At the heart of battery APU innovation is a commitment to improving life on the road. High-quality climate control systems are more than mechanical solutions—they represent a dedication to human well-being. By bringing reliable comfort to drivers, these technologies help ensure that the pursuit of efficiency never comes at the expense of health or dignity. This vision aligns with a broader mission: delivering high-quality products that reflect a love for life and a respect for those who keep global supply chains moving. By combining advanced engineering with a human-centered philosophy, battery APUs embody the idea that technology should serve both performance and people.

Amidst the sweeping electrification transformation of the commercial vehicle industry, a previously overlooked corner is undergoing profound change—truck air conditioning and transportation refrigeration systems. While the industry spotlight largely focuses on the power density of drive motors and battery range, a "quiet revolution" concerning the working environment of millions of truck drivers and the future of cold chain logistics is unfolding both inside and outside the cab.

The rise of EV truck refrigeration equipment marks a pivotal step toward greener, smarter cold chain logistics. By combining zero-emission operation, precise temperature control, and reduced operating costs, these systems provide a compelling solution for fleets navigating an increasingly regulated and sustainability-focused market. As technology continues to evolve, electric refrigeration will play a vital role in ensuring safe, efficient, and environmentally responsible transport of temperature-sensitive goods worldwide.

As urban logistics accelerates its entry into the new energy vehicle arena, a long-neglected technological sub-sector is quietly gaining momentum. Recently, several domestic refrigeration equipment companies have released dedicated refrigeration unit solutions for electric vans, marking a profound transformation in the cold chain transportation equipment market from "oil-electric co-operation" to "pure electric dedicated." In the era of traditional fuel-powered trucks, refrigeration units in refrigerated trucks typically relied on the vehicle's engine or an independent diesel engine for power. While the technology was mature, energy consumption and emissions were significant issues. However, with the chassis power shifting from fuel engines to battery packs, simply using the old refrigeration logic can no longer meet the operational needs of new energy commercial vehicles. Industry experts point out that the development challenge of dedicated refrigeration units for electric vans lies not only in "refrigeration efficiency" but also in achieving a delicate balance with limited onboard electrical power.

Corunclima’s V150TB and V350TB models are flagship electric van freezer units capable of maintaining temperatures as low as -20 °C, ideal for transporting frozen foods, ice cream, pharmaceuticals, and other temperature-sensitive cargo that require sub-zero conditions. The units operate entirely on 100% DC electric power, drawing from a vehicle’s battery or integrated lithium-ion power packs, eliminating the need for engine idling and traditional fossil fuel usage.

​A key link in cold chain transportation is undergoing a silent revolution—a shift from traditional diesel-powered systems to all-electric systems. This transformation not only reduces noise and emissions but also profoundly restructures the operational model and industry ecosystem of cold chain logistics.

A key highlight of Corunclima’s portfolio is the C16E and R16E models, which offer 1600 W of cooling capacity for trailers up to approximately 12 m³, capable of producing stable chilled temperatures down to -5 °C and deep-freezing conditions to around -20 °C respectively. Larger units like the C24E/R24E extend this capability up to 2500 W for volumes of up to 25 m³, making them suitable for larger event storage or commercial food transport.

At dawn, an electric heavy truck slowly drives into a logistics park. While waiting to load and unload, the driver turns on the air conditioning. In stark contrast to the roar and vibration of traditional diesel trucks, this vehicle is so quiet it's almost unnoticeable—the electric air conditioning system silently delivers cool air, consuming no fuel and emitting no emissions; only the energy consumption data on the electronic screen flickers slightly.

What sets the K50BS apart is not just its raw cooling power. With a high airflow rate of approximately 1000 m³/h (589 CFM) it rapidly transforms sleeper cabins into comfortable environments even in extreme heat, ensuring drivers can rest properly without idling their engines.

Corunclima’s latest offerings exemplify the practical benefits of this innovation. Their 48V all-electric truck refrigeration units deliver powerful cooling from +25°C down to deep-freeze temperatures around -20°C, all within a compact, plug-and-play package that is quick to install on a wide range of electric trucks. With whisper-quiet operation and compliance with stringent urban noise regulations, these units support night-time deliveries and urban logistics without community disturbance.
