Messer supplies nitrogen in Hungary for quality assurance of non-alcoholic beverages and fruit juices. At its new site near Budapest, the Hungarian company Gramex possesses a modern PET-bottle filling system with a nitrogen purging station for which Messer annually supplies over 700,000 cubic metres of nitrogen. The bottles are purged with gaseous nitrogen prior to being filled. This process protects preservative free beverages from spoiling by oxidation.
