1. Why Does an Air Curtain Need a PTC Air Heater?
Air curtains are widely used in commercial buildings, supermarkets, factories, cold storage rooms, clean rooms, and other industrial environments.
Their main function is to create a high-speed air barrier at entrances, reducing the exchange of indoor and outdoor air while helping maintain a stable indoor environment.
During winter or in low-temperature conditions, the air from a standard air curtain may feel cold and uncomfortable.
To solve this issue, many air curtain systems are equipped with PTC Air Heaters to warm the airflow before it is discharged, providing a more comfortable and effective air barrier.
PTC air heaters are widely used in air curtain equipment because of their fast heating performance, high safety, and self-regulating temperature characteristics.
2. Working Features of PTC Air Heater in Air Curtain Equipment
PTC Air Heater uses PTC chips as the main heating source. When electricity passes through the PTC element, it quickly generates heat, and aluminum heat sinks transfer the heat to the passing air.
Compared with traditional wire heating elements, PTC air heaters provide several advantages:
- Self-regulating temperature control: PTC materials increase electrical resistance as temperature rises, helping prevent overheating;
- High heating efficiency: Aluminum fins increase heat dissipation area and improve air heat exchange efficiency;
- Safe and reliable operation: No open flame during normal operation, suitable for continuous heating applications;
- Flexible design options: The heater structure can be customized according to airflow, power, voltage, and installation requirements.
In air curtain systems, the PTC Air Heater is usually installed inside the air passage, allowing the airflow from the fan to pass through the heating module and deliver warm air evenly.
3. Customized PTC Air Heater Solutions from JAYE HEATER
Different air curtain manufacturers have different requirements for heating power, dimensions, voltage, installation methods, and insulation levels. Therefore, customized heating solutions are often required.
Most of our PTC Air Heaters can be customized according to customers' parameters and drawings, including:
- Heating power;
- Voltage specifications;
- Dimensions;
- Wire arrangements;
According to different application requirements, Our PTC Air Heaters are mainly divided into two types:
(1) Insulated PTC Air Heater
The insulated type features electrical isolation between the heating element and the external metal structure. It is suitable for applications requiring higher safety standards, such as commercial air curtains, industrial equipment, and special working environments.
(2) Non-insulated PTC Air Heater
The non-insulated type offers a compact structure and efficient heat transfer performance. It is suitable for applications that require fast heating, space-saving designs, and cost-effective solutions.
With flexible customization capabilities, we provides reliable PTC Air Heater solutions for air curtain manufacturers, helping equipment achieve efficient, stable, and safe warm air performance.
