Product Description

320w Silver Gray Constant PTC Ceramic Air Heater / Heating Element For Air Conditioner

Detailed parameters

Length(mm)	Width(mm)	Thickness(mm)	Insulation voltage(V)	Switch temperature(°C)	Fan speed(m/s)	Power(w)
48	46	15	3750	250	5	320

Features

1.	Restore automatically after invalidation
2.	PTC heater safety, environmental protection
3.	The higher the temperature, the more power efficient
4.	It is safe when liquid is burnt out in liquid heating device
5.	PTC hearter does not require temperature controlling system
6.	Heating power(W) and self-regulating function is in correlation to the heat dissipation rate.

Notice

1. This type of PTC air heater need a fan to blow, usually the faster is the air blowing speed, the larger is the power.

2. When PTC is used in very low ambient temperature, it have to be special designed.

3. PTC heater do not be damaged without air blowing, but the power is very low.

4. Low air resistance air heater, heat sink density is low, less wind resistance, noise is also smaller, but the power density is smaller than the general ripple.

Applications

applications

First bought samples for lab validation, then placed 800pcs order for resale to local industrial customers. This corrugated aluminum PTC heating element has excellent self‑limiting temperature feature, overheat protection works well under continuous running. Heat dissipation performance is better than other suppliers we tried. Customer feedback is positive, already arranging repeat purchase.

We ordered 1200 pcs corrugated aluminum PTC heating elements for our industrial heating equipment. Self‑limiting temperature function works reliably, built‑in overheat protection gives us extra safety guarantee. The corrugated aluminum structure brings good heat dissipation. Batch consistency is good, mass production delivery was on time. We will re‑order for our new project.

Received 600pcs PTC heating elements after sample testing. Self‑temperature‑limiting performance meets our industrial application requirements. Overheat protection triggers as expected. The only suggestion is that the wire terminals could be more diversified for different assembly ways. Overall satisfied with this supplier. 评论人： Luis Herrera
