PTC Self-regulating cartridge heaters can also be called PTC cartridge heater, because there is PTC elements as the heating elements inside. PTC heating elements are temperature and current self-regulating. Because PTC ceramic element is manufactured to a specific temperature. So once the Cartridge heater reaches that temperature the inverse nature of the device increases resistance in the circuit to infinity effectively shutting down the circuit.  PTC

The temperature is relative to an ambient temperature such that at high ambient temperatures less current flows in the circuit to reach the set-temperature without external controls.  The self-regulating nature protects the device from over-temperature and current.

THE MAIN BENEFITS ARE:
– High performances
– No need of temperature controls
– Energy savings
– Fully hermetic
– Easy, fast assembly
– Excellent mechanic and corrosion resistance

 

PTC element cartridge component converts electrical energy through the resistive element to heat which transfers very effectively to the aluminum housing.  The circular stainless steel housing is designed to transfer heat directly to the surrounding surface or liquid. 

Application field of Self-regulating cartridge heaters:

  • Plastic molding

  • Laminating 

  • Heating gases & liquids

  • Hot stamping

  • Extrusions

  • Packaging equipment

  • Injection molding

  • Sealing

  • Labeling

  • Hot melt adhesives

  • Fluid heating

 

The Positive Temperature Coefficient element controls the resistance of the circuit to a specifically designed point. The warmer the element the higher the resistance.  The cooler the element the lower the resistance and more current will flow increasing the heat. These characteristics save energy and prevent excessive heating losses.
