Jiangsu Zhaosheng Air Conditioning Co., Ltd., frequently recognized in international markets under the brand name Josun, is a specialized industrial manufacturer based in Taixing City, Jiangsu Province, China. Since its establishment in 1985, the company has evolved from a local machinery factory into a dedicated provider of environmental control systems tailored for the rigorous demands of the maritime, offshore, and defense sectors. Rather than focusing on general residential climate control, the enterprise concentrates its engineering resources on developing robust HVAC-R (Heating, Ventilation, Air Conditioning, and Refrigeration) solutions designed to withstand the corrosive, high-vibration, and variable-temperature conditions characteristic of marine environments.
The company’s operational scope encompasses the research, development, manufacturing, and service of complex climate control machinery. Its manufacturing facilities in the Taixing Economic Development Zone are equipped to produce a wide array of marine-grade equipment, ranging from centralized air conditioning plants and provision refrigeration units to ventilation fans and noise control devices. These systems are critical for ensuring crew comfort, protecting sensitive electronic equipment in machinery control rooms, and preserving cargo on board deep-sea vessels. The company maintains a strong focus on technical compliance, ensuring its products meet the stringent safety and quality standards set by major international classification societies, such as DNV, LR, ABS, BV, and CCS.
Over the decades, Jiangsu Zhaosheng has expanded its market reach beyond domestic shipbuilding. While it remains a significant supplier to the Chinese naval and commercial fleets, supplying equipment for naval vessels, research ships, and merchant carriers, it also exports to markets across Europe, Asia, and the Middle East. Its solutions are frequently integrated into diverse marine platforms, including offshore oil and gas rigs, engineering vessels, and wind power installation ships, where reliability is paramount.
In addition to hardware manufacturing, the company engages in system integration, offering engineering services that cover the entire lifecycle of marine climate control, from initial design consultation to installation and maintenance. By continuously adapting to the evolving regulations of the global shipping industry, such as energy efficiency requirements and environmentally friendly refrigerant mandates, Jiangsu Zhaosheng Air Conditioning Co., Ltd. serves as a comprehensive partner for shipyards and shipowners requiring specialized marine thermal management systems.
