Air Handling Units are crucial for Indoor climates. And the Indoor climates are deter­mining whether people feel good. Each person breathes about 15,000 liters of air every day. So it’s extremely impor­tant to ensure that air is prop­erly heated, cooled, humid­i­fied and dehu­mid­i­fied. Air handling units, or AHUs for short, make all of this possible. »

In order for a part to func­tion as a whole, parts that are damaged must be replaced. When a fan breaks down, it must be replaced: A retrofit, i.e. a fan replace­ment in venti­la­tion systems is neces­sary. »

Air exchange is absolutely neces­sary with insu­lating windows in order to regu­late air humidity. This is possible with central­ized and decen­tral­ized venti­la­tion systems.»

For a flow machine to be able to generate air flow, a fan needs a number of impor­tant compo­nents. No matter whether an axial, centrifugal, diag­onal, or tangen­tial impeller is used, the fan is driven by an elec­tric motor.»

A smart home collects digital data and connects your appli­ances and other elec­tronic devices with each other, so you can control them remotely. But the valu­able infor­ma­tion provided by the data has not yet been fully exploited!»

An old venti­la­tion system doesn't have to be replaced straight away. Often it can't be, because there's too little space or it costs too much. But how will a retrofit help solve these prob­lems?»

Predic­tive main­te­nance helps to ensure a long service life for fans. How exactly does this work, and how do you get the neces­sary data?»

Expanding cities need space to grow food. And that is exactly what is dwin­dling as the popu­la­tion grows. Could vertical farming be a solu­tion for this problem?»

Both direct current (DC) and alter­nating current (AC) describe types of current flow in a circuit. Both are essen­tial to enable the func­tioning of our elec­tronics, but do you know the differ­ence between direct current and alter­nating current?»

When you process a lot of data, you need data centers. But that much data can really make the system over­heat. It takes a lot of cooling and a lot of money to pay for it. So is there a cheaper, less energy-inten­sive way to keep your hot data cool?»

Due to climate change, elec­tro­mo­bility is becoming increas­ingly impor­tant, the number of elec­tric vehi­cles is also increasing rapidly. There­fore, it makes sense that the elec­tricity used for them should come from renew­able energy sources. But what kind of renew­able energy sources do we have and how impor­tant are wind power plants?»

When do instal­la­tion errors occur? And which para­me­ters should be consid­ered when installing fans? Here you will learn more about the instal­la­tion para­me­ters of fans and what to consider.»

A heat pump provides heat, but is also capable of cooling your home. It trans­fers heat from one place to another by different air or heat sources. Find out about the exact working prin­ciple of a heat pump here.»

Does a stepper motor or a servo motor suits the needs of your appli­ca­tion best? And what are exactly the differ­ences between a servo motor and a stepper motor? Lets find it out together.»

When space is limited, there is often no other solu­tion: A compact fan that takes up little space and still delivers the neces­sary perfor­mance is needed.»

Of course, plan­e­tary gears don't drive planets. It's called that because like in our solar system, every­thing revolves around the sun gear, the drive at the center.»

This video explains the working prin­ciple of brushed motors and brush­less motors.»

Mini­mize the wear, noise and energy consump­tion of your venti­la­tion system by using the FanGrid tech­nology.»

Reso­nance is key for a smoothly oper­ating fan. But, unfor­tu­nately, reso­nance can cause damage. That's how fans can handle reso­nance and vibra­tion.»

Under­standing the basic prin­ci­ples of air filter systems is key to develop better and more effi­cient ways to provide clean air. But how do you clean air? And what does clean air actu­ally mean? »

Does higher effi­ciency also mean better perfor­mance? Not neces­sarily. Ulti­mately, it depends on the appli­ca­tion and instal­la­tion loca­tion of axial and centrifugal fans.»

There are different motors and in this video we look at the differ­ence between internal and external rotor motors.»

Why does a fan need a frequency converter? Why is it impor­tant? And how does it work?»

When we compare an elec­tron­i­cally commu­tated motor with an elec­tric motor driven by an alter­nating current one thing becomes evident: The EC motor has a greater energy-saving poten­tial.»

What are the differ­ences between an elec­tric motor with an alter­nating current (AC motor) and an elec­tron­i­cally commu­tated EC motor and what are the advan­tages? »
