Fluid Technology

Oils, fats, fuels – flowing smoothly

Corrosion and wear cause an estimated 35 million euros in unnecessary losses each year in Germany alone. Our expertise with fluids helps cut costs and save materials. Our consultation in this area goes far beyond the usual range of tests. Whether in engineering, power plants, the steel industry, mining, or the food industry – tribology becoming increasingly important in many industries.

Avoid corrosion and wear

Using optimised lubricant can reduce or avoid the huge losses. At the same time the operational reliability of machinery and equipment increases, which in turn lowers the cost of production. Our experts will help you through chemical, physical and technological studies and assessments of lubricants, hydraulic fluids, and fuels. Compatibility testing of liquids with standard elastomer or customer gaskets and corrosion tests with different metallic materials. If we check your products from us on a regular basis for consistent product quality, we award the TÜV NORD seal of approval, which then may be placed on these products.
