Why choose PTC electric heater

In ventilation and air conditioning, fresh air systems and air treatment equipment, some scenarios require rapid heating or auxiliary heating of the air. For example, winter fresh air preheating, clean room temperature control, equipment anti-freeze protection, industrial air heating, etc. If the heating equipment is not selected appropriately, problems such as slow heating, high energy consumption, unstable temperature, or increased safety risks may occur.

PTC electric heater uses PTC heating element, which can achieve stable, fast and relatively safe air heating. Compared with traditional electric heating wire heating methods, PTC electric heaters have more advantages in temperature control, safety protection and long-term operation stability. They are suitable for use in hospital purification projects, clean rooms, fresh air units, air conditioning units and industrial air treatment equipment.

Main features

PTC heating element

Using PTC ceramic heating element, the heating speed is fast and the heating is stable. It is suitable for air heating, auxiliary heating and equipment supporting use.

Self-limiting temperature properties

PTC material has certain self-limiting properties. When the temperature rises, the power will automatically change, which helps to reduce the risk of overheating and improve the safety of use.

High heating efficiency

The heating element and the heat dissipation structure are reasonably coordinated, which can quickly transfer heat to the flowing air and improve the air heating efficiency.

Safe and reliable operation

Thermostat, overheating protection, fuse protection, wind pressure interlock or other safety protection devices can be configured according to customer needs to improve the safety of system operation.

Suitable for air treatment systems

Can be used in fresh air units, air conditioning boxes, air duct systems, clean room air supply systems, industrial hot air equipment and other air heating equipment.

Compact structure and easy installation

The product structure is reasonably designed and can be customized according to the equipment space and air duct size, making it easy to install inside the unit, in the air duct section or in the equipment supporting position.

Flexible control methods

Manual control, automatic temperature control, hierarchical control, thyristor power adjustment, PLC linkage or building automation system interface can be configured according to project needs.

Support non-standard customization

Can be customized according to customer's power, voltage, air volume, installation size, usage environment and project drawings to meet the needs of different countries and different engineering projects.
