cpp INSTRUMENTATION, CONTROL, AUTOMATION Pictures: Vega Good lubrication makes everything run better QUICK ACCESS TO ALL LEVEL DATA For more than 100 years now, oils from Oest have ensured that processes and machines of all kinds run smoothly. In the current production facility, Vega sensors monitor the mixing of oils and keep track of stock levels, thus helping the operators maintain a good overview of the many different products and processes. 20 cpp 02-2020
The Georg Oest Mineralölwerk based in Freudenstadt is the heart of the Oest group, which also includes part of the Avia network of petrol stations The origins of Oest go back more than 100 years. It all started in 1915, when a factory for the production of technical oils and lubricants was founded in Dornstetten in the Black Forest. In the following years, the scope of products was continuously increased in order to meet very different customer requirements. By combining various base oils in different ways, the company added many new items to its product range: drive belt wax, drilling oil, leather oil, carriage grease, anti-rust grease, ski wax, sewing machine oil, turbine oils, transformer oils, milling oils, among many others. Not every one of these products is still produced today, though special classic car oils are still in demand, albeit in small quantities. The product portfolio is now broader than ever. Over the years, the company has systematically expanded the development, production and distribution of industrial lubricants. Today, the Georg Oest Mineralölwerk (mineral oil plant) based in Freudenstadt is the heart of the Oest group, which also includes part of the Avia network of petrol stations. Not only was the laboratory expanded and the staff increased at the Freudenstadt location, the storage areas were also gradually enlarged. The requirements on the various production processes are very different. “Some require nitrogen blanketing, others have to be temperature controlled, and yet others require special safety measures for explosion protection. In addition, the requirements of the Water Resources Act (WHG) must be taken into account, as well as the EU chemical classification Reach or the specifications mandated by TÜV,” says Thilo Reich, Head of Engineering at Georg Oest Mineralölwerk, describing the extensive requirements. Fulfilling customer requirements High-quality petroleum raffinates, the base oils, are the basis for the wide range of products. The Black Forest company is constantly working on new developments, for example bio-lubricants, which are quickly biodegradable and based on renewable raw materials. In the company’s own laboratory, the special mixtures are carefully examined and tested so that the resulting lubricants are optimally adapted to each application. Of course, the laboratory is also responsible for quality assurance, so every batch is checked before packaging. The development of lubricants is one thing, but Oest‘s job also includes mixing, filling containers and storing the various components. Therefore, about two years ago, the company built a new warehouse and logistics centre at the Freudenstadt site, enclosing a total area of about 3500 m² with space for more than 4000 pallets. “The requirements in the market have changed, today you have to deliver much faster,” explains Reich. Reliable monitoring of stocks Employees at Oest are supported by the most modern production and mixing technology available on the market. Stainless steel production vessels with various agitators in sizes from 400 to 52,000 l, as well as automatic filling systems, ensure that special requests can be fulfilled even on short notice. Incidentally, such requests do not always concern the composition of the lubricant, but sometimes also the size of the package or container the product is delivered in.
