220V 600W PTC Heating Element for Rapid Heating and Self-Regulating Temperature

PTC insulated fin air heater - 600 W, 220 V AC or DC, size 280 x 32 x 26 mm. Key benefits - Fast, consistent warm-up: PTC thermistor element and large aluminum fin surface deliver rapid heat transfer into moving air for stable output. - Long service life: Robust construction with aluminum tube and PTC element designed for extended operation. - Low noise operation: Designed for use with forced airflow to provide quiet heating in ducted or fan-assisted systems. - Compact and easy to install: Slim 280 x 32 x 26 mm form factor with 200 mm high-temperature silicone lead simplifies integration into small appliances and HVAC modules. - Self-regulating temperature: The PTC element limits its own temperature within a working range for predictable performance under varying airflow conditions. What it is and how it works This is a PTC insulated fin heater intended to heat moving air. The PTC thermistor element is mounted inside an aluminum tube and insulated from the tube. Aluminum fins increase surface area for uniform heat transfer and adapt to the airflow volume. When air moves across the fins, heat is distributed evenly; the PTC characteristic provides automatic regulation of heating power within its operating range.
