Positive temperature coefficient (PTC) heaters are powerful ceramic heaters ideal for small spaces and containers. Safe, effective, and self-regulating, PTC heaters come in two main designs that maximize airflow for optimal heat dispersion.
Fin PTC Heaters. Fin PTC heaters are so-named for their large aluminum fins, which circulate air across a large surface area for efficient heat transfer. These elements are designed with temperature-limiting effects, which reduce the risk of overheating, making them a safe option for settings ranging from operating rooms to airline interiors.
