Heater 2PTC 240W 230V

Self-regulating heaters are built on the basis of a thermistor PTC. A characteristic feature of PTC heaters is the variable (self-regulating) resistance depending on the heat output (operating temperature). The better the heat transfer from the surface of the heater, the higher power the element will achieve. In the case of low heat transfer from the surface of the heater, the heating element will operate at minimal power.

PTC heaters are most commonly used in evaporation tanks/trays for condensate in refrigeration devices. The maximum power of the heater is achieved in water at a temperature close to 0°C. Then, the power drops to about 80-90% of the maximum power when submerged in water at a temperature close to 90-100°C - reaching nominal power. After the condensate evaporates, when the heater operates without contact with water (in the air), the element draws about 10% of the maximum power. Since the resistance of the heater changes smoothly, the above percentage data is indicative.

The offered heater does not require installation in the wall of the tank/tray and is designed for free placement on the bottom. Hexagonal heads prevent the heater from moving and insulate the bottom of the tank from the heater's casing (heating part). Self-regulating heating elements with metal heads are designed to work in both metal and plastic tanks. Upon special request, hexagonal heads can be made of metal.
