Mobiltherm 605
Mobiltherm 605 is part of the Mobiltherm 600 Series, a range of high-performance heat transfer oils formulated for use in closed and open indirect heating systems. These oils are produced from highly refined base stocks that offer excellent resistance to thermal cracking and chemical oxidation, ensuring reliable performance in demanding industrial applications.
One of the key advantages of Mobiltherm 605 is its outstanding thermal stability. The formulation resists degradation at elevated temperatures, helping to prevent sludge and coke formation. This ensures clean system operation, maintains heat transfer efficiency and reduces maintenance requirements over extended service intervals.
Mobiltherm 605 also delivers excellent heat transfer efficiency. Its optimised viscosity and thermal properties allow for effective heat circulation and rapid heat dissipation, ensuring consistent temperature control across the system. This contributes to improved process performance and lower operating costs.
Another important benefit is its long operational life. The oil’s resistance to oxidation and thermal degradation helps maintain stable viscosity and performance over time, reducing the need for frequent oil changes and minimising system downtime. It also offers good low-temperature fluidity, supporting easier start-up and reliable circulation in colder conditions.
Mobiltherm 605 is recommended for use in closed indirect heating systems operating at bulk oil temperatures up to approximately 315°C and in open systems up to approximately 180°C. It is suitable for a wide range of industrial applications requiring consistent and efficient heat transfer, including chemical processing, manufacturing and process heating systems.
Physical characteristics include kinematic viscosity of approximately 30.4 mm²/s at 40°C and 5.4 mm²/s at 100°C. Mobiltherm 605 has density of approximately 0.857 kg/L at 15°C, flash point of approximately 230°C and pour point of approximately −12°C. The oil delivers reliable heat transfer performance, excellent thermal stability and extended service life in demanding industrial environments.
