A Thermal Fuse is a component used in compressed air systems and steam systems. These fuses act as the last line of defense and are often used to prevent catastrophic incidents. Thermal fuses protect tanks and machinery from excessive temperature increases.
The thermal fuse consists of a fusible alloy inside a body made of brass, bronze, or steel. The material selected for the fusible alloy has a predefined melting point that is lower than the melting point of the fuse body material.
The operation of the fuse is such that when exposed to temperatures exceeding the specified limit, the alloy inside melts, and the pressure of the tank is released.
Operation with Compressed Air Systems: Thermal fuses act as a safety mechanism by reducing pressure in the compressed air system due to temperature rise, preventing potential explosions or fires.
Operation with Steam Systems: Thermal fuses are installed in boilers to reduce the risk of boiler explosions due to excessive steam pressure buildup.
