Description

Exxon Mobile Coolanol OS-59 Ester Dielectric Heat Transfer Fluid MIL-C-47220B TYPE III – 5 GL Pail

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 COOLANOL is an important additional safeguard against costly and potentially catastrophic failure of critical airborne electrical equipment.

Features & Benefits of Exxon Mobil COOLANOL OS-59 Ester Dielectric Heat Transfer Fluid

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 of Exxon Mobil COOLANOL OS-59 Ester Dielectric Heat Transfer Fluid

To select the proper COOLANOL fluid for a given application, first determine the upper and lower temperature parameters of the application.

  1. Coolanol 20:  (-101 – 149 °C / -150 – 300 °F)
  2. Coolanol  25R:  (-54 – 149 °C / -65 – 300 °F)
  3. Coolanol OS-59: (-54 – 288 °C / -65 – 550 °F)
