コアの利点

Efficient heating and energy saving:

PTC ceramic self-limiting temperature technology: Automatically reduce power when the temperature exceeds the set value to prevent overheating and combustion, and reduce energy consumption by 30% compared with traditional resistance wire.

The thermal conductivity of the nickel-chromium alloy heating element is ≥150W/m·K, and the temperature rises to 100°C within 3 minutes, which is suitable for the rapid heating needs of air conditioners.

Safe and reliable:

IP66 protection level: dustproof and splashproof, suitable for humid or dusty industrial environments.

Automatic power off when tilting: Immediately power off when the tilt angle is greater than 15°, in line with UL/CE safety standards.

Uniform heat dissipation and silent operation:

The aluminum fin design optimizes airflow distribution, and the heat exchange efficiency is ≥95%, avoiding local overheating.

No mechanical vibration noise, suitable for low-noise operation at night.

Corrosion resistance and long life:

316L stainless steel or anodized aluminum is resistant to salt spray corrosion (test ≥500 hours), and the life is 2-3 times longer than ordinary resistance wire.
​​Intelligent compatibility​​:
Supports PWM power regulation and IoT access (APP remote temperature control), and is compatible with smart home systems (such as HomeKit/Alexa).
Can integrate humidity sensors and link air conditioning dehumidification mode to prevent heating from causing excessive dryness in the room.
​​Environmental protection and adaptability​​:
Zero emissions, no odor, in line with the EU ErP energy efficiency directive (A+++ grade).
High humidity resistant design (RH 95%), suitable for air conditioning systems in tropical/coastal areas.
