Combining the characteristics of PTC heating elements and the vulnerability of heating pipe, our engineers designed PTC engine heaters—Titan-B series, after 6 years’ research and development.

Titan-B series have built-in pumps, which largely increases the heating efficiency. It is very safe to use this product as PTC is covered by an insulating material (thus PTC is separated from the antifreeze) and the heating elements are strong.

With a rated power of 1200w, Titan-B series can reach the same heating effect generated by Titan-P series with rated powers from 2000w-2500w.

After detailed investigation, we are sure that Titan-B series will lead in the engine heaters markets.

We have applied for the patent in China, and are applying for the patents in Europe and in North America.

PTC ceramic material is named for its positive thermal coefficient of resistance (i.e., resistance increases upon heating). Most ceramics have a negative coefficient, whereas most metals have positive values. While metals do become slightly more resistant at higher temperatures, this class of ceramics (often barium titanate and lead titanate composites) has a highly nonlinear thermal response, so that it becomes extremely resistive above a composition-dependent threshold temperature. This behavior causes the material to act as its own thermostat, since current passes when it is cool, and does not when it is hot. Thin films of this material are used in automotive rear-window defrost heaters, and honeycomb-shaped elements are used in more expensive hair dryers and space heaters.

How ceramic heaters work

PTC ceramic material is semi-conductive and when voltage is applied to it, the power decreases quickly as it reaches a certain temperature according to the particular composition of the ceramic. This means its temperature is self-regulating.

Differences from other electric heaters

Electric heating elements, made of resistance wire also have a positive temperature coefficient of resistivity, but do not increase their resistance enough to be self-regulating; they are typically used with the wires red-hot. The ceramic, on the other hand, increases its resistance sharply at the Curie temperatures of the crystalline components, typically 120 degrees Celsius, and remains below 200 degrees Celsius, providing a significant safety advantage.
