PTC Cartridge Heaters Explained
PTC Cartridge Heaters Components for Equipment Design
PTC cartridge heaters are dynamic heating elements that combine the functions of heating and temperature control in one element.
Cartridge heaters are used when the heat needs to be transferred directly to a material inside a container or vessel. They are inserted through the wall of the vessel or into a hole to reach the material to be heated.
The PSA Series heater is embedded in an aluminum housing providing a strong design and excellent heat transfer characteristics. Each are pre-wired for easy installation.
The series comes in a range of 11W (max) to 113W (max) wattage's depending on the configuration with voltages from12-24V or 110-240V. Surface temperatures range from 176 – 392 degrees F depending on the wattage and size selected.

Positive Temperature Coefficient Cartridge Heaters
PTC ceramic thermistor cartridge heaters are provided in round cylindrical aluminum housings. The safety and dependability of the PTC cartridge heaters and the compact size offers the best option for design engineers.
Durability, reduced repairs, and downtime
The ceramic materials used in PTC heaters are much more durable than typical resistive elements greatly improving the durability and dependability of the components. There is no chance of burned out elements or coils with ceramic heaters.
