Wädi-Brau-Huus AG, a small traditional Swiss brewery in the canton of Zurich, produces beers with great care using only raw materials from guaranteed organic cultivation. In doing so, the company dispenses with now common cellar treatment methods such as the acceleration of fermentation processes, pasteurisation or flash pasteurisation and achieves an annual output of around 2,200 hectolitres.
The brewery obtains hops and malt either from Swiss organic producers or from Germany. Among other things, the beer is brewed according to the German purity law of 1516, so that it is produced with only four ingredients (water, malt, hops and yeast) - with the exception of specialities such as hemp beer.
The product range of organic beers in the Wädenswil "Beer Parade" includes the brands Light, Hemp, Dark, Ur-Weizen, Ur-Pils, Pale Ale and Premium Blond. For many years Wädi-Brau-Huus AG purchased the steam from a large capacity water boiler from a neighbouring company, a former silk weaving mill, as a second customer. At this time, it was generously agreed that the number of brews brewed per year would be taken into account. With the liquidation of the silk weaving mill in the neighbourhood and the elimination of the steam supply option, the organic brewery felt obliged and at the same time faced the challenge of taking care of its own steam generation in the future.
Because the brewery is located in the centre of Wädenswil and the space inside and outside the production area is very limited, it was necessary to find a suitable steam generator that would meet all requirements.
