SummaryShanghai Dasen Industry Co., Ltd. is a China-based limited company established in 2011 and located in Fengxian District, Shanghai. It operates in refrigeration and cooling solutions, offering chillers, cooling towers, pumps, cold rooms, and refrigeration spare parts. The supplier reports four production lines, 47 employees, and export sales representing 51%–70% of total sales. Its stated capabilities include customized application programs, professional engineering support, installation experience, Internet-based service, and an internally developed customer APP covering pre-sale, sale, and after-sale stages. The available information does not confirm certifications, customer cases, or sufficient evidence for financial credibility. Quality-control staffing is reported as fewer than five people, which indicates a relatively small dedicated quality-control team.

Supplier typeThe supplier is identified as a trade company and a limited company, established in 2011 in Shanghai, China. Its business model combines refrigeration manufacturing-related resources with professional cold-storage services and offers a defined range of industrial cooling products.

After-Sales capabilityThe supplier states that its APP supports customers from pre-sale through after-sale and describes an Internet-based service concept, experienced installation personnel, and professional service for industrial refrigeration, cold storage, and fruit-ripening systems. These statements provide explicit evidence of planned after-sales and installation support.

R&D capabilityThe supplier reports integration of domestic high-tech manufacturing, foreign patented technology, an Internet-based service concept, and a newly developed customer APP. These stated technology and service-development activities support a positive assessment of innovation capability.

Production capacityThe supplier reports four production lines and offers multiple chiller, cooling tower, pump, cold-room, and spare-parts products. However, the available information does not quantify capacity by product or provide detailed manufacturing facilities, so the evidence supports established production capability but not a comprehensive capacity assessment.

Customization capabilityThe company explicitly states that professional engineers develop customized application programs to meet different customer demands. Its stated experience spans industrial, commercial, and cold-storage fields, supporting a clear customization capability.
