Naftas ® Lubricants
Heat Transfer Oil
Naftas® Heat Transfer oils are designed to satisfy the unique needs of high-performance heat transfer systems. They have exceptional heat, rust, and corrosion resistance, as well as superior oxidation and thermal stability. These characteristics serve to maintain the components safe and operational at all times.
Naftas® heat transfer oils are made with high-quality components and additives with antioxidant qualities that prevent deposits and thermal degradation, resulting in long service life.
Products are packed in barrels with a capacity of 205 L






HEAT TRANSFER oil
Ideal oil for various manufacturing operations
The following are a few of their primary advantages:
- They are designed to provide outstanding protection against rust and corrosion, resulting in significantly reduced heat transfer system wear and tear.
- Naftas® heat transfer oils offer unrivaled oxidation and thermal stability thanks to anti-oxidant compounds and low residue base oils.
- They’re designed to provide superior wear and tear protection, extending the equipment’s operational life and preserving its value.
- Low coking and residue-forming base oils have been carefully selected.
- Naftas® heat transfer oils have a high viscosity, which allows for excellent fluidity and a wide operating range.

Applications:
- Heat Transfer Oils 22 and 46 are recommended for use in closed, liquid-phase, forced circulation heat transfer systems equipped with expansion tanks and pressure relief valves, where the maximum bulk oil temperature does not exceed 550°F (288°C). Preventive measures should be taken to minimize oil oxidation by eliminating air from the system prior to bringing the oil up to operating temperature. The use of inert gas, such as nitrogen, under positive pressure in the expansion tank, is recommended at all times during operation. Under no circumstances should the hot oil come into contact with air.
- Heat Transfer Oils 22 and 46 also are recommended for use in open, liquid phase, forced circulation heat transfer systems where the maximum bulk oil temperature does not exceed 374°F (190°C).
- Skin film temperature can be estimated at 50°F to 75°F above bulk oil temperature in properly designed and operating systems. If skin film temperatures rise higher than this, the service life of the oil may be shortened. Additionally, sludge and coke may be deposited resulting in reduced efficiency of the system.
- Some common heat transfer applications include:
– Direct and indirect-fired hot oil heaters in asphalt plants
– Hot corrugation and gluing
– Dehydration
– Molding and extrusion equipment
– Plastic and wax coating equipment
– Organic synthesis hot oil systems
