Product Description
Using PTC heating technology, PTC coolant heater has good characteristics of self-control temperature, self-constant temperature, and self-energy saving.
PTC thermistor has constant temperature heating, long natural life, energy saving, no open flame, good safety performance, and easy control of heat generation. Application: PTC heater products are mainly used in new energy electric vehicle air conditioning, automobile air conditioning.
Characteristics Of PTC Electric Heaters
1. Constant temperature heating: PTC electric heaters have a constant temperature heating function, it can effectively save energy, reduce power consumption, and is more energy-saving than traditional heaters. Also, it can maintain a constant temperature during the heating process, which avoids excessive temperature rise or fluctuation, so as to ensure a stable and comfortable heating effect.
2. High Safety Performance: PTC electric heaters do not need to use an open flame, they are safer than traditional electric heaters. It can avoid the danger of open flames and electric shock, which can better ensure the safety of users. It also has overheat protection, which can automatically shut off the heating function when the temperature is too high, further enhancing its safety performance.
3. Easy to Control: PTC electric heaters can be easily controlled by a thermostat. Users can set the heating temperature as needed. When the set temperature is reached, it can stop heating automatically to avoid unnecessary energy waste.
