Life on the road is demanding. Long driving hours, extreme outdoor temperatures, and overnight parking conditions can quickly turn a truck cabin into an uncomfortable space. That’s why professional drivers need an air conditioning system that is not only powerful, but also efficient, quiet, and reliable.

The Colku V28 24V DC Rooftop Air Conditioner is designed specifically for modern truck cabins, combining high-performance cooling technology with intelligent energy management and a sleek rooftop structure. From intense summer heat to overnight parking comfort, the V28 delivers a premium cooling experience wherever the journey takes you.

More Than Cooling — A Smarter Cabin Comfort System

Unlike conventional truck air conditioners, the Colku V28 is engineered as a complete cabin climate solution.

At its core is a high-efficiency twin-rotor compressor paired with dual brushless fans and a powerful airflow system. Together, these components create faster cooling, smoother airflow, and quieter operation while reducing energy consumption.

The result is a more comfortable cabin environment with less battery drain and better long-term reliability.

Designed to Perform in Extreme Conditions

Truck drivers often operate in some of the harshest environments imaginable — direct sunlight, high humidity, desert heat, and long idle parking periods.

The Colku V28 is built to handle it all.

With a working temperature range from 16°C to 55°C, the V28 maintains stable cooling performance even in extreme outdoor conditions. Whether parked at a logistics station during midday heat or resting overnight after a long route, the system continues delivering dependable comfort.

Fast Cooling with Powerful Airflow

Cooling power means nothing without proper airflow distribution.

That’s why the V28 features a 450m³/h high-airflow evaporator system combined with an electric 3D air distribution design. This intelligent airflow structure helps circulate cool air quickly and evenly throughout the cabin.

What Drivers Experience:

• Faster temperature reduction
• More balanced airflow
• Reduced hot spots inside the cabin
• Improved comfort during sleep and rest

Instead of concentrated cold air blowing in one direction, the V28 creates a more natural and comfortable cooling environment.

Energy Efficiency That Matters on the Road

Parking air conditioners must balance cooling performance with battery protection.

The Colku V28 achieves this with an impressive COP rating of 3.6, delivering strong cooling output while optimizing energy consumption.

This high-efficiency design helps:

• Extend parking runtime
• Reduce electrical load
• Improve battery efficiency
• Lower overall operating costs

For long-haul drivers, this means more reliable overnight cooling without unnecessary power waste.

Quiet Operation for Better Rest

Comfort is not only about temperature — noise matters too.

The V28 uses:

• Twin-rotor compressor technology
• Dual brushless cooling fans
• Optimized airflow channels

Together, these technologies reduce vibration and operating noise significantly compared to traditional rooftop air conditioners.

This quieter operation creates a more relaxing cabin atmosphere, especially important during overnight parking and sleep periods.

Aerodynamic Rooftop Design

The Colku V28 features a streamlined rooftop profile that not only looks modern but also improves aerodynamic performance.

Design Advantages:

• Reduced wind resistance
• Enhanced rooftop durability
• Compact integrated appearance
• Long-term weather resistance

Its robust housing is specifically engineered for mobile commercial vehicle applications and long-term outdoor exposure.

Easy Installation for Commercial Vehicles

The V28 is designed for convenient rooftop integration and supports standard 350mm × 345mm rooftop vent openings, making installation easier across a wide range of truck models.

Suitable for:

• Heavy-duty trucks
• Sleeper cabins
• Logistics vehicles
• Commercial transportation fleets

With a net weight of only 31.5kg, the system also minimizes rooftop load while maintaining structural durability.

Smart Control at Your Fingertips

The Colku V28 includes an intelligent control system with five operating modes, allowing drivers to adjust cooling performance according to real-time needs.

Users can control the system through:

• Mobile App
• Remote controller

Smart Features Include:

• Temperature adjustment
• Mode switching
• Intelligent cooling management
• User-friendly operation

The adjustable temperature range from 15°C to 30°C ensures personalized comfort for every driving condition.

Environmentally Friendly Refrigerant Technology

The V28 uses modern R410A refrigerant, delivering efficient refrigeration performance while meeting current environmental standards.

For customers seeking similar R410A parking air conditioner solutions, Colku also offers the popular D40 rooftop air conditioner series.
