High-Temperature, High-Reliability Heating for Advanced Thermal Processes
Molten salts have become one of the most reliable heat-transfer media for processes that require extremely high operating temperatures, excellent thermal stability, and long service life.
At Sinton, we engineer electric heating systems specifically designed to heat, melt, circulate, and maintain molten salt in industrial environments — ensuring stable, safe, and efficient operation across a wide range of applications.
What Are Molten Salts?
Molten salts are inorganic compounds—typically fluorides, chlorides, or nitrates—that become liquid at elevated temperatures. Once melted, they offer:
Outstanding thermal stability at temperatures up to 600–900°C
High specific heat capacity for uniform heat transfer
Very low vapor pressure, even at extreme temperatures
Long service life compared with organic thermal oils
These characteristics make molten salts ideal for high-temperature industrial heating, thermal energy storage, and specialized heat-treatment processes.
Why Molten Salt Heating? Key Advantages
Operates at Ultra-High Temperatures
Molten salts can safely operate above 1,000°F (540°C) without the degradation issues seen in mineral oils.
Excellent Heat Transfer
High thermal conductivity ensures fast temperature response and stable heating performance.
Safe & Environment-Friendly
Non-flammable, non-toxic, and extremely low vapor pressure reduce safety risks.
Long-Term Cost Efficiency
Minimal fluid replacement, low emissions, and reduced maintenance requirements.
Sinton Molten Salt Heating Systems
Our industrial electric heaters are engineered to support all categories of molten-salt systems, including:
1. Salt-Melting Heaters
Used during startup when solid salts must be brought above their melting point.
Features: uniform heat input, precise temperature control, and anti-corrosion design.
2. Circulating Molten Salt Systems
Designed to maintain molten salt above its freezing point while providing stable circulation to the process.
Includes:
Flange heaters or immersion heaters
Circulation pumps
Hot salt tank
Temperature, level, and flow monitoring
3. Direct Molten Salt Process Heating
High-power heaters directly immersed into molten salt tanks for industrial, thermal storage, or heat-treating applications.

Engineering Challenges & How Sinton Solves Them
Freezing Point Management
Many molten salts have high freezing points (120–220°C).
Sinton Solution: independent heating zones + heat tracing + smart startup program.
Corrosion & Material Compatibility
Improper metallurgy leads to heater element failure.
Sinton Solution: alloy selection based on salt composition (nitrates, chlorides, fluorides).
Temperature Uniformity
Uneven heating may cause salt stratification.
Sinton Solution: optimized watt density and heater placement.
Startup From Solid Salt
Salt must be melted safely and evenly.
Sinton Solution: staged power control + low-watt-density melting heaters.
