Compact fans and fans with a long duty cycle are oper­ated in refrig­er­ated display cases, refrig­er­ated cabi­nets and bottle coolers in super­mar­kets, as well as in large cold storage facil­i­ties. EC fans with their high effi­ciency levels are becoming increas­ingly popular in this field, not least because of rising energy costs. Intel­li­gent networking options can also simplify service and main­te­nance.»

Contin­uous cooling or freezing of goods in super­mar­kets’ sales and storage areas is essen­tial for quality assur­ance. Fans play a central role here. Along­side them having the lowest possible energy consump­tion, reli­a­bility is the main focus here. If a fan fails, it is impor­tant to locate and rectify the fault quickly to prevent the cold chain being inter­rupted. Fans with intel­li­gent EC-motors provide impor­tant infor­ma­tion via the MODBUS RTU inter­face.»

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 Korea’s Smart Farm Inno­va­tion Valley, toma­toes, straw­ber­ries and the like grow almost by them­selves thanks to intel­li­gent tech­nolo­gies. Fan coil units from Dowoo ENE with axial fans from ebm-papst ensure the perfect temper­a­ture.»

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.»

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.»

Centrifugal fans from ebm-papst set new stan­dards: Thanks to aero­dy­namic opti­miza­tions, inno­v­a­tive mate­rials, sophis­ti­cated design details, and highly effi­cient EC motors with intel­li­gent control elec­tronics, they not only deliver signif­i­cantly more air perfor­mance than before, but they are also partic­u­larly quiet and effi­cient.»

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.»

The Ster­isafe Pro robot system elim­i­nates 99.99 percent of all viruses, bacteria and fungi, and runs on just water and elec­tricity. It uses ozone to disin­fect rooms and surfaces, which can find its way into extremely small gaps and crevices with the use of effi­cient fans.»

In a Danish distillery, it was not only the whisky that reached maximum temper­a­ture in the summer. The subse­quent instal­la­tion of two fans brought cooling for visi­tors and employees.»

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.»

The venti­la­tion system in the Australian Birk­dale Shop­ping Center was nearing end of life. So what do you do to continue to make the purchasing expe­ri­ence of approx­i­mately 2,000 customers per day pleasant? An upgrade was required!»

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.»

To achieve high air perfor­mance in venti­la­tion tech­nology, large, single fans are no longer today’s preferred solu­tion. Instead, we recom­mend FanGrids: several smaller fans combined to work together in parallel.»

A lot has happened in fan tech­nology. Aero­dy­nam­i­cally opti­mized EC fans are becoming estab­lished in refrig­er­a­tion and air condi­tioning appli­ca­tions. Never­the­less, there is still scope for further opti­miza­tion in noise cancelling. Thor­ough acoustic testing is carried out to iden­tify each indi­vidual sound source, also taking the instal­la­tion situ­a­tion into account.»

For effec­tive and effi­cient home venti­la­tion, it must be possible to precisely regu­late the air flow in order to prevent over­pres­sure and under­pres­sure in the resi­den­tial building. There are even more advan­tages for users if the fans are also able to process signals from external sensors.»

Zeppelin Power Systems adapted the air intake systems in its gas plant – and now manages with less than five percent of the orig­inal power.»

At the end of each shift, employees in Europe’s largest pig slaugh­ter­house scrub the work areas until they are spick-and-span. Thanks to an upgraded venti­la­tion system, work can now resume faster after cleaning has finished, and the oper­ator also consumes far less energy in the process.»
