Description
Perfecto™ HT 5: Heat Transfer Oil
Description
Perfecto™ HT 5 is formulated from solvent-refined mineral base oils with a high viscosity index, providing excellent thermal and oxidative stability.
Application
Perfecto HT 5 is primarily used in closed heat transfer systems with bulk oil temperatures up to 300°C (572°F). It can also be used in open systems with lower bulk oil temperatures. Due to its high solubility and thermal stability, Perfecto HT 5 can also be used as an excellent flushing oil for turbine systems.
Advantages
- Controlled Properties: The tightly controlled properties of the oil help to minimize deposits in heat exchangers, maintaining efficient heat transfer.
- High-Temperature Operation: Capable of operating at temperatures up to 300°C in closed heat transfer systems.
