PTC Air Heater

Self-regulating PTC air heaters for fast, stable and reliable air heating.

Including

Forced-air PTC heater
Convection PTC heater

A PTC air heater is a heating assembly that uses self-regulating PTC ceramic elements paired with metal fins to heat moving or still air. As the ceramic element approaches its operating temperature, its electrical resistance increases, helping regulate power output and provide a stable heating characteristic.

As a PTC air heater manufacturer, PTCWORKS supplies two primary airflow configurations: forced-air and convection. The right configuration depends mainly on the required heating speed, airflow conditions, available installation space and system design.

Type	Airflow	Best For
Forced-Air PTC Heater	Paired with a fan or blower for directional airflow	Fast, directional heat delivery such as defrost, defog and rapid cabin warm-up
Convection PTC Heater	Relies on natural airflow without a dedicated fan	Quiet, passive heating for enclosures and cabinets where fan noise or additional power draw is undesirable

About PTC Air Heaters

What It Is

A PTC air heater combines PTC ceramic heating elements with metal fins to transfer heat into moving or still air. Forced-air configurations work with a fan for faster heat delivery, while convection configurations use natural airflow for quiet, passive heating.

Product Uses

Dryers and industrial air curtains
Enclosure and cabinet heating

How to Customize

Forced-air vs convection airflow
Fin spacing and stack size
Voltage and wattage density

FAQ

PTC Air Heater FAQ

What is a PTC air heater? +

A PTC air heater uses self-regulating PTC ceramic heating elements, typically paired with metal fins, to transfer heat into moving or still air. As the PTC element heats up, its electrical resistance increases, helping regulate its power output.

Should I choose a forced-air or convection PTC heater? +

Choose a forced-air PTC heater when you need fast, directional heat and a fan or blower fits your system. Defrost, defog and rapid cabin warm-up are typical applications. Choose a convection PTC heater when quiet, passive heating without a dedicated fan is preferred, such as enclosure or cabinet heating.

Can the fin spacing and stack size be customized? +

Yes. Depending on the application, PTC air heater configurations can be customized in areas such as fin spacing, stack size, voltage, wattage density and frame or housing material. Target airflow and installation dimensions can be used to determine a suitable starting configuration.

Does a PTC air heater need a thermostat? +

PTC ceramic heating elements have a self-regulating resistance characteristic that helps limit power as the element temperature increases. Whether an external thermostat or additional temperature-control component is required depends on the complete heating system and its operating requirements.

Do you offer free PTC air heater samples? +

Yes. Send your target airflow, operating voltage and preferred configuration — forced-air or convection — to sales@ptcworks.com and the team can follow up regarding sample availability.
