Description
Sinopec L-QC 320 Heat Transfer Oil is formulated using refined special narrow fraction mineral base oil and special additives with excellent detergency-dispersibility and high-temperature oxidation resistance. It is recommended for use as a heat transfer fluid in closed heat-transfer systems where the bulk oil temperature does not exceed 310℃. It is widely used in the petroleum chemical industry, synthetic fiber, synthetic resin, medicine, printing and dyeing, and other industries.
Applications:
Sinopec L-QC 320 Heat Transfer Oil is suitable for use in:
- Closed heat transmission systems with forced or unforced circulation operating at a maximum bulk temperature of 310℃.
- Drying and heating processes, such as those used in timber processing, textile finishing, food processing, and the chemical industry.
Features and Benefits:
- Excellent thermal stability: Ensures the oil does not crack, break down, or produce deposits at high temperatures, extending the life of the oil, protecting the system, and reducing maintenance costs.
- High flash point and low evaporation rate: Enable the oil to be used in closed systems up to 310℃.
- High specific heat and thermal conductivity: Enable rapid heat transfer, improved operating efficiency, and lower operating costs.
- Good fluidity at low temperatures: Ensures good oil circulation, even at low-temperature start-up.
Good rust and corrosion resistance: Protect the system and reduce maintenance costs.
