 Product Characteristics (Core Features)

  • ​Uniform Circular Heating​​: The annular structure ensures 360° even heat distribution, eliminating cold spots—critical for steam irons (consistent steam output), coffee machines (uniform brewing temperature), and humidifiers (stable humidity generation).
  • ​Rapid Heating Efficiency​​: High-conductivity nickel-chromium alloy core heats to 180℃ (optimal steam temp for irons) in ≤3 minutes for 1500W models, reducing wait time across devices. For coffee machines, 2000W models reach 95℃ (ideal extraction temp) in ≤4 minutes.
  • ​Multi-Device Adaptability​​: Customizable outer/inner diameters (100-400mm/40-200mm) and thicknesses (15-50mm) fit mainstream appliances:
    • Steam irons: Annular slots for direct installation to generate high-pressure steam.
    • Coffee machines: Brewing chamber heating plates for consistent water temperature.
    • Humidifiers: Water tank heating elements for efficient mist production.
  • ​Corrosion & Scale Resistance​​: Die-cast aluminum housing resists oxidation and steam corrosion; the smooth anodized surface minimizes limescale adhesion (reduces cleaning frequency by 40% vs. uncoated aluminum). Nickel-chromium alloy core withstands mineral deposits, extending lifespan in high-moisture environments.
  • ​Safe & Reliable Operation​​: Insulated aluminum housing prevents electric leakage; built-in overheat protection (auto-shutoff at >350℃) safeguards against dry burning or overheating. Optional temperature sensor interfaces support ±5℃ precise control (e.g., 40-60℃ for humidifiers, 90-105℃ for coffee machines).
  • ​Lightweight Design​​: Aluminum alloy density (2.7g/cm³) makes the plate 30%-40% lighter than stainless steel alternatives, ideal for weight-sensitive devices like portable steam irons or compact coffee machines.
  • ​Long Lifespan Stability​​: Optimized thermal expansion matching (aluminum and nickel-chromium have similar coefficients) reduces thermal stress fatigue. Maintains stable performance for over 10,000 hours under high-frequency use (e.g., 2 hours daily operation in humidifiers).
