Rooftop Parking Cooler We Offer

Your Rooftop Parking Cooler Maker's Capacity

R&D And Innovation
We have an in-house technical center capable of independently handling the entire design process,from circuit control systems to aerodynamic housings.
We have independently developed control algorithms for DC inverter compressors,achieving an extremely high energy efficiency ratio (EER).This ensures sufficient cooling capacity while minimizing power consumption and extending the vehicle’s battery range.
Using fluid simulation software,we have optimized the airflow channels to keep operating noise between 40 and 50 decibels and ensured an ultra-slim profile to reduce aerodynamic drag.
Scalability & Flexible Manufacturing
We have the industrial infrastructure to fulfill large-volume global orders and ensure rapid delivery.
With multiple automated assembly lines,our maximum daily production capacity reaches over a thousand units,ensuring extremely short lead times for large-scale orders (typically 15–30 days for bulk shipments).
We possess in-house capabilities for mold manufacturing,injection molding, and the machining of condensers and evaporators,and we ensure production continuity and stability through a vertically integrated supply chain.
Quality Assurance & Testing
Every air conditioner that leaves our factory undergoes multiple extreme environmental tests to ensure stable operation under harsh conditions.
End-to-End Quality Control:
We strictly adhere to the ISO 9001/IATF 16949 automotive industry quality management system.
We are equipped with a water spray test chamber (for rain resistance testing),a vibration test bench (to simulate bumpy roads),and a high-temperature environmental chamber (to simulate extreme heat ranging from 45°C to 55°C), ensuring our products have a service life of 3 to 5 years or more.
Customization & OEM/ODM
We offer customized solutions tailored to the specific requirements of different regions and vehicle models.
Multi-voltage Compatibility:
We provide a variety of voltage options,including 12V and 24V,to suit trucks,RVs,construction machinery,and specialty vehicles.
We support customization of exterior colors,logo screen printing,and control panel interfaces based on client brand requirements.We don’t just provide products;we offer a one-stop solution from product definition to implementation.

Advantages of Our Rooftop Parking Cooler

We utilize advanced DC inverter technology,powered directly by the vehicle’s battery without the need to start the engine.
In Economy Mode,power consumption is as low as 300–600 W,ensuring the vehicle can remain cool for extended periods even with the engine off.
A built-in intelligent voltage monitoring system automatically shuts down the unit when the battery voltage drops below a preset level,ensuring the vehicle can start normally at any time and eliminating the driver’s range anxiety.

To meet the needs of long-haul drivers for rest at night,we have made significant improvements to our noise-reduction technology.
By optimizing the airflow channel design and using high-performance brushless fans,we have kept operating noise levels between 40 and 45 decibels,providing drivers with a quiet sleeping environment.
The digital inverter compressor automatically adjusts its speed based on the interior temperature, preventing sudden fluctuations and delivering a more consistent and comfortable ambient temperature.

We are committed to reducing installation costs and time for our customers.
Our products are designed to fit most standard sunroof openings,enabling damage-free installation that preserves the roof structure and offers exceptional waterproofing performance.
Available in a variety of specifications,including 12V and 24V,our products are widely used in heavy-duty trucks,light-duty trucks,excavators,cranes,agricultural machinery,and various types of recreational vehicles.

FAQs For Ordering Rooftop Parking Cooler

How To Order Your Rooftop Parking Cooler Products?

To provide you with the most accurate quote and compatibility solution,you will typically need to provide the following information when ordering a rooftop parking cooler:
The rated voltage of your vehicle’s battery system (12V, 24V).
The dimensions of the roof opening (length × width × height in mm).
Whether the roof has reinforcing ribs or a curved profile,as this affects the selection of sealing strips and waterproofing performance.
What is the vehicle type:heavy-duty truck cab (with sleeper),excavator,motorhome,or van?
What is the approximate volume of the interior space requiring cooling in cubic meters?
Does the vehicle primarily operate in temperate or tropical regions?
And do you require a specific color paint job or the addition of your company logo?
If you have any uncertainties,please feel free to contact us at any time.Provide your vehicle information,and our team of experts will recommend the most suitable product for you.

We typically accept payment via wire transfer (T/T),as we believe this is beneficial to both parties and helps save on bank fees.
For larger amounts,we can also accept irrevocable letters of credit (L/C),but a deposit is required in advance,especially for custom-made products.

Of course.We offer sample orders so you can evaluate cooling performance,noise levels,and installation compatibility before placing a bulk order.Once you’re satisfied with our products,you can proceed with a large-volume order.
