The Feld­schlöss­chen brewery is a land­mark in Rhein­felden, with its striking archi­tec­ture and nation­ally renowned beer. It was founded in 1876 by Theophil Roniger and Mathias Wüthrich and built in the “castle renais­sance” style. This was intended to give the company a digni­fied, pres­ti­gious appear­ance that honored the old brewing tradi­tion. At the same time, Feld­schlöss­chen was often ahead of its time. As early as 1889, it had a railway siding connec­tion so that beer could be deliv­ered nation­wide. From 1912 onwards, the brewery horses were replaced by trucks – and today, elec­tric trucks, powered by their own solar energy, deliver the beer in a CO₂-neutral way.

The brewing process itself is also modern. Highly auto­mated brewing systems digi­tally control the mashing and fermen­ta­tion, combining tradi­tional brewing artistry with the latest tech­nolo­gies. Another example of the inno­v­a­tive approach is the retro­fitting of a venti­lation system with RadiFit EC fans from ebm-papst.

RadiFit: Uncom­pli­cated and effec­tive

When the venti­lation in one of the employee changing rooms at Feld­schlöss­chen stopped working – the impeller of the respec­tive AC fan had broken off from its mounting after count­less years of oper­a­tion – a rapid main­te­nance measure was required. The chal­lenge was met by installing the old fan in a large monoblock system. Sebas­tian Haude, Util­i­ties Manager at Feld­schlöss­chen Supply Company AG, explains: “From a busi­ness perspec­tive, installing a new monoblock was out of the ques­tion – it would have cost around 30,000 Swiss francs.” The tech­nical depart­ment turned to R. Haesler AG, with whom they have worked closely for some time now.

More effi­ciency, less costs: Retrofit

Retrofit of fans with ebm-papst

Retro­fitting existing fans in venti­lation and cooling systems with effi­cient EC fans and demand-based oper­a­tion can save up to 60 % energy and costs – and protect the envi­ron­ment at the same time.

More effi­ciency, less costs: Retro­fitting fans with ebm-papst

Haesler is a leading provider of energy-effi­cient and envi­ron­men­tally friendly solu­tions for heating, venti­lation and alter­na­tive ener­gies. Timo Rünzi, venti­lation project manager, was tasked with looking for a signif­i­cantly cheaper and, above all, uncom­pli­cated solu­tion to the problem for his customer. “Fatlum Korbi from ebm-papst had recently presented the RadiFit to us for precisely these kinds of projects using monoblock systems,” he says, “so I contacted him directly.” Rünzi and Korbi inspected the system together on site at Feld­schlöss­chen. “The current instal­la­tion situ­a­tion was extremely tight and cramped. Being mini­mally inva­sive and highly effec­tive, the RadiFit was the only solu­tion.”

Fatlum Korbi took care of the fan design, providing Rünzi with the data sheets and a few sample pictures from previous retro­fits – and then it was time to get started. Timo Rünzi explains: “Our service tech­ni­cian removed the broken fan and installed and commis­sioned the RadiFit within a few hours.” The compact design and plug-and-play construc­tion helped, and no modi­fi­ca­tions to the old monoblock system were neces­sary. Although energy savings were not the focus of the retrofit, the effi­ciency and high oper­a­tional reli­a­bility were compelling. Sebas­tian Haude is well satis­fied with the result: “The retrofit cost only a frac­tion of a new system and will quickly pay for itself.”
