About ITRES
ITRES is the brand of Ekleft International GmbH, headquartered in Berlin, and operates an engineering intelligence platform for friction units such as plain bearings and seals in turbomachinery. The company supports R&D departments in the transition from classic Babbitt bearing alloys (ASTM B23 and equivalents) to carbon fiber-reinforced polymer composite materials (PCM) based on PEEK. The service portfolio includes technical consulting, training, bespoke research and development, and integration into production. In-house testing and analysis methods include thermomechanical profiling, hardness correlations (Brinell/Shore), structural integrity investigations, tribological thermal profiling with in-situ temperature measurement at the friction point, COF analyses, wear assessment and dynamic wear models. The target audience is manufacturers and operators of critical rotating equipment components in the context of Industry 4.0 and predictive maintenance. The communication and working languages are English and German.
