KLC PTC heater

EV bus heater failed at –18°C. Root cause: inrush current on cold start, no passive protection.
PTC heaters don't have this problem.
Resistance spikes at Curie point → current self-limits → no runaway.
Physics, not firmware.

Does your heater need to touch metal? Then you need the "D" Type! 🛡️⚡

When designing for electric vehicles or high-moisture appliances (like dishwashers or dryers), standard heaters can be a liability. KLC’s Double-Insulated (D-Type) PTC Heaters are engineered for "Zero-Risk" integration.

Key Benefits of D-Type:
✅ Electrically Insulated Fins: Safe to contact metal frames and conductive materials.
✅ High Humidity Resilience: The go-to choice for bathroom warmers and sterilization cabinets.
✅ Superior Stability: Enhanced shock resistance, ideal for the vibrations of EV and HEV platforms.

Example: Our MH-2110S-93D model ensures that even at high voltages, your chassis remains safe. While it may offer slightly less power than the non-insulated version, the peace of mind for your Quality and Legal teams is priceless.

Is Your Heater Tough Enough for Your Lab’s Cold Storage?

Many "flexible" heaters seem fine on the bench, but fail when subjected to real-world extremes. For medical lab equipment, high-vacuum chambers, or aerospace prototypes, material failure is not an option.

Our PI (Polyimide) Flexible Heaters are built to survive what others can't:
✅ Temp Range: An incredible –250°C to 250°C operating window.
✅ Performance: Maintains flexibility and precise resistance even at cryogenic temperatures.
✅ Customization: Fully customizable shapes to wrap around cryo-vials or vacuum pumps.

Whether you are preventing ice buildup on a satellite antenna or maintaining precise sample temperature in a lab, trust the material that survives the extreme.

Why Your PTC heater's Wattage Isn't Fixed?

Are you struggling with inconsistent heat in your latest prototype? The culprit might not be the heater—it might be your airflow.

The PTC Paradox:
PTC heaters are smart. They "throttle down" to prevent overheating. But if your airflow isn't hitting that sweet spot (usually 6.4 m/s), you aren't getting the power you paid for.

✅ The Fix: Match your fan’s static pressure curve to the heater’s fin pitch.
✅ The Advantage: Our PTC Air Heaters come in multiple fin configurations (1.2mm to 2.6mm pitch) to balance heat transfer vs. air resistance.

Whether you are working on a 48V Industrial unit or an 800V EV battery warmer, we have the technical data to help you select the right fit the first time.

What is an EV HVAC PTC Heater?

In Electric Vehicles (EVs), there is no engine waste heat available to warm the cabin. That’s why many EV HVAC systems use PTC heaters (Positive Temperature Coefficient heaters).

A PTC heater is a self-regulating electric heater that automatically adjusts its power output as temperature rises, ensuring safe and stable heating performance.

Key advantages
• Fast cabin heating
• Self-regulating temperature control
• High safety and reliability

Today, PTC heaters are widely used in EVs, electric buses, and electric trucks to provide efficient cabin heating and improved passenger comfort.

什麼是 EV HVAC PTC 加熱器 (EV HVAC PTC Heater)？

在 電動車 (Electric Vehicle, EV) 中，由於沒有引擎廢熱可利用，因此車艙暖氣通常需要透過 PTC 加熱器 (Positive Temperature Coefficient Heater) 來提供熱源。

PTC 加熱器是一種 自我溫控的電加熱裝置，其材料在溫度升高時電阻會增加，能自動調節電流與熱輸出，確保穩定且安全的加熱效果。

主要優勢
• 車艙快速加熱
• 自動溫度調節
• 高安全性與高可靠度

目前 PTC 加熱器廣泛應用於電動車、電動巴士與電動卡車 的 HVAC 空調系統中，以提供高效率的車艙加熱與舒適的乘坐體驗。

Why 800V Isn't the Ceiling: Engineering the STW High-Voltage PTC Heater

In the race for faster charging and longer range, EV architectures are pushing voltage boundaries like never before. But for thermal management engineers, higher voltage often means higher risks.

At KLC, we didn’t want to just follow the 400V/800V trend. We engineered the STW Type High Voltage PTC Air Heater to be a "set-it-and-forget-it" solution for the most demanding environments.

What makes the STW Series a standout in our High-Voltage Lineup?

⚡ Unrivaled Range: While industry standards often peak at 600V, our STW ceramics remain stable from 3V up to 999V (AC/DC).
🛡️ The Dual-Layer Safety: We’ve integrated an internal safety fuse alongside the PTC material’s natural self-regulation. If a surge occurs or a fan fails, the STW responds physically to prevent thermal runaway.
🌊 IP68 Resilience: Fully encapsulated for real-world automotive HVAC conditions—waterproof, dustproof, and vibration-resistant.
📊 15-20% Higher Efficiency: Our high-surface-area aluminum fins ensure faster cabin warm-up with significantly lower energy draw.

Engineering is about trust. Every STW unit is a product of our ISO 9001:2015 commitment and decades of niche expertise.
