ExxonMobil aviation , United States
Product Description
Mobil COOLANOL™ silicate ester synthetic dielectric heat transfer fluids are designed to meet the special needs of sensitive electronic components and environmental control systems in aircraft, missiles and spacecraft.
The proven quality and reliability of Mobil COOLANOL is an important additional safeguard against costly and potentially catastrophic failure of critical airborne electrical equipment.
Features and Benefits
COOLANOL is specifically intended for liquid circulating systems (dynamic liquid phase) found in high-density electronic packages in aerospace and military applications. Such systems are in wide use because of their excellent heat transfer efficiency. COOLANOL should not be used in vaporizing (boiling liquid) systems.
Superb High and Low Temperature Stability
Versatile and Simple to Handle
Manufactured under Stringent Quality Control
Oxidative Stability
Radiation Resistance
Lubricity
Applications
To select the proper COOLANOL fluid for a given application, first determine the upper and lower temperature parameters of the application.
• Coolanol 20: (-101 - 149 °C / -150 – 300 °F)
• Coolanol 25R: (-54 - 149 °C / -65 – 300 °F)
