What makes a heat transfer fluid better?
Some heat transfer fluids function better in closed systems while others offer superior performance in more open systems such as plastic processing. While fluids are made of a variety of basestocks, the use of additive packages such as oxidation, rust and corrosion inhibitors is what makes the difference between a short life and long life fluid. If your system is open to the atmosphere, using a proper fluid such as Duratherm 600 will keep the system running longer and cleaner between oil changes.
