NF Bus Defroster High Voltage Electric Defroster
Description
1. Product Overview
The PTC (Positive Temperature Coefficient) electric defroster is an innovative frost removal device specifically developed for electric buses. Utilizing ceramic heating elements with positive temperature coefficient characteristics, it provides a safe and efficient defrosting solution for vehicle air conditioning systems. The product is directly integrated into the vehicle's high-voltage electrical system (300-750V), perfectly matching the requirements of electric bus platforms.
2. What Makes Our Defroster Special
1) Smart, Self-Adjusting Heat
We use high-quality barium titanate ceramic PTC elements that gently and naturally regulate their own temperature—staying comfortably within 80–180°C. As the weather changes, the system quietly adapts its heating power, so you always get just the right amount of warmth—no guesswork, no over-heating.
2) Efficient, Thoughtful Heating
It warms up to operating temperature in under 3 minutes—and gets the job done faster and more efficiently than traditional heaters. In fact, it clears frost 35% more effectively while using 20–30% less energy—helping your vehicle run smarter and greener.
3) Built-in Care & Protection
Your safety is our priority. That’s why every unit includes automatic protection against overcurrent, overheating, and short circuits. It’s also IP67-rated for dust and water resistance, and rigorously tested for high-voltage safety (over 3,000 V insulation)—so it works reliably, day after day.
3. What’s Inside & How It Fits
1) Key Components
A compact, well-integrated set: PTC heating module, high-voltage relay assembly, intelligent control unit with CAN bus connectivity, and a group of precision temperature sensors—all designed to work together seamlessly.
2) Flexible Installation Options
Most customers choose the evaporator-integrated version (a clean, space-saving fit). If your vehicle design calls for something different, we also offer an independent air duct option—just let us know, and we’ll help you find the best solution.
