Description

This PTC air heater utilizes a Positive Temperature Coefficient ceramic element housed within an aluminum shell. The PTC material provides inherent self-regulation, limiting its maximum surface temperature and preventing overheating, which makes it suitable for sustained dry heating cycles without external control circuits.

The aluminum construction ensures effective thermal conduction and mechanical robustness. With a 12V DC operating voltage and 30W power rating, it is compatible with common DC power supplies and battery systems, facilitating integration into portable or fixed heating assemblies for air flow applications.

Key Features

  • Self-Regulating PTC Core: Provides a constant surface temperature, enhancing operational safety and simplifying thermal management.
  • Durable Aluminum Housing: Offers excellent heat transfer and a sturdy, long-lasting mechanical structure.
  • Dry Heating Capability: Engineered for reliable, long-duration operation in air heating environments without liquid cooling.
  • High-Temperature Silicone Leads: Ensure wiring integrity and insulation at elevated operating temperatures.
  • Compact Form Factor: The slim 5mm profile and small footprint allow for integration into space-constrained designs.
  • Optimized Performance-to-Cost Ratio: Delivers reliable heating functionality in a high-value, industrially relevant package.

Applications

  • Compact air flow heaters for instrumentation dehumidification cabinets.
  • Component preheating stages in automotive diagnostic or repair equipment.
  • Custom-built hair styling tools like travel dryers or curler heating elements.
  • Air heating modules for DIY climate-controlled enclosures or incubators.
  • Auxiliary heating elements in portable consumer appliances requiring safe, regulated heat.

Frequently Asked Questions

What is the operating voltage and power consumption of this PTC heater?

This heater is designed for 12 Volts DC operation and has a rated power of 30 Watts. Ensure your DC power supply can deliver at least 2.5 Amps (30W / 12V) to operate it correctly. Exceeding the 12V rating can damage the element.

Can this PTC element be used for liquid heating or submerged in water?

No, this specific model is described for dry air heating applications. Its construction and insulation are not designed for direct liquid immersion or submersion. Using it in liquid could cause electrical failure or pose a safety hazard.

How do I connect and mount this heater?

Connect the silicone-insulated lead wires to a 12V DC power source, observing polarity if applicable (typically not critical for resistive heaters). The flat aluminum body can be mounted using thermal adhesive, clamps, or screws (taking care not to short the leads) to a heatsink or air duct for efficient heat transfer.

Does this heater require a separate thermostat or temperature controller?

The PTC (Positive Temperature Coefficient) material is self-regulating. Its resistance increases sharply above a certain temperature, naturally limiting its heat output and stabilizing its surface temperature. For basic applications, an external controller is not strictly necessary, but one can be added for precise setpoint control.
