Properties
Performance Testing and Comparison：
- After a large number of practical applications and long – term tracking tests, YST – 266 has shown good long – term use effects.
- In the process of continuous use for several years, its performance decays slowly and can continuously and stably exert the heat transfer function.
- Compared with other similar products, it has a longer service life, which can effectively reduce the replacement cost of enterprises.
- There will be no obvious viscosity change and acid value increase problems during long – term use, which ensures the long – term and efficient operation of the thermal oil system
Core Features and Advantages
1.Excellent Thermal Stability and Anti-Coking Performance
YST-266 adopts high-quality synthetic base oil and proprietary additive technology, featuring extremely high thermal-oxidative stability.
Even under harsh operating conditions of high temperature and high pressure, it can effectively inhibit thermal cracking and oxidation of the oil, fundamentally avoiding coking and carbon deposition caused by the formation of gums and asphaltenes.
Value to users: Ensures long-term cleanliness of heat transfer systems (especially the precision flow channels of hot plates in continuous presses), maintains stable heat transfer efficiency, and prevents equipment damage, increased energy consumption, and reduced production efficiency caused by coking.
Core Features and Advantages
- Extremely Low Annual Loss Rate (< 2%)
The oil has extremely low vapor pressure and excellent high-temperature volatility. With good system sealing, the normal annual supplementary consumption can be controlled below 2%.
Value to users:
- Economic operation: Significantly reduces the procurement cost of heat transfer oil caused by volatilization and supplementary refueling.
- Environmental protection and safety: Reduces oil vapor volatilization, improves the working environment, and lowers safety risks.
- System stability: Low loss means more stable oil properties, no frequent supplementary refueling for the system, and more reliable operation.
Core Features and Advantages
- Outstanding Safety Factor
——High flash point and auto-ignition point: Provide a wider safe operation range and reduce fire risks.
Excellent heat transfer performance: High heat conduction efficiency, enabling efficient heat transfer with lower system circulation volume and reduce temperature difference, and reducing system load.
System compatibility: Has good compatibility with sealing materials and metal components in the system, protecting equipment and extending its service life. - Wide Application Adaptability
——Specifically designed for industries requiring precise and stable high-temperature heat sources, such as wood-based panel, textile, and chemical industries. It is especially suitable for continuous flat press production lines with extremely high requirements for temperature uniformity. - Operation Status
- Since its commissioning, all indicators of the heat transfer oil system have remained normal. The specific performance is as follows:
- Stable oil performance: After 16 years of long-term high-temperature operation, laboratory analysis of the oil shows that its core indicators (such as acid value, viscosity, carbon residue, etc.) have changed slightly and are still within the safe service range, which proves its ultra-long service life and excellent stability.
- Low equipment maintenance cost: Due to the excellent “anti-coking” performance of YST-266, the internal flow channels of the hot plates in the continuous press of Zhongfu Wood Industry have maintained remarkable cleanliness. There has never been a need for expensive shutdown cleaning or maintenance due to heat transfer oil coking, ensuring the continuous and stable operation of the production line.
- Significant economic benefits: The extremely low annual loss rate (below 2%) has saved Fujian Zhongfu Wood Industry a large amount of supplementary cost for heat transfer oil over 16 years, and the comprehensive energy efficiency has always remained at a high level.
Superior thermal stability
Shanghai Yansen Thermal Oil YST-266 has a high stability under the high temperature environment.
Its molecular structure is engineered to effectively resist thermal decomposition during long-term high-temperature operation. Even at 300°C, it maintains chemical stability without forming carbon deposits or sediments.
This ensures the normal functioning of thermal oil systems, minimizes equipment failures caused by oil degradation, and provides reliable high-temperature heat transfer assurance for industrial production.
