DEFU AC 12V 24V Truck Car Evaporators（Cooling Only）-500 507 600 730

1. Superior Heat Exchange Performance from Optional Cores
Aluminum Evaporator Core
Crafted from premium aluminum material, this core is lightweight and boasts excellent thermal conductivity. It responds quickly to realize fast cooling after startup, and maintains stable heat exchange efficiency during continuous operation. With cost-effective design and reliable basic performance, it is the practical choice for regular RV travel and standard working environments.
Full Copper Evaporator Core
The full copper core features remarkable high temperature resistance, oxidation resistance and corrosion resistance. It can operate steadily for a long time under harsh conditions such as high temperature, high humidity and dusty surroundings. It maintains consistent cooling efficiency without performance degradation over time, greatly extending the overall service life of the evaporator.
2. Reliable Operation with Diverse Motor Options
Brushless Motor
Adopting advanced brushless structure, this motor eliminates carbon brush wear. It runs with low noise and slight vibration, and has an extremely low failure rate. It supports long-hour continuous running and frequent start-stop cycles. Nearly no daily maintenance is required, which effectively reduces later operation and maintenance costs for users.
Pure Copper Dual Motor
The upgraded pure copper dual motor works synchronously to generate strong and even airflow. It provides powerful cooling capacity even under heavy load conditions. This structure effectively prevents weak air output and insufficient cooling caused by motor overload, perfectly adapting to long-distance travel and high-intensity continuous use.
3. Optimized Rooftop Structure & Practicality
Adopting integrated rooftop design, the evaporator has a compact overall size and will not occupy the interior space of RV. The simplified structure enables easy and quick installation without complex pipeline layout. The reinforced body structure has great vibration and shock resistance, ensuring stable operation during bumpy driving on various road conditions.
4. Professional Single-Cooling Performance
Focused on refrigeration function, this evaporator is tuned to deliver outstanding cooling effect in hot weather. All matched components work in coordination to create a cool and comfortable indoor environment inside the RV. Every unit undergoes strict quality testing to guarantee stable performance and strong adaptability for all kinds of outdoor travel scenarios.

We provide four mainstream evaporator models including 500, 507, 600 and 730, forming a complete performance gradient from economical entry-level to high-power heavy-duty. All series are cooling-only rooftop evaporators with mature fin-and-tube structure, universal RV rooftop installation size, and compatible dual-core and dual-motor configurations. Customers can select the optimal model according to RV interior space, vehicle size and cooling demand.
1. 500 Model | Economical & Compact Entry-Level Choice
The 500 evaporator is a classic compact entry-level model, designed for small RVs and mini recreational vehicles with limited installation space. It features ultra-compact body size, lightweight design and easy embedded rooftop installation, without squeezing indoor activity space. Adopting optimized basic heat exchange structure, it delivers stable and energy-saving cooling performance, fully meeting daily short-distance travel and urban camping cooling needs. With high cost performance and low failure rate, it is the preferred economical replacement part for light-duty RV air conditioning systems.
2. 507 Model | Balanced Performance & Best-Selling Universal Model
507 L-type large 4-hole evaporator is our core mainstream model with balanced performance and wide compatibility. Equipped with 28-tube fin type heat exchange structure and 3800 kcal/h stable cooling capacity, it takes the lead in cooling speed and air supply uniformity. The customized large 4-hole air outlet covers a wider indoor area, solving the problem of local temperature imbalance. Supporting dual core and dual motor free matching, it adapts to most medium-sized RVs and all outdoor camping scenarios. It balances economy, cooling power and durability, becoming the most versatile and cost-effective model in the series.
3. 600 Model | High Air Volume & Enhanced Cooling Version
The 600 evaporator is an upgraded enhanced model based on the 507 version, focusing on upgrading circulating air volume and heat exchange efficiency. It optimizes the internal fin and tube arrangement, with larger effective heat exchange area and stronger air circulation capacity. Compared with conventional models, it realizes faster temperature drop and more uniform three-dimensional cooling. Suitable for medium and large RVs with slightly larger indoor space and higher cooling requirements, it maintains stable high-efficiency cooling during long-time high-temperature operation, with better heat dissipation and anti-overload performance.
4 .730 Model | Heavy-Duty High-Power Super Cooling Version
730 evaporator is a heavy-duty high-power flagship model, tailored for large RVs, extended RVs and luxury camping vehicles with large indoor space. It adopts an upgraded reinforced heat exchange structure with enlarged overall specification size, realizing maximum circulating air volume and ultra-strong cooling output. It can quickly cool down large-space carriages and maintain constant low temperature in high-temperature and sultry outdoor environments for a long time. Equipped with high-load resistant pure copper dual motor matching, it supports 24-hour uninterrupted heavy-duty operation, features strong vibration resistance and extreme weather adaptability, and is the first choice for high-intensity and large-space RV cooling scenarios.
