Description
Sinopec L-QD 400 Synthetic Heat Transfer Oil has excellent high-temperature thermal stability and is a kind of bicomponent synthetic aromatic substance with a conjugated structure. It is recommended for use as a heat transfer fluid in closed, forced, or unforced circulation systems where the bulk oil temperature does not exceed 390℃. It is widely used in petroleum chemicals, synthetic fiber, synthetic resin, medicine, printing and dyeing, power generation, and other industries.
Applications:
Sinopec L-QD 400 Synthetic Heat Transfer Oil is suitable for use in:
- Closed heat transmission systems with forced or unforced circulation operating at a maximum bulk temperature of 390℃.
- Drying and heating processes, such as those used in timber processing, textile finishing, food processing, and the chemical industry.
Features and Benefits:
- The aromatic oil has a high distillation point: Avoids pressure build-up in the closed circulation system.
- 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 390℃.
- High specific heat and thermal conductivity: Ensure 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.
- Used aromatic oil: Can be recycled or retreated to protect the environment.
