The long-life Sialon aluminium immersion heater is the ideal solution for molten non-ferrous heating and handling now up to 1100° Celsius or 2012° Fahrenheit! With a limited 12 months warranty period against electrical defects, you can be confident in its performance.
Direct heating with an aluminum heater, particularly using Sialon ceramics, offers significant advantages for molten non-ferrous metal processing, These heaters, designed for applications like die casting and degassing, provide unmatched efficiency and precision.
Energy efficiency is a standout feature. Sialon aluminum immersion heaters achieve over 99% energy efficiency, saving 30-50% compared to traditional methods. By directly heating molten metals like aluminum, magnesium, or zinc, they minimize heat loss, reducing energy costs by up to 40%. This efficiency lowers operating expenses and supports decarbonization by cutting CO2 emissions.
Precise temperature control ensures high-quality results. These heaters maintain flow temperature accuracy within ±2°C, preventing overheating that could damage metal purity. This reduces oxides, corundum, and dross, enhancing cast part quality and minimizing metal losses during production. The result is stronger, more reliable products with fewer defects.
Durability and corrosion resistance are critical. Sialon’s silicon nitride-based composition offers superior resistance to chemical corrosion in harsh molten metal environments. With a high melting point and low thermal expansion, these heaters withstand temperatures up to 1100°C, ensuring long-term reliability and reduced maintenance costs. A 12-month warranty against chemical attack and electrical defects underscores their robustness.
Versatility and customization make these heaters ideal for high-pressure die casting, filtration, and ladle reheating. With customizable power, voltage, and sheath sizes, they meet diverse industrial needs. The use of advanced materials like silicon nitride enhances thermal conductivity and shock resistance, optimizing performance in demanding settings. Sialon aluminum heaters deliver cost-effective, eco-friendly, and high-performance solutions for modern metallurgy.
Sialon ULTRA™ Aluminium Immersion Heaters are the superior direct-heating solution for molten non-ferrous metals (aluminium, magnesium, zinc) up to 1100 °C (2012 °F). Manufactured from advanced silicon nitride-based Sialon ceramics (Si₃Al₃O₃N₅), they achieve over 99 % energy efficiency, deliver 30–50 % energy savings compared to traditional methods, and provide precise temperature control of ±2 °C – preventing overheating, oxide formation and dross while maintaining highest metal quality.
The non-wetting surface eliminates metal adhesion, while exceptional thermal shock resistance (550–900 °C), zero water absorption and outstanding corrosion resistance ensure years of trouble-free operation in aggressive molten-metal environments. Ideal for high-pressure die casting, filtration, ladle reheating, gravity casting and integration into Striko Westomat dosing furnaces (450–3,100 kg capacities).
