Successful case of Semi truck cab air conditioner




The direct lithium battery integration delivers consistent cooling performance while supporting fleet compliance with stringent anti-idle regulations across North America and Europe. By decoupling cabin climate control from the propulsion engine, Corunclima’s solution extends engine life and lowers maintenance requirements. Early adopters report substantial fuel savings and improved driver satisfaction, addressing two critical challenges in long-haul operations.
Corunclima’s technology represents a growing trend toward electrification of auxiliary systems in commercial vehicles. With no compromise on cooling capacity and seamless integration with existing fleet electrical architectures, the system offers a practical pathway to lower emissions today. As anti-idle laws become more widespread, Corunclima’s lithium-direct solution positions long-haul fleets for both regulatory compliance and operational efficiency.
Our idle free air conditioner have been installed and approved in USA ,Mexico, Latin America, Australia, etc. More and more fleets choose corun Electric APU for cost-effectiveness.Featuring a high airflow rate of 1000 m³/h, the APU can quickly cool sleeper cabs in extreme heat. Its heavy-duty DC electric scroll compressor is supported by lithium battery packs, enabling 10–12 hours of continuous cooling with zero emissions and near-silent operation.By eliminating engine idling, fleets can reduce fuel costs and comply with anti-idling regulations, all while enhancing driver comfort and safety.
