Specific Applications and Brand Examples:
Brands: Daikin, Mitsubishi Electric, Panasonic, Gree, Midea (select premium series).
Purpose: Activates in extremely low outdoor temperatures to supplement the heat pump, rapidly increasing the outlet air temperature. This addresses the common weakness of "poor heating performance in winter." The fire-spark and overheat prevention characteristics of Aluminum PTC elements make them ideally suited for installation inside fan units.

Brands: Dyson, Balmuda, Airmate, Panasonic.
Purpose: Serves as the core heating element directly. For instance, certain Dyson fan heaters utilize meticulously designed PTC heating arrays, combined with their airflow technology, to achieve uniform and rapid heating.

Brands: Panasonic, LG, Miele.
Purpose: Heats air to improve dehumidification efficiency or acts as a supplemental heat source in heat pump dryers for faster drying cycles. Their self-regulating temperature property prevents damage to fabrics from overheating.

Brands: Panasonic, Honeywell, Broad, Lanye.
Purpose: In frigid climates, pre-heats the cold, incoming fresh air. This prevents uncomfortable drafts, enhances indoor comfort, and protects the heat exchange core from freezing.
