Soltex Opticool H

Synthetic oil based coolant for marine applications 

OptiCool-H Fluid is a highly efficient dielectric heat transfer fluid used to cool electrical equipment in underwater applications. OptiCool-H has excellent heat transfer characteristics and a very high dielectric strength. 
Containing advanced oxidation inhibitors, it provides longer service life at high temperatures. Compared to standard transformer oil, OptiCool-H biodegrades faster and has better heat transfer characteristics. Gallon for gallon, OptiCool-H Fluid is almost 10% lighter than mineral oil. 
OptiCool-H’s enhanced electronic cooling performance allows equipment to be smaller in size and minimize the operating temperatures in any equipment.
