About Us

Jiangsu Renhe Energy Saving Technology Co., Ltd. is part of the Jiangsu Renhe Group. Its parent company, Jiangsu Renhe Environmental Protection Equipment Co., Ltd., was established in 2004 and is headquartered in the Beiguo Industrial Park, Jiangyin City, Jiangsu Province. From its inception, the company focused on the air filtration sector. Between 2004 and 2008, it launched its first filter cartridge production line, expanded into industries such as shipbuilding, container manufacturing, and petrochemicals, and pioneered the domestic introduction of U.S.-made HV nanomaterials to optimize filtration performance.

Over nearly two decades of development, the company has steadily expanded its business footprint. From 2009 to 2011, it launched production lines for dust collectors and air intake filters and established long-term partnerships with five major industrial gas companies. Between 2012 and 2015, it successfully optimized large-scale gas turbine intake filtration systems, entered sectors such as automotive, chemical processing, and home appliances, and established the Wuxi High-Efficiency Energy-Saving Dust Removal and Filtration Engineering Technology Center. From 2016 to 2019, the company tackled the challenges of managing toxic, hazardous, flammable, and explosive dust, entered the semiconductor and new energy industries, and established long-term supply partnerships with five of the world's leading compressor brands.

From 2020 to 2023, the company strengthened collaborations with a German doctoral team and the China University of Mining and Technology to develop core materials, while expanding into sectors such as additive manufacturing, food processing, grain handling, pharmaceuticals, and underground mining. To meet growth needs, the company acquired 30 mu of land in the Zhangjiagang High-Speed ​​Railway New City to build a green, intelligent manufacturing plant and initiated the establishment of the Renhe Research Institute to further bolster its R&D capabilities.

Equipped with eight production lines utilizing advanced processes-such as precision media pleating and end-cap sealing-the company achieves an annual output of 250,000 filter cartridges.

Advanced processes-including laser cutting, CNC bending, and fixture-based assembly-are employed to ensure high machining precision and assembly quality.

The company maintains a quality inspection department equipped with a wide range of testing instruments; it manages an equipment inventory and annual inspection schedule, conducting rigorous spot checks on on-site materials and purchased raw materials. Dedicated testing roles are also established to oversee product experimentation and performance testing.

The Zhangjiagang Energy-Saving and Environmental Protection Headquarters Base project, currently under construction, will feature production lines for energy-saving equipment and new materials. By introducing state-of-the-art manufacturing equipment, the company aims to further enhance its production capacity and manufacturing capabilities.
