Sinopec L-QC 320 Heat Transfer Oil is formulated from high-quality, narrow-cut mineral base oils, combined with advanced detergent, dispersant, and anti-oxidation additives. It is recommended for use in closed heat transfer systems where the maximum bulk oil temperature does not exceed 310°C and the film temperature does not exceed 320°C.
Key Features
1.Excellent Thermal Stability: The oil resists cracking and degradation at high temperatures, extending oil life and reducing system maintenance costs.
2. Low Flash Point and Low Volatility: Enables safe operation in closed systems up to 310°C.
3. High Specific Heat and Thermal Conductivity: High thermal efficiency, improving operational performance and reducing energy costs.
4. Good Low-Temperature Fluidity: Ensures easy circulation even during cold start-ups.
5. Anti-rust and Anti-corrosion: Protects the system and reduces maintenance costs.
6. High Detergency: Keeps the system clean and minimizes deposits, extending operation cycles.
Main Applications
– Closed heat transfer systems (with forced or natural circulation) operating at bulk temperatures up to 310°C.
– Drying and heating processes: wood processing, textile finishing, food processing.
– Chemical, synthetic fiber, plastic, medical, printing, and dyeing industries.
– Plastics industry: injection molding machines, pelletizers, shrink films.
– Food industry: drying, cooking equipment.
– Rubber, paint, and paper industries.
