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)
