- Features
Dynalene’s molten salt fluids have excellent thermophysical properties in the liquid state, such as low viscosity, high heat capacity, and high thermal conductivity. The high energy density of Dynalene’s molten salts provides long-term heat storage for any high-temperature application. Our heat transfer salts provide excellent corrosion resistance with stainless and alloy steels and exhibit minimal vapor pressures even near peak operating temperatures. This eliminates the need for expensive materials and high-pressure components, in addition to increasing the safety of your system.
Thermal Stability
The maximum operating temperature of MS-1 is 565°C . Above this temperature the fluid will slowly evolve into non-toxic, inert gasses with very low vapor pressures. Prolonged exposure to temperatures higher than the recommended maximum operating temperature may lead to precipitate formation.
Corrosion Performance
Dynalene MS-1 has undergone repeated corrosion testing. Stainless steel samples were immersed in the salt for 36 days at 550°C (1022°F) and then evaluated for mass loss. The recorded corrosion rates for SS-304 and SS-316 are 21 µm/year and 16 µm/year, respectively.
Material Compatibility
Dynalene MS-1 can be used safely with carbon steel up to 400°C (752°F). Above this operating temperature, stainless steel, Inconel, or other corrosion-resistant alloys are recommended. Copper and bronze can be used up to 300°C (572°F).
