What are the safety features of conductive PTC constant temperature air heaters?
Publish Time: 2024-08-26
1. Stable temperature control
Constant temperature heating characteristics: When the PTC heater is powered on, it can quickly heat up due to its small room temperature resistance and large starting current. As the temperature rises, its resistance value increases rapidly and enters the transition zone. At this time, the current passing through the PTC heater becomes very small, so that the surface temperature of the PTC heater remains at a constant value. This temperature is only related to the Curie temperature and applied voltage of the PTC heater, and has little to do with the ambient temperature. This constant temperature heating characteristic ensures the stability of the heater temperature during operation and avoids safety hazards caused by excessive temperature.
2. Multiple protection mechanisms
Overheat protection: The heater is usually equipped with an overheat protection function. When the temperature exceeds the set value, it can automatically cut off the power supply to prevent the equipment from being damaged by overheating or causing a fire accident.
Anti-electric shock protection: The heater should comply with relevant safety standards and have an anti-electric shock protection function to ensure the electrical safety of users during use.
3. Material and design safety
Material safety: The materials used in PTC heaters, such as PTC ceramics and aluminum alloy corrugated sheets, all meet relevant standards and environmental protection requirements, are non-toxic, odorless, and corrosion-resistant, ensuring the safety and environmental protection of the product.
Sealed moisture-proof design: The surface of the heater adopts a fully sealed moisture-proof design, which improves the safety and durability of the product and reduces the risk of electrical failures caused by humid environments.
4. Stable and reliable performance
Long service life: PTC heaters have a long service life and can withstand long-term use and frequent switching operations, reducing safety hazards caused by equipment aging.
Less affected by power supply voltage fluctuations: The automatic heating adjustment function of the PTC heater makes it less affected by power supply voltage fluctuations, and can maintain a stable heating effect under different voltage environments, improving the reliability and safety of the product.
5. Compliance with standards and specifications
Compliance with safety standards: PTC constant temperature air heaters should strictly comply with relevant safety standards and specifications during the production process, such as international standards such as ISO and IEC and relevant domestic industry standards to ensure product safety and compliance.
Strict quality control: The heater must undergo strict quality control and testing before leaving the factory, including tests on heating efficiency, temperature control, noise, weather resistance, durability, etc., to ensure that the product performance meets the standard requirements.
