Positive Temperature Coefficient

What are PTC Heaters?

PTC Fan Heaters

OTC PTC Fan Heaters for Electronic Enclosures Positive Temperature Coefficient heaters are becoming increasingly common in the military, industrial, commercial, and home applications. The unique characteristics of rapid heating and maximum temperature with little or no control circuitry provide efficient heating.

PTC Element Cartridge Heaters

New PTC ceramic heating elements improve the efficiency of typical resistive heating elements used in immersible applications where optimal heat transfer is required.

The PTC, Positive Temperature Coefficient, the heating element is built into exceptionally corrosive resistant stainless steel casing.  Unlike the picture of a resistive element without protective casing.

The compact & robust circular provides 360° heat transfer.  The PTC functionality is self-regulating and will not overheat.  

Cartridge heaters are often confused with tubular heaters.  A cartridge heater is designed to be inserted into a die or vessel wall by screw mount.    

Tubular heaters can have more complex geometries and may be welded or permanently attached or clamped to a vessel requiring heating.  

Both types of heaters usually contain electrical resistance heating elements insulated from the surface of the heater.  PTC ceramic heating elements are self-limiting and voltage self-insulating, providing more efficient heat transfer.

PTC Element Fan Heating

PTC ceramic heating elements improve the efficiency of typical resistive heating elements used in applications where electrical forced-air heating is required. The PTC, Positive Temperature Coefficient, the heating element is built into extruded aluminum profiles combined with a fan to effectively transfer heat quickly to an adjoining space.  Aluminum profiles are designed for optimal heat transfer with the forced air across the fins.

Efficient Transfer of Energy

In any heating application, some form of energy, electrical, gas, oil, or even hydropower is being converted into heat.  The energy of one is converted to heat energy which in turn raises the temperature of the adjoining air or physical object to bring both into equilibrium.

A PTC fan heating system converts electrical energy through the resistive element to heat which transfers very effectively to the aluminum housing.  The aluminum housing is designed to radiate the heat to the air moving across its surfaces.
