Today's heat transfer fluids are designed to operate over a long period of time with high production efficiency - if the fluid and system are maintained properly. However, factors such as contamination, oxidative or thermal degradation decrease a fluid's heat transfer capability, shorten its life and possibly cause damage to the system itself. Along with initiating a regular schedule of fluid testing, there are a number of functions that the operator can perform on a regular basis and some important information to keep in mind to ensure peak system performance and maximum fluid life.
