High temperature thermal oil heater

How to Prevent Thermal Oil Degradation in High-Temperature Oil Chillers (up to 400°C) Direct Answer: Thermal oil degradation in high-temperature systems (up to 400°C) is primarily caused by thermal cracking (overheating) and oxidation (exposure to oxygen). To prevent premature fluid failure and system coking, facilities must utilize fully closed-loop expansion systems with nitrogen blanketing, maintain high turbulent flow velocities to avoid localized hot spots, and strictly enforce proper heat-up and cool-down protocols. Understanding the Enemies: Oxidation and Thermal Cracking Operating an oil temperature controller at extreme temperatures ranging from 300°C to 400°C is fundamentally different from standard 200°C operations. At these ultra-high temperatures, the...
