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.»

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.»

Fans used in venti­lation, refrig­er­a­tion and air condi­tioning systems or other indus­trial appli­ca­tions are gener­ally subjected to rigorous testing. But in prac­tice, fail­ures often occur after a short time. The cause is usually vibra­tions resulting from the way the fans are installed. The reso­nance char­ac­ter­is­tics of a fan must there­fore be tested during oper­a­tion and in inter­ac­tion with the surround­ings in order to take measures if neces­sary.»

Many drivers of elec­tric vehi­cles dream of charging their batteries rapidly and getting back on the road. Thanks to its cooling system for charging stations with battery storage systems, West­phalian company tech­no­trans is helping to make this dream a reality.

Fans are flow machines. Fans opti­mized according to aero­dy­namic criteria reli­ably deliver the desired air flows at the rele­vant oper­ating point and are energy-effi­­cient and quiet in oper­a­tion. But the instal­la­tion situ­a­tion also plays an impor­tant role. A fan installed in the appli­ca­tion is often not as quiet as hoped or less effi­cient than the spec­i­fi­ca­tions in the data sheet, because inter­ac­tions between the fan and the customer device have an impact on the flow vari­ables. Simu­la­tion can help here. the behavior of a fan in the specific appli­ca­tion can be precisely calcu­lated and visu­al­ized with CFD (Compu­ta­tional Fluid Dynamics, i.e. numer­ical fluid mechanics).»

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.»
