fans, enabling them to […]

St. Franziskus-Stiftung Münster, a foundation that is one of the largest denominational hospital groups in Germany, has 18 hospitals and ten facilities for the disabled and elderly. Running this many facilities entails a huge amount of energy consumption at a time when cost pressure is increasing throughout the industry. The air handling units (AHUs) in […]

There is demand for efficient and, most importantly, quiet air/water heat pump systems suitable for indoor, outdoor or hybrid use, which use natural refrigerants and whose output can be intelligently adapted to the actual conditions. This requires fans that not only operate economically at optimum efficiency and pleasant noise levels, but can also communicate and […]

A typical working day in the office often starts by pressing the on button of a computer. The screen lights up, the latest e-mails are loaded and the calendar displays what is coming up that day. In the background, thousands of gigabytes of data are passing unnoticed through Microsoft’s German data centers. Since April 2024, […]

Vibration is omnipresent. While some kinds of vibration are perceived as pleasant, such as music, others can cause major damage. This is because resonance may occur if a system is excited periodically by a force whose excitation frequency matches a natural frequency of the system. In this state, vibration amplitudes increase sharply. Although the attenuation […]
