[Seeking cooperation] Cold Chain Magic Cube：the era of mobile cold storage

National Development and Reform Commission's "14th Five-Year Plan" for Modern Logistics Development proposes to improve the cold chain source point network, build origin cold chain distribution centers, and optimize the organization of agricultural product collection at the field: explore the development of shared "field stations" and other mobile cold storage facilities to enhance the comprehensive utilization efficiency of cold chain logistics facilities at the origin; construct a number of origin cold chain distribution centers to improve the conditions of public cold storage facilities at the origin; and enhance the efficiency of collecting goods from the field to origin cold storage preservation facilities and mobile cold storage units.

Cold Chain Magic Cube (Shanghai) Technology Co., Ltd., established in 2021, is a subsidiary of China City Industrial Group Co., Ltd. It is a technology company specializing in the R&D, production, sales, and operation of new phase-change cold storage containers. Held by China City Industrial Group Co., Ltd. (formerly CRRC Urban Traffic Co., Ltd.), it is a state-capital-controlled enterprise jointly established by CRRC Group, local state-owned assets in the Yangtze River Delta region, and strategic investors from CHINA CITY INDUSTRIAL GROUP CO., LTD. Supported by the top-tier industrial ecosystem of its parent group, the company has become a leading enterprise in domestic intelligent lifting systems, dedicated vehicles for urban operation and maintenance in 100+ cities, new energy vehicle components, and smart agricultural machinery for listed companies and their subsidiaries.

Traditional cold chain storage consumes high energy, incurs significant electricity costs over long-term operation, relies on manual temperature monitoring and equipment maintenance, and has short preservation times, high water loss rates, poor flexibility, and difficulties in adjusting location and capacity. Initial construction investment is high, and operational costs are substantial. In contrast, phase-change cold storage saves up to 70% in energy consumption compared to traditional refrigeration, enables remote monitoring and automated operation management, and extends the shelf life of various agricultural products. Its mobile storage can be deployed flexibly according to demand, making it suitable for providing customized storage services for high-end single products. Compared to traditional air-cooled containers, it can save 50%-70% in energy. The current core product is the mobile phase-change cold storage container, which uses cold energy released by phase-change materials stored at the top of the container for cold chain transportation. Equipped with an intelligent remote monitoring system, it can alternate

the temperature and humidity inside the container in real time, offering convenience and suitability for various scenarios such as intermodal transport, temporary storage, and emergency supply.

Other product line application solutions:
Fixed Cold Storage Upgrade Solution: Phase-change cold storage modules can be installed on the roof of fixed storage, the top of shelves, or between shelf layers, meeting the needs of upgrading fixed cold storage to phase-change cold storage.
Urban Distribution Solution: Customized solutions for entire warehouses. Phase-change cold storage modules can be installed in various refrigerated vehicle compartments, customized to sizes such as small cold storage units, mobile cold storage units, and refrigerated delivery boxes for express delivery, meeting the upgrade and usage needs of various equipment for urban distribution and the multi-terminal application requirements of the first and last mile.

Self-developed air ducts and circulation fans ensure even distribution of the ripening gas, preventing localized over-ripening or under-ripening. This enables uniform maturation of entire fruit batches, enhancing supply chain efficiency.

Integrated with IoT and sensor technology, the system supports remote real-time monitoring and intelligent alerts, achieving fully automated and intelligent ripening management while significantly reducing labor requirements and improving operational stability.

The following are benchmark cases of phase-change mobile cold storage:Feedback from Nanjing Zhongcai Merchants: A cost-reducing and efficiency-improving product:
Cost Reduction: Phase-change cold storage containers are more cost-effective in the long run compared to traditional cold storage, saving 40-50% overall. Costs such as electricity and rent are reduced, thereby lowering product costs and enhancing the competitiveness of similar products in the market.
Efficiency Improvement: Short charging time and significant temperature and humidity control effects make it highly suitable for long-term fresh storage, reducing loss, and ideal for storing high-value off-season products.

Feedback from Chongqing Liangping Prepared Food Industrial Park and Agricultural Service Group Customers:Compact, mobile, and convenient product for multiple scenarios: Available in 40-foot and 20-foot specifications, suitable for front-shop-back-warehouse use, convenient and quick, with no approval restrictions.

Energy-saving and low consumption, more economical with use: Phase-change cold storage containers save 80% energy compared to traditional refrigerated containers.

Excellent cooling and moisture retention, notably fresh: Phase-change cold storage technology maintains constant temperature and humidity, making it more suitable for preserving stem and leaf vegetables and fruits, extending freshness duration by 4 times compared to air-cooled environments.

Easy operation, reducing management costs: Fully digitalized operation with automatic startup and shutdown, intelligent management, visible temperature and humidity, and low-temperature alerts, reducing management costs across all scenarios.

Intelligent professional service, thoughtful and considerate:

Cold Chain Magic Cube provides comprehensive equipment operation management services, with a backend remote monitoring system, capable of addressing shortcomings in both ends of the cold chain logistics facilities. As a merchant, little operational and management effort is required, comprehensively resolving operational management pain points.

We are currently developing a more energy-efficient product integrated with solar power. The laboratory prototype has been completed, and it is being prepared for launch as our next-generation core product.
