MINERAL
SUPRACAL
Application
Highly refined mineral oil with paraffinic tendencies for heat transfer and thermal controls operating at temperatures up to 280°C. Can be used for dynamic circulation as well as static applications.
Advantages
- Perfect stability at high temperatures.
- High resistance to oxidation.
- Excellent anti-rust, anti-corrosion and anti-foam properties.
- Low viscosity for excellent thermodynamic characteristics.
- Very low vapour pressure.
- Non-toxic, zinc-free.
