Fujian Longking Co., Ltd.

Fujian Longking Co., Ltd. is China's premier industrial air pollution control equipment manufacturer and the world's largest producer of electrostatic precipitators, headquartered in Longyan, Fujian Province. Founded in 1971, Longking has accumulated over five decades of specialized expertise in particulate matter and gaseous pollutant control, amassing a cumulative installed base of more than 1,000GW of ESP capacity worldwide. The company generated approximately RMB 12 billion in revenue in 2025, secured RMB 10.26 billion in new orders, and employs over 7,000 people. Backed by Zijin Mining Group, Longking has recently diversified into lithium iron phosphate battery manufacturing, achieving profitability in this new venture and positioning itself at the intersection of pollution control and clean energy.

Core Business

Longking's business is anchored by its world-leading air pollution control equipment franchise, organized across three primary technology platforms. The electrostatic precipitator division is the company's foundational business and remains its competitive crown jewel, with over 1,000GW of cumulative installed capacity serving coal-fired power plants, steel mills, cement kilns, and non-ferrous metal smelters across China and international markets. Longking supplies complete ESP systems including collecting plates, discharge electrodes, high-voltage power supplies, and rapping mechanisms—all manufactured in-house at the company's massive Longyan production complex. The flue gas treatment division provides wet and dry flue gas desulfurization systems, selective catalytic reduction denitrification units, and integrated multi-pollutant control solutions that enable industrial clients to meet increasingly stringent ultra-low emission standards. Longking's catalyst manufacturing capability for SCR systems is a key differentiator, providing vertical integration that reduces costs and ensures quality control. The company's newest and most strategically significant division is its LFP battery manufacturing business, which has ramped an 8GWh annual production capacity to profitability. This venture leverages Longking's decades of industrial process engineering experience and benefits from Zijin Mining's lithium supply chain to produce battery cells and energy storage systems for grid-scale and commercial applications—representing a potential multi-billion dollar second growth engine.

Key Strengths

Longking's competitive position is supported by five powerful pillars. First, as the world's largest ESP manufacturer with over 1,000GW of installed capacity, Longking possesses an unparalleled reference list, engineering database, and operational track record that creates enormous barriers to entry for potential competitors. Second, the RMB 10.26 billion in new orders secured in 2025 represents a 34% year-over-year increase, demonstrating accelerating demand momentum and strong market confidence in Longking's technology platform. Third, the backing of Zijin Mining Group provides strategic advantages including access to competitively priced raw materials, financial firepower for large-scale projects, and the credibility of a Fortune Global 500 parent company. Fourth, Longking's diversification into LFP battery manufacturing has achieved profitability at an early stage, validating the company's strategic pivot and creating an option on the rapidly growing energy storage market. Fifth, tightening global emissions standards for coal-fired power and heavy industry in developing nations create a massive addressable market for Longking's established and proven pollution control technologies.

Challenges & Outlook

Longking faces a complex outlook defined by both extraordinary opportunities and significant transition risks. The company's core ESP and flue gas treatment business benefits from China's continued enforcement of ultra-low emission standards and the global trend toward tighter industrial air quality regulations, particularly in Southeast Asia, South Asia, and Africa where coal-fired power capacity continues to expand. International markets represent a substantial growth opportunity as Longking leverages its cost competitiveness and 1,000GW reference base to win overseas contracts. The LFP battery manufacturing division is a strategic bet that could transform Longking's growth trajectory if the company can establish a meaningful position in the competitive energy storage market, with Zijin Mining's lithium resources providing a critical cost advantage. However, the company faces meaningful headwinds including the long-term secular decline of coal-fired power generation in developed markets, which could eventually limit ESP demand growth. The LFP battery venture operates in an intensely competitive industry characterized by rapid technological change, significant manufacturing overcapacity, and aggressive price competition from established battery manufacturers including CATL and BYD. Longking's ability to differentiate its battery products, achieve manufacturing scale, and maintain profitability in this challenging environment will be decisive. The company's dual identity as both a pollution control leader and an emerging clean energy manufacturer creates a complex narrative that may not be fully appreciated by public market investors.
