India’s tropical climate brings year-round mosquito pressure. Many households rely on electronic mosquito repellent heaters to vaporize liquid repellents or heat repellent pads.
However, one Indian consumer electronics brand faced a serious issue with their existing heater design:
The temperature fluctuated too much
Repellent vaporization was inconsistent
Heating coils burned out easily
Overheating created safety concerns
Devices required frequent replacement
Customer complaints increased during summer and monsoon seasons
They needed a small, safe, stable, and low-cost heating solution that could operate every night for long hours.
During their search for a safer heating core, they discovered PTC ceramic heating chips — especially Tiancheng’s:
32 years of PTC experience
High stability for small household appliances
Consistent temperature control at 110–150°C, ideal for vaporizing mosquito liquid
Self-regulating behavior — no risk of overheating
Long lifespan, even under continuous nightly use
Ultra-compact chip size for mini repellents
Strong supply chain reliability
The brand realized that a PTC chip could completely replace the old heating coil, improving both performance and customer experience.
We provided a custom rectangular PTC heating chip, optimized for mosquito repellent devices.
Self-regulating temperature — perfect for stable vaporization
Fast warm-up — reaches target temperature quickly
Long-term stability — consistent heating every night
No burning smell, no overheating
Low power consumption
Safe for indoor, night-long use
Compact size, easy to integrate into very small plastic housings
The chip was positioned inside the device beneath the repellent pad/liquid wick, providing uniform heating with no spikes.
After switching to Tiancheng’s PTC chip, the Indian client reported:
Repellent vaporizes evenly throughout the night
Temperature stays stable in all seasons
Immediate warm-up after switching on
No burnt pads, no overheating incidents
Zero heater burnout failures
Device lifespan increased significantly
Fewer customer complaints
Stronger product reviews and repeat sales
Safer for families and children
No glowing red wires or exposed coils
Silent operation
Lower electricity consumption
This upgrade also helped them expand to major retail channels and online platforms.
PTC technology is ideal for mosquito repellent devices because:
It naturally limits temperature
It consumes only the power needed at each moment
It provides smooth, clean, odor-free heating
It is durable for long-cycle daily use
It improves both performance and safety
Tiancheng’s expertise ensured the client received consistent quality, stable batch-to-batch performance, and customizable temperature ranges matched to their repellent formula.
