• Specification

• Function and Application

1. Regulate Oil Temperature
Cool lubricating oil or hydraulic fluid, preventing overheating during heavy operation. High temperatures can cause oil to thin, reducing lubrication effectiveness and increasing wear on components such as bearings, seals, and pumps.

2. Maintain Viscosity and Performance
Ensure the oil remains within its ideal viscosity range, which is essential for efficient power transfer and consistent system performance. Proper viscosity reduces energy losses and improves overall efficiency.

3. Extend Oil and Component Life
By keeping oil cool, it slows down oxidation and degradation, extending the lifespan of both the oil and the machinery. This reduces the frequency of oil changes and component replacements, saving maintenance costs.
