Maxothermie^®650

Maxothermie®-650 is a high-performance synthetic heat transfer fluid engineered for non-pressurized and low-pressure indirect heating systems operating at high temperatures. It is designed for reliable operation in closed-loop heating systems across a wide liquid-phase temperature range of 0°C to 350°C, offering excellent thermal stability, high purity, and superior heat transfer performance.

Operating Temperature

Key Features & Benefits

• Wide operating temperature range: 0°C to 350°C (bulk) with film temperatures up to 370°C
• Excellent thermal stability ensures reliable performance at elevated temperatures
• Suitable for non-pressurized and low-pressure heating systems
• High purity (≥98% Polyarylalkane / Dibenzyltoluene isomers) enables consistent fluid performance
• Low cold viscosity facilitates easier start-up while reducing pumping energy requirements
• High boiling point (390°C) minimizes evaporation losses and improves operational stability
• High auto-ignition temperature (470°C) enhances safety in high-temperature applications
• Low pour point (–34°C) supports storage and handling in colder environments
• Low acidity (<0.02 mg KOH/g) helps maintain system cleanliness and fluid integrity
• Excellent heat transfer properties improve temperature uniformity and process efficiency
• Simplified monitoring of fluid ageing and top-up management due to its well-defined chemical composition
• Ideal for applications in oil & gas processing, refining, plastics & polymer manufacturing, synthetic fibre production, specialty chemicals, biofuels, desalination, food processing, paper, and beverage industries.
