When heat is introduced to a thermal fluid the molecules that make up the fluid exhibit an increase in their kinetic energy, the spaces between the molecules increase and the overall volume of the fluid increases.
It is critical when designing any system using heat transfer fluids to account for this increase through proper sizing of expansion tanks and reservoirs. Our thermal expansion calculator requires only density data and temperature differentials (expressed in either degrees Celsius or Kelvin) to calculate coefficient of thermal expansion.
