In the scorching summer, the growing demand for “fresh ingredients and food delivered straight to your door” continues to drive rapid development of the food cold chain industry. To ensure the freshness and safety of these goods, a low-temperature environment is essential — many ingredients and food products must be stored and transported at temperatures below -18°C. Against this backdrop, automation in low-temperature warehouse handling has become an inevitable trend in the industry, and the performance of conveying equipment directly determines the stability and operational efficiency in such cold environments.

Traditional electrical rollers typically use an inner-rotor motor combined with a planetary gear reducer. However, due to limitations in the planetary gear lubrication system, their operating temperature range is usually restricted to between +40°C and -5°C. To meet the requirements of environments below -18°C, more expensive, specialized low-temperature refrigeration-type electric rollers must be used. This not only increases the complexity and cost of technical selection and manufacturing for equipment manufacturers but also places greater pressure on end-users in terms of spare parts maintenance and long-term costs, becoming a major pain point in the development of cold chain automation.

To address this industry challenge, Damon Industry has introduced an innovative solution: the direct drive servo electric roller. Its core advantage lies in a breakthrough over traditional structures—by eliminating the planetary gearbox, it completely removes the temperature limitations of lubrication systems.

This design allows the standard universal model of the direct drive servo electric roller to operate reliably in environments as cold as -20°C, without the need for special low-temperature versions. It simplifies the selection process, avoids additional costs, and meets the stringent requirements of low-temperature transportation for food and pharmaceutical products perfectly.

At the same time, the Damon Industry direct drive servo electric roller is equipped with advanced servo control technology, achieving a precise balance between output speed and torque. With just three main product categories, it can cover the full range of customer application needs—whereas traditional electric rollers often require over ten different models to achieve the same coverage.

This streamlined approach not only simplifies product selection for customers and reduces the variety of roller models needed in a project, but also eases the burden of spare parts inventory for maintenance. Additionally, it gives conveyor systems greater flexibility and a broader range of applications, helping customers adapt to complex and ever-changing business environments at a lower cost.

Thanks to its outstanding performance in low-temperature environments, the Damon Industry direct drive servo electric roller has been highly favored by the market since 2023. It has been widely adopted and is operating reliably in leading domestic food and pharmaceutical cold chain distribution companies, establishing a solid technological foundation for ensuring food freshness and pharmaceutical safety.

By 2025, this innovative product will have expanded beyond China’s borders, delivering reliable service and value to international clients in low-temperature automation. It continues to drive the global advancement of automated cold chain logistics for food and pharmaceuticals.
