Voith installs intelligent air supply system at König Ludwig Schloßbrauerei Kaltenberg
Heidenheim/Fürstenfeldbruck: In February 2016, the brewery König Ludwig GmbH & Co. KG Schloßbrauerei Kaltenberg in Fürstenfeldbruck started up a completely new returnable glass bottle filling line with a capacity of 45,000 bottles/hour in its existing bottling hall.
The reasons for replacing the system included seeking more energy-saving production higher efficiencies and hygiene requirements, says Technical Director, Helmut Guggeis. The same demands were also made on the hall air system. According to Guggeis, all expectations in respect of planning and execution were exceeded, from the launch of the project in May 2015 until handover of the system in February 2016. The execution, functionality and impact of the new air system have completely fulfilled the company's objective. Voith planned, supplied and installed the air system including a displacement air flow system. This is done by installing air displacement outlets near the floor for supply air intake. Thanks to close cooperation with König Ludwig brewery, the location of the air displacement outlets could be adapted on a system-specific basis. In order to meet the hygiene requirements, the supply air, for instance, is brought into the hall with low turbulence as 100% treated fresh air all year round. Even in winter there is no recirculating air operation. In consideration of the external air volumes to be exhausted at the air cleaning machine, the return air is exhausted system-oriented underneath the hall roof. The ventilation and air exhaust system is designed in accordance with VDI 6022 guidelines. A plate heat exchanger is used for heat recovery. The ventilation unit is equipped with high-quality pocket filter stages - two for the supply air and one for the return air. The filter for the return air is installed on the exhaust air side to protect the heat recovery. As the brewery is located in a residential area, particular emphasis was placed on soundproofing the outside air and outgoing exhaust air openings. The automation technology was planned and installed by Voith in accordance with the brewery's guidelines.
