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.
Reasons to trust Mobil COOLANOL
- Superb high- and low-temperature stability
- Versatile and simple to handle
- Manufactured under stringent quality control
- Oxidative stability
- Radiation resistance
- Lubricity
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.
