Colku MT26 24V DC Rooftop Parking Air Conditioner - Customized for Medium-Duty Trucks

The 2026 MT26 series includes two differentiated models to cover diverse power demands of light trucks: the MT26 supporting both 12V and 24V power supply, and the dedicated MT26A variant optimized for 12V light trucks. Unlike universal parking air conditioners mainly designed for heavy-duty semi-trailers, the MT26 platform is developed from the ground up around the structural characteristics, power limits and cab space of light-duty trucks, which are widely applied in urban distribution, last-mile delivery, short-distance transportation and regional logistics.

One standout advantage of the MT26 series is its driving & parking dual-scenario compatibility. It can work normally whether the vehicle is travelling on roads or stationary during drivers’ rest time. Drivers no longer need to keep the engine idling to cool the cab while parking, effectively cutting unnecessary fuel waste, lowering carbon emissions and helping fleets comply with increasingly strict environmental and idle restriction regulations worldwide.

Weight control sits at the core of the MT26 design philosophy. Adopting optimized structural layout and high-strength lightweight materials, the rooftop unit achieves remarkable weight reduction compared with conventional parking air conditioners. The lightweight structure reduces extra load on light trucks, helps improve fuel economy during daily operation and avoids overloading risks that trouble many light vehicle owners. Balancing weight, structural rigidity and weather resistance, the unit remains durable under bumpy road conditions, intense sunlight and frequent temperature changes.

To deliver a perfect fit inside light truck cabs, Colku independently develops a special interior trim panel exclusive for light-duty trucks. The interior panel matches the internal space and installation hole positions of mainstream light truck models perfectly. It enables neat, seamless installation without destructive modification to the original cab, creates a tidy visual effect inside the driving compartment, and greatly shortens installation time for service technicians.

In terms of core configuration, the MT26 series is equipped with internal and external full DC brushless fans. DC brushless technology eliminates the defects of traditional brushed fans such as high power consumption, fast wear and unstable airflow. The fans operate with steady air output, high conversion efficiency and extended service life. On top of advanced fan hardware, Colku’s R&D team optimizes internal air duct layout, vibration damping structure and airflow turbulence suppression. The comprehensive optimization realizes effective noise reduction, providing drivers with a quiet rest environment during breaks after long hours of driving. Even under continuous operation, the unit maintains stable refrigeration capacity without sharp performance attenuation under fluctuating voltage.

From an industrial perspective, the rollout of MT26 series marks a crucial strategic layout of Colku in the segmented light-duty truck market. For a long time, most rooftop parking air conditioning products on the global market focus on long-haul heavy trucks. Light truck owners could only choose simplified universal models lacking targeted optimisation, which often suffer poor matching, high energy consumption, loud running noise and difficult installation. The MT26 series responds directly to the unmet market demand for professional light truck climate control products.
