NEWBASE Refrigerated Truck Cooling Unit Excels in -30°C Extreme Test

In the cold chain logistics industry, the performance of a refrigerated truck’s cooling unit is critical—it directly impacts the safety and quality of transported goods. Especially under extreme cold conditions, the reliability and efficiency of the refrigeration system are put to the ultimate test. So, how robust can a refrigerated truck’s cooling system truly be? NEWBASE recently conducted a rigorous real-world test in an environment as low as -30°C, demonstrating the outstanding capability of its all-electric refrigerated vehicle.

The test was carried out in an extreme cold region where temperatures consistently remain around -30°C. This harsh environment was selected to thoroughly evaluate the performance of NEWBASE's proprietary cooling system. The team deployed a brand-new NEWBASE electric refrigerated truck equipped with an intelligent temperature-control system known for its high efficiency and energy-saving operation.

Prior to the test, the vehicle underwent comprehensive inspection and calibration. The battery was fully charged, all cooling unit components were verified to be operational, and the cargo compartment was confirmed to be fully sealed. Multiple temperature sensors were placed inside the container to monitor real-time temperature data, which was transmitted to a centralized monitoring system for precise tracking.

At the start of the test, the internal temperature of the container was nearly the same as the external environment, approximately -30°C. The cooling unit was activated with a target temperature set at +2°C. Immediately, the compressor started operating smoothly, and a steady flow of chilled air circulated throughout the container.

Within the first several minutes, the temperature did not change significantly—this is normal as the air and any simulated cargo gradually absorb the cooling effect. However, after just 15 minutes of operation, the temperature began to drop steadily. The system demonstrated high cooling efficiency, rapidly removing heat from the container while operating quietly and without vibration—a testament to NEWBASE’s advanced engineering and high-quality components.

Moreover, the system’s energy consumption remained well within expected limits, ensuring sufficient battery endurance for long-distance transport even under full cooling load.

Once the interior temperature approached the target of +2°C, the cooling unit automatically switched to an intelligent temperature-control mode. In this mode, the system makes fine adjustments to compressor frequency and cooling output to maintain a stable temperature, even when faced with disturbances.

To test system responsiveness, the container door was deliberately opened briefly, allowing cold ambient air to enter. After closing, the cooling unit immediately adapted—reducing cooling output as the temperature dipped, then increasing it as the container warmed back toward the setpoint. Throughout the test, temperature fluctuations were minimal, ensuring an ideal preservation environment for sensitive goods such as pharmaceuticals and fresh foods.

Further tests simulated challenging transport scenarios, including uphill driving with increased engine load and prolonged continuous operation. Despite increased power demand during incline tests, the all-electric powertrain intelligently distributed energy to ensure uninterrupted cooling performance. During extended operation, the system ran for hours without fault or overheating, confirming its reliability and durability under strenuous conditions.

The test also evaluated performance across different cargo types: pharmaceuticals, fresh food, and flowers. For pharmaceuticals—which require strict temperature control—the system maintained a stable, compliant environment. For fresh goods, both temperature and humidity were well-regulated, preventing dehydration or spoilage. Even delicate flowers arrived in excellent condition, supported by precise temperature management and light-protective measures during transit.

According to industry reports, the global cold chain logistics market continues to grow, driven by rising demand for temperature-sensitive goods and stricter quality regulations. Innovations in energy-efficient and low-emission transport solutions—such as all-electric refrigeration systems—are becoming essential for sustainable logistics. NEWBASE’s system not only meets these demands but exceeds them, performing reliably in conditions where many conventional systems might struggle.

NEWBASE’s electric refrigerated truck has proven its exceptional capability in one of the most challenging cold environments on earth. With rapid cooling, precise temperature control, strong environmental adaptability, and versatile cargo compatibility, it offers a reliable and efficient solution for modern cold chain logistics. As companies increasingly seek sustainable and high-performance transport options, NEWBASE stands ready to deliver innovation on every journey.
