ULTRAMAX SC400, una cartuccia con sigilatura assolutamente stagna, compatibile con le temperature.

L'ossido di magnesio con cui sono costruiti i riscaldatori a cartuccia ad alta densità di potenza è un eccellente isolante. If the temperature of the heater’s head does not exceed 260°C, the head sealing can be made in resins or silicone, but for higher temperatures or higher safety ratios, other solutions are required. Rotfil found and patented the solution to this problem: SC 400 is a sealant perfectly tight to humidity, irreversible, resistant to high pressures and continuous high temperatures of up to 400 °C. It does not change its structure or characteristics in the years, it is resistant to humidity, acids, air pollution, and does not char. SC 400 is an inorganic compound that is fused into the heater’s head in a controlled-cycle process, thus forming a cohesive seal adherent to the metal surfaces at molecular level. It totally protects all internal components from pollution and oxidation, increasing the life of the heater. Its standard construction is not immersion-proof. The use of SC 400 is indispensable every time you need a high safety level and high reliability. Typical application fields include medical and surgical equipment, aerospace, nuclear-energy, military.
