The Kookaburra is the most powerful roof-top A/C unit available in Australia. Designed to fit in the sun-roof or a custom-made penetration and can cool the whole cab or just the bunk depending on installation.
The Kookaburra combines the condenser, compressor, and evaporator into a single, streamlined unit, saving space.
Custom-made facias allow for a refined look that blends in with the OEM trim.
The Koala redefines rear-wall mounted A/C units with its slick powder-coated steel shell that can be painted to match the truck colour. The Australian made Koala offers a powerful alternative to the Joey for trucks with limited space or airflow under the cab.
The Possum is a powerful 2kW rear-wall mounted sleeper cab air conditioning unit, designed for trucks requiring high-performance cooling without compromising space.
Built with a hardened, reinforced plastic outer shell, the Possum is engineered for durability in harsh transport conditions while maintaining a clean, modern appearance. Its compact rear-mount design makes it ideal for applications where airflow or chassis space under the cab is limited.
Delivering a strong 2kW cooling capacity, the Possum provides reliable engine-off comfort for long-haul drivers operating in demanding Australian climates.
Key Features
The Possum offers a practical and efficient cooling solution for drivers wanting powerful overnight performance in a compact rear-mounted system.
Coolabah Cooling Solutions are engineered for durability, efficiency and long-term performance in demanding transport environments.
A key feature is the variable compressor speed (1500-4500 RPM), which optimises cooling output while reducing strain on components. This results in:
The system also intelligently manages airflow and refrigerant pressure through:
Coolabah systems utilise LFP (LiFePO4) lithium battery chemistry, purpose-built for the transport industry. Benefits include:
Unlike older lithium technologies, LFP batteries are safer, more stable and better suited to heavy vehicle applications.
Coolabah offers purpose-designed 24V battery systems engineered specifically for transport applications.
These systems provide:
This makes Coolabah ideal for drivers wanting reliable overnight cooling without excessive idling.
“Developing a product fit by design, the Coolabah was born. Supplying the trucking industry with a unit, that produces virtually no noise, is lighter and smaller, runs for more than one night on one battery charge, but still powerful enough to cool in the hottest Australian temperatures, was the first priority for the development of the Coolabah”
Coolabah sleeper cab cooling systems run on advanced lithium battery technology, allowing drivers to enjoy powerful air conditioning without running the truck engine. This eliminates unnecessary idling, reduces fuel consumption and provides reliable cooling during rest periods.
Coolabah systems are designed to operate extremely quietly, helping drivers achieve a better night’s sleep while parked. With significantly lower noise levels than traditional diesel-powered systems, drivers can enjoy a peaceful and comfortable cabin environment.
Designed and engineered for Australia’s harsh climate, Coolabah units deliver reliable cooling performance even during extreme summer temperatures. These systems are trusted by trucking companies across the country for their durability and efficiency.
Coolabah systems use advanced lithium battery solutions that recharge while you drive. Depending on the battery configuration, systems can run for many hours — often overnight or up to a full day — ensuring consistent comfort for long-haul drivers.
Because the system runs independently of the truck’s engine, drivers no longer need to idle their truck overnight. This dramatically reduces fuel usage, engine wear and maintenance costs while improving overall fleet efficiency.
As an authorised Coolabah sales and service agent, Auto Comfort provides expert installation, diagnostics, servicing and warranty support. Our experienced technicians ensure your system is installed correctly for maximum performance and long-term reliability.
Yes. Coolabah systems can be configured with different battery capacities, allowing drivers to extend cooling runtime depending on their usage requirements.
