L&K Lengku Unveils the K505 Rooftop Integrated Air Conditioner: Next-Level Cooling for Commercial & Recreational Vehicles
L&K Lengku New Energy is proud to announce the launch of the K505 Top-Mounted Integrated Air Conditioner, a high-performance, frequency-convertible cooling solution built for heavy-duty trucks, RVs, and commercial vehicles. Combining robust cooling power, smart efficiency, and durable construction, the K505 sets a new standard for reliable mobile climate control.
Engineered for Power & Efficiency
At the core of the K505 is an intelligent frequency conversion system, designed to balance cooling performance with energy savings. With a refrigerating output range of 800–2400W and adjustable rated power between 400–1000W, the unit adapts seamlessly to varying conditions—from sweltering summer heat to mild climates—delivering consistent comfort without overloading the vehicle’s electrical system. The 24V DC power system ensures compatibility with most heavy-duty vehicle setups, while its 30–50A rated current range supports stable operation.
Compact, Space-Saving Design
The K505’s streamlined footprint makes it ideal for both new builds and retrofits:
- External dimensions: 800 × 894 × 170mm (80 × 89.4 × 17cm)
- Interior panel size: 567 × 262mm, with a low-profile design to preserve cabin headroom
- Total weight: 34.6kg, engineered to add minimal load to the vehicle roof
- Packaging size: 935 × 800 × 220mm (93.5 × 80 × 22cm), optimized for easy shipping and handling
Pre-charged with 600g of R134a refrigerant, the unit is ready for installation straight out of the box, eliminating the need for on-site charging.
Built for Durability & Safety
The K505 is packed with features to ensure long-term reliability, even in harsh operating environments:
- Undervoltage protection: Activates at 21.5V to safeguard the vehicle’s battery
- Undervoltage recovery: Automatically restarts at 25V once power is restored, preventing unexpected shutdowns
- High air volume: Adjustable airflow of 250–450 m³/h, ensuring rapid, even cooling across the cabin
- Weather-resistant construction: Built to withstand extreme temperatures, vibration, and moisture, with a durable white ABS exterior shell
Smart, User-Friendly Operation
Designed for driver convenience, the K505 features intuitive controls and quiet, vibration-free operation. The intelligent frequency conversion system not only reduces noise but also extends the unit’s service life, making it ideal for overnight rest breaks and long-haul journeys alike.
“With the K505, we set out to create a rooftop AC that works as hard as our customers do,” said a spokesperson for L&K Lengku New Energy. “It’s powerful enough to cool large cabins, efficient enough to run on battery power, and built to handle the toughest road conditions—all in a compact, easy-to-install package.”
Backed by L&K Lengku’s commitment to quality and customer support, the K505 is now available for order. For fleet operators, RV builders, and heavy-duty drivers, the K505 offers a reliable, high-performance cooling solution that keeps comfort top of mind, no matter where the road leads.
