Frese­nius Kabi is working on its climate foot­print. Part of these efforts is a retrofit at the Uppsala site with more than 150 fans being replaced. This will deliver energy savings of 30 percent per year for the company. Thanks to the redun­dancy of the FanGrid solu­tion, the company no longer has to fear stop­pages costing hundreds of thou­sands of euros.»

In a care­fully planned and opti­mally prepared campaign, the leading Swiss dairy processor Emmi at its Suhr site, is replacing AC fans on 69 coolers with modern EC vari­ants, while they are still in oper­a­tion. Project manager Matthias Künzli is now delighted with the huge energy savings – and much more.»

Vertical indoor farming is consid­ered a promising future concept with numerous advan­tages. In partic­ular, the yield per unit of area is signif­i­cantly higher than in conven­tional agri­cul­ture, as the systems are oper­ated all year round. Fans, drives and automa­tion solu­tions play an impor­tant role in ensuring that the plants always have ideal condi­tions for growth.»

The venti­lation system in the speed skating rink at Berlin’s Sport­forum sports complex still used old belt-driven fans. They consumed a lot of elec­tricity, made a lot of noise and if they failed, the entire system came to a stand­still. High time for an upgrade to effi­cient RadiPac fans.»

Completely replacing old venti­lation systems is time-consuming and costly. The retrofit project at a large furni­ture store in Dubai shows that there is a better solu­tion: EC fans in the form of a FanGrid and demand-based control.»

Vilpe Sense from Finnish company Vilpe detects water damage in roofs before it occurs. The system dissi­pates excess mois­ture to the outside, by using an EC centrifugal fan from ebm-papst.»

In building tech­nology, demand for decen­tral­ized resi­den­tial venti­lation systems is increasing with growing envi­ron­mental protec­tion and energy effi­ciency require­ments. The devices installed in the façade are not only suit­able for reno­va­tion work, but are also gaining impor­tance in new build­ings. For push-pull appli­ca­tions, there are now new, energy-effi­­cient fans that impress with their high effi­ciency, pleasant oper­ating noise and compact dimen­sions.»

In the fight against climate change, Swiss company Clime­works is filtering a large amount of carbon dioxide from Iceland’s air with the “Orca” CO₂ suction unit and conveying it into the ground.»

The AxiRev 126 is the new stan­dard for effi­cient push-pull appli­ca­tions in resi­den­tial venti­lation. Tobias Sieger, respon­sible for the venti­lation design and flow simu­la­tion, explains how the reversing fan achieves this.»

According to the so-called F-Gas Regu­la­tion, emis­sions of fluo­ri­nated green­house gases (F-gases) in the EU are to be signif­i­cantly reduced by 2030. It is there­fore essen­tial to switch to natural refrig­er­ants with a low global warming poten­tial (GWP). However, these are often flam­mable. This means that all compo­nents installed in heat pumps, for example, must meet the stan­dards for flam­mable refrig­er­ants. This also applies to the fans used, but these also need to be as quiet and energy-effi­­cient as possible.»

To protect his employees, Michael Braun of the Beck­stein wine­growers’ coop­er­a­tive replaced his old venti­lation system with a new one. The system reli­ably draws dangerous fermen­ta­tion gases outside, while also creating more room and peace for wine produc­tion.»

If there is one thing a super­market does not need, it is reno­va­tion work taking place during the most impor­tant shop­ping season. So it is a relief that ebm-papst found an uncon­ven­tional solu­tion for the cold water system of a South African hyper­market in collab­o­ra­tion with HCM, a refrig­er­a­tion and air condi­tioning company.»

Walter Roller GmbH & Co. began to system­at­i­cally convert their refrig­er­a­tion and air-condi­­tioning equip­ment over to EC tech­nology as early as 2011. Pioneers CEO Wolf­gang Krenn and Product Manager Andreas Binder discuss what drives them, how their customers have reacted, and the role that EC plays for them today.»

Modern agri­cul­ture is unthink­able without green­houses. They make it possible to harvest inde­pen­dently of the seasons. But plants only thrive in them when the air supply and distri­b­u­tion are perfectly regu­lated. AxiCool fans from ebm-papst are ideal for this task.»

Ralf Mühleck, Team Leader, Commer­cial Venti­lation, is an expert in retro­fitted fans at ebm-papst and always knows the right product for any project.»

Bottling and pack­aging specialist Krones now also offers cooling towers perfectly tailored to its systems. One of the first to benefit from the custom, cost-effec­­tive, and effi­cient solu­tion is the bottling giant Refresco.»

To keep pota­toes deli­cious for a long time, they have to be stored at a constant three degrees Celsius. Stocke Gård Farm relies on a sophis­ti­cated venti­lation system for this.»

Deciding which fan is the most effi­cient, and works at the maximum energy effi­ciency, is not that simple: Fans are complex flow machines that react to every change, including instal­la­tion condi­tions, speed vari­a­tions or pres­sure ratio changes due to filter cont­a­m­i­na­tion. As a result, no fan works at the “best effi­ciency” at all times and in all places. Having said that, centrifugal fans are the better choice for most appli­ca­tions in AHUs.»

Axial fans have to meet high demands on venti­lation and air-condi­­tioning equip­ment, because the cold side of the cooling circuit is subject to harsh envi­ron­mental condi­tions. Against this back­ground, ebm-papst has devel­oped a new axial fan series in which AC vari­ants also meet the future ErP require­ments.»
