Principales ventajas

​​Self-limiting temperature safety feature:

No external thermostat is required. When the temperature exceeds the Curie point, the resistance rises sharply, and the power is automatically reduced to a safe range to prevent overheating and burning.
​​High efficiency and energy saving:
Thermal efficiency is ≥95%, electrical energy is directly converted into thermal energy, and energy consumption is reduced by 30% compared with traditional resistance wire heaters.
​​Fast response and silent operation:
The heating speed is ≤30 seconds (to 200°C), no mechanical vibration noise, suitable for silent home appliances (such as air purifiers, medical equipment).
​​Long life and high reliability:
No risk of oxide wire burning, life is 2-3 times longer than that of resistance wire heaters, and it is resistant to frequent start and stop (>10,000 cycle tests).
​​Environmental adaptability:
Moisture-proof, dust-proof, and corrosion-resistant design (optional IP68/IP69K protection level), suitable for humid or harsh industrial environments.
​​Lightweight and compactness:
The aluminum heat sink has a low density (2.7g/cm³), and the volume is 50% smaller than that of traditional heaters, suitable for space-constrained scenarios.
​​Intelligent compatibility:
Supports PWM power regulation and IoT access (APP remote temperature control), suitable for smart home/Industry 4.0 systems.
​​Global Compliance​​:
CE, UL, CCC, RoHS certified
