NF 750W 24V Low Voltage PTC Air Heater

Short Description:

The working principle of PTC air heater is based on the characteristic that the resistance of PTC material increases as the temperature rises. When the PTC heater is turned on, the ceramic heating element inside it begins to heat up and transfers heat to the air flowing through it via the heat dissipation structure such as aluminum tubes, thus achieving air heating. As the temperature rises, the resistance of the PTC material gradually increases, thus limiting the further increase of current and avoiding overheating, achieving the function of self-regulated temperature.

Description

When it comes to heating solutions, PTC (Positive Temperature Coefficient) air heaters are becoming increasingly popular due to the numerous advantages they offer over traditional electric air heaters. PTC air heaters are designed to provide efficient, reliable heating for a variety of applications, making them the first choice in many industries.

1. High efficiency and energy saving: PTC heaters have lower energy consumption and higher thermal efficiency, which can heat the air to the desired temperature in a short time while avoiding unnecessary energy waste.
2. Safe and stable: PTC heaters have overheat protection and automatic shut-off functions, which can cut off the power in time when the temperature rises abnormally to prevent fire and other safety accidents. In addition, PTC materials do not burn or produce harmful gases, which have high safety performance.
3. Long service life: PTC heaters are made of high-quality materials and advanced manufacturing techniques, which have high durability and reliability, and can operate stably for a long time without malfunctions.
4. Easy to control: PTC heater temperature control is simple and convenient, which can be achieved by adjusting the power supply voltage or current.

In summary, the advantages of PTC air heaters over electric air heaters make them an excellent heating solution for many industries. Their self-regulating properties, energy efficiency, fast and even heating, durability and versatility make them an excellent choice for businesses looking for a reliable and cost-effective heating solution. As technology continues to advance, PTC air heaters are likely to become more common in the heating industry.
