Industrial systems suffer when fluids such as hydraulic fluids, compressor oils, or machining fluids lack the proper performance characteristics. Insufficient lubrication and wear protection can cause accelerated component wear and operational inefficiency, while thermal and oxidative challenges cause premature degradation and sludge.
