About Hanyork
Development History of Changzhou Baoshan Group – Dedicated to Cold Chain Technology, Leading the New Era of Energy-Saving InsulationSince its establishment in 1997, Changzhou Baoshan Group has been committed to providing energy-efficient cold chain solutions for global clients. With four core subsidiaries—Changzhou Baoshan Refrigeration Equipment Co., Ltd., Changzhou Caineng Refrigeration Technology Co., Ltd., Jiangsu Keleng Energy-Saving Technology Co., Ltd., and Changzhou Hanyork Refrigeration Equipment Co., Ltd.—the group has built a comprehensive industry chain covering cold storage insulation materials, R&D and manufacturing of refrigeration equipment, and globalized services, solidifying its position as a technological leader in the cold chain industry.
The Foundation: Pioneering Cold Storage Insulation (1997-2018)
In 1997, Changzhou Baoshan Refrigeration Equipment Co., Ltd. was founded, specializing in the research, development, and production of polyurethane cold storage panels (PU panels) and cold storage doors. Renowned for their superior thermal insulation and durability, these products quickly became the preferred choice for food freezing, pharmaceutical storage, and other industries, establishing the group’s dominance in the cold storage insulation materials market.
Innovation & Expansion: Building Integrated Cold Chain Solutions (2019-2020)
In 2019, the group established Changzhou Caineng Refrigeration Technology Co., Ltd., expanding into the independent R&D and manufacturing of core equipment such as refrigeration units and cold air blowers. By integrating energy-efficient technologies, these products became widely adopted in cold chain logistics, industrial refrigeration, and other sectors, offering clients one-stop solutions from insulation to refrigeration.
In 2020, to meet growing global demand, the group invested in a 167-are smart manufacturing base and founded Jiangsu Keleng Energy-Saving Technology Co., Ltd. This subsidiary focuses on producing high-performance composite insulation materials, including PU insulation panels and PR insulation panels, further strengthening the group’s competitive edge in energy-efficient construction and cold chain storage.
Global Reach: Embarking on Internationalization (2021-Present)
In 2021, Changzhou Hanyue Refrigeration Equipment Co., Ltd. was launched, marking the group’s strategic shift toward global markets. Leveraging its self-developed refrigeration units, cold air blowers, and full-range insulation panels, the group’s products are now exported to Southeast Asia, Europe, Africa, and beyond, delivering efficient and eco-friendly cold chain equipment and technical support to clients worldwide.
