Allowing lubricating, hydraulic, or gear oil to overheat can trigger a chain reaction of mechanical issues: Viscosity Breakdown: Overheated oil thins out, losing its ability to provide a protective film between moving metal parts. Oxidation & Sludge: High temperatures accelerate chemical breakdown, forming harmful varnish and sludge that clog filters and valves. Seal Degradation: Excessive heat hardens and cracks internal seals, leading to hazardous fluid leaks. By integrating a premium oil cooler, you stabilize fluid properties, drastically lowering your total cost of ownership and preventing catastrophic equipment failure.
