PTC Cartridge Heater
PTC cartridge heater can also be called self regulating cartridge heater, Thin rectangular PTC thermistor welded by insulated cable is encapsulated in Metal shell PTC Cartridge heater are suitable for heating applications of pipes, storage tanks, containers, containers and equipment shells. The threaded hex head design is ideal for tank, vessel and pipeline installation and other industrial applications, providing greater shock and vibration resistance. Typical applications such as automotive carburetor heating, water heater, etc.
Advantages of PTC cartridge heater:
Self regulation and safety
PTC heating element can adjust temperature and current automatically. Each PTC ceramic component is manufactured at a specific temperature. Once the device reaches this temperature, the opposite characteristics of the device will increase the resistance in the circuit to infinity, thus effectively closing the circuit.
The temperature is related to the ambient temperature, so in high ambient temperature, the current flowing in the circuit is less, and the set temperature can be reached without external control. The self-adjusting feature protects the equipment from overheating and current.
Straight tube or Threaded Metal housing is available, the dimater and length can be custom made.
Main benefit of PTC cartridge heaters:
– high performance
– no temperature control required
– energy saving
– completely sealed
– simple and fast assembly
– excellent mechanical and corrosion resistance
Specifications of PTC cartridge heater:
Working voltage: 12-24 V
Surface temperature: up to 180C
