Rodutherm® 66
Rodutherm® 66 is a synthetic heat transfer fluid for closed-circulation industrial heating systems. The product is used in installations where stable and uniform heat transfer is required, such as in the chemical industry, process industry, and other thermal process plants.
This heat transfer oil has been developed for reliable operation at elevated temperatures and supports efficient heat transfer across the entire system. Rodutherm 66 is characterized by good thermal stability, controlled viscosity, and a low tendency to deposit when used correctly and with appropriate system design.
For B2B users, Rodutherm 66 offers benefits in process control, operational reliability, and maintenance planning. A stable thermal medium helps limit temperature fluctuations, supports consistent product quality, and can contribute to a longer service life of components in the heat transfer circuit.
