Product Description
Thermaflo® RP is a recycled synthetic heat transfer fluid based on diaryl alkyl chemistry, engineered for demanding liquid-phase thermal management in closed-loop, non-pressurized systems. This fluid stands out for its unique degradation characteristics—when thermal breakdown occurs, it produces lighter molecular compounds rather than heavy residues, virtually eliminating the sludge accumulation that plagues many conventional thermal fluids. Combined with an exceptionally high flash point of 188°C (370°F), Thermaflo® RP offers both operational reliability and enhanced safety margins for high-temperature industrial processes.
- Clean Degradation Profile: Breaks down into lighter compounds during thermal stress, minimizing system fouling and reducing maintenance interventions.
- Elevated Flash Point: At 188°C (370°F), provides substantial safety margins for operations near maximum temperature limits.
- Favorable Cold-Weather Characteristics: Remains pumpable down to -10°C (14°F), simplifying system start-up and reducing heat tracing requirements.
- Minimal Vapor Pressure: At only 8 psi at 316°C (600°F), enables reliable non-pressurized system operation at elevated temperatures.
