Medium Circulating System Oil
Overview
Medium Circulating System Oil is a high-performance lubricant formulated for industrial systems requiring consistent oil circulation. It ensures smooth operation of machinery by reducing friction, dissipating heat, and protecting components from wear. Its balanced viscosity and additives make it suitable for moderate-temperature applications. Unlike general-purpose oils, this product is optimized for closed-loop systems where oil longevity and thermal stability are critical. It is commonly used in manufacturing plants, power generation, and heavy machinery where equipment reliability is paramount.
Physical and Chemical Properties
The oil typically exhibits a clear to pale yellow appearance with a density range of 0.85-0.90 g/cm³. Its high boiling point (>200°C) and low volatility ensure minimal evaporation losses during operation. The formulation often includes anti-wear additives like zinc dialkyldithiophosphate (ZDDP) and oxidation inhibitors. Key properties include a viscosity index (VI) of 90-110, ensuring stable performance across temperature variations. It is insoluble in water but compatible with most mineral-based and synthetic lubricants. Flash points typically exceed 180°C, enhancing safety in industrial settings.
Main Applications
This oil is primarily used in hydraulic systems and gearboxes where continuous circulation is required. It serves as a heat transfer medium in industrial chillers and compressors, ensuring efficient thermal management. In paper mills and steel plants, it lubricates heavy-duty rollers and bearings. Other applications include centralized lubrication systems in automotive manufacturing and CNC machinery. Its oxidation resistance makes it suitable for extended service intervals, reducing downtime and maintenance costs. Always consult equipment manuals for OEM specifications.
Safety and Storage
Store in sealed containers away from moisture and contaminants. Use grounded metal drums to prevent static discharge. In case of spills, absorb with inert materials like sand and dispose of according to local regulations. Personal protective equipment (PPE) such as nitrile gloves and safety goggles should be worn during handling. Avoid inhalation of vapors during high-temperature operations. The oil is not biodegradable; follow EPA or REACH guidelines for disposal. MSDS sheets must be reviewed prior to use.
B2B Procurement Guide
When sourcing, prioritize suppliers with ISO 9001 or ISO 14001 certifications. Request technical datasheets to verify viscosity grades (e.g., ISO VG 46) and additive packages. Bulk purchasing (200L drums or IBC totes) often reduces costs by 10-15%. Evaluate total cost of ownership (TCO), including oil life and filter compatibility. For critical systems, consider oil analysis services to monitor degradation. Leading manufacturers include Shell, ExxonMobil, and TotalEnergies. Sample testing is recommended before large-scale procurement.
