PTC (Positive Temperature Coefficient) heaters are widely used in HVAC (Heating, Ventilation, and Air Conditioning) systems due to their efficiency and safety features. Made from materials like barium titanate ceramic, PTC heaters have a resistance that increases with temperature, allowing them to self-regulate without additional control circuits, preventing overheating.
They quickly heat air and are used for space heating, supplementary heating, or defrosting. By integrating with thermostats and sensors, PTC heaters achieve precise temperature control, reduce energy consumption, and extend equipment lifespan. Although the initial cost is higher, their safety, reliability, and low maintenance needs make them an ideal choice for modern HVAC systems. PTC heaters have a low power density and may require larger equipment to meet specific heating needs.
