SG-25 HEAT TRANSFER “THERMIC”OIL
SG-25 Heat Transfer Oil is blended from the finest select high viscosity index severely solvent refined, severely hydrotreated 100% pure paraffin base oils available. It is a Non-Corrosive, Non-Fouling, Paraffinic Heat Transfer Fluid that is formulated to provide fast and efficient heat transfer when used in open loop or closed system applications with expansion tank temperatures up to 600°F (315°C). Heat Transfer Oil’s operability temperature is from 20°F (-7°C) to a maximum film temperature of 600°F (315°C).
It has good heat transfer efficiency with better resistance to thermal cracking and chemical oxidation. They have high specific heat and good thermal conductivity providing more rapid heating & greatersystem flexibility.
APPLICATION:
It is highly recommended for non-pressurized, closed system application with expansion tank temperatures up to 315°C where Flash and Fire Points significantly above 190.89°C. Such systems are mainly used in Food Processing, Plastics & Metal Industries, Pharmaceuticals, Construction, Laundries, Asphalt Plants, Chemical Plants, Waxes, Resin, Fiberboard, Grease, Rubber, Soap and other industries etc.
FEATURES:
- 1. High Viscosity Index results in a minimum change in viscosity over a broad temperature.
- 2. Excellent Heat TransferProperties, Maximize cooling.
- 3. Excellent hydrolytic stability and resistance to emulsification with water.
- 4. Virtually odorless and essentially non-toxic and Non- fouling on degradation.
- 5. Long service life for proven trouble-free operation.
- 6. Excellent hydrolytic stability and resistance to emulsification with water.
- 7. Excellent compatibility with other petroleum base heat transfer oils.
- 8. Excellent compatibility with all types of seals, materials of construction and finishes commonly used in heat transfer systems.
