Mobil™ COOLANOL™ 25R MIL-C-47220B Type IV Spec Silicate Ester Dielectric Heat Transfer Fluid - 5 Gallon Pail

Exxon Mobil's Coolanol 25R is part of a series of silicate ester dielectric heat transfer fluids. These fluids are specially formulated to address the needs of sensitive electronic components and environmental control systems in aircraft, missiles and spacecraft. Coolanol fluids' superior quality makes them reliable safeguards against costly and potentially catastrophic failure of critical airborne electrical equipment.

In particular, Coolanol fluids are intended for liquid circulating systems (dynamic liquid phase) found in high-density electronic packages in aerospace and military applications. Because of their excellent heat transfer efficiency, the aforesaid systems are in wide use. However it's important to note that Coolanol should not be used in vaporizing (boiling liquid) systems.

Moreover, Coolanol fluids provide excellent thermal stability, evident by their ability to endure both high and low temperature extremes that airborne electronic equipment usually encounter. Thus, because of their dielectric, heat transfer, hydraulic and lubricating properties, these fluids function well in dynamic systems over an exceptionally wide temperature range.

For quality assurance Exxon performs required OEM tests, as well as their own tests, to ensure that every batch of product conforms to the highest standards.
