Heater evaporator PTC screw

Self-regulating heaters are based on PTC thermistors. A characteristic feature of PTC heaters is the variable (self-regulating) resistance depending on the heat absorption (operating temperature). The better the heat is absorbed from the heater's surface, the higher the power the element will achieve. In the case of small heat absorption from the heater's surface, the heating element will work with minimal power. PTC heaters are most commonly used in condensate evaporation tanks/trays in cooling devices. The maximum power the heater achieves is in water with a temperature close to 0°C. Then the power drops to about 80-90% of the maximum power when immersed in water at a temperature close to 90-100°C - it reaches nominal power. After the condensate has evaporated, when the heater is already working without contact with water (in air), the element draws about 10% of the maximum power. Since the resistance of the heater changes smoothly, the above percentage data are approximate. The offered heater does not require installation in the wall of the tank/tray and is intended for free placement on the bottom. Hexagonal heads prevent the heater from moving and insulate the bottom of the tank from the heater's jacket (heating part). Self-regulating heating elements with metal heads are intended for use in both metal and plastic tanks. On special order, hexagonal heads can be made of metal.
