This May, Suzhou Xiechang Environmental Protection Technology Co., Ltd. (Xiechang) achieved a new milestone by being named a “Top-Tier Enterprise” (Jianfeng Enterprise) among key manufacturing firms in the Suzhou Industrial Park. For over 30 years, Xiechang has maintained its industry leadership through relentless transformation and strategic upgrading.
Deep Cultivation in Niche Markets
Since its inception, Xiechang has specialized in the R&D and manufacturing of core components for baghouse dust collectors and their intelligent control systems. The company has secured multiple certifications, including ISO9001, ISO14001, OHSAS18001, and the Integration of Information and Industrialization. All products are certified for environmental protection, with flagship lines obtaining CE and Explosion-Proof (Ex) certifications.
The “Xiechang” brand is synonymous with high performance, premium service, and cost-effectiveness, serving vital industries such as Power Generation, Metallurgy, Construction Materials, Waste Incineration, and Chemical Engineering. Industry statistics reveal that since 2017, Xiechang’s Pulse Jet Valves have commanded a domestic market share of over 25%.
“Import Substitution” and R&D Breakthroughs
From the outset, Xiechang targeted “Import Substitution” as its strategic goal. By investing in a specialized dust collection laboratory, the company broke through critical technical bottlenecks, transitioning from a traditional manufacturer to a high-tech enterprise driven by digitalization and intelligence.
Key data highlights this evolution:
-
Innovation Milestones: In 2011, the DMY series ultra-low pressure pulse jet valve was recognized as a National Key New Product. In 2013, Xiechang was designated as the Jiangsu Provincial Bag Dust Collection System Engineering Technology Research Center.
-
Revenue Optimization: In 2007, sales of self-developed pulse jet valves accounted for less than 30% of total revenue. By 2019, this figure soared to 68.41%, completing a total optimization of the product structure.
Defending the Quality of “Made in China”
In a market often plagued by price wars and compromised quality, Xiechang pivoted toward the mid-to-high-end segment. “We would rather lose some market share than compromise on the reputation of Chinese brands,” stated General Manager Ms. Liu Jin.
She spearheaded a specialized Customer Service Department with a bold commitment: “48-hour response within the Yangtze River Delta and 72-hour response nationwide.” For major terminal clients, Xiechang provides dedicated on-site technical guidance to help users optimize dust control efficiency and reduce operational costs. “While purchase frequency may seem to decrease, our client and product structures are achieving a deeper, more refined integration,” Chairman Mr. Liu Weidong remarked in a CCTV interview.
The Third Transformation: IoT and Smart O&M
Xiechang is now executing its third major transformation: evolving from a component supplier to an Integrated Solution and O&M (Operation & Maintenance) Service Provider.
Building on its e-commerce foundation established in 2012, Xiechang integrated IoT (Internet of Things) with baghouse technology in 2016. This led to the development of a Cloud Management Platform for dust collection and the industry-leading Smart Pulse Jet Valve.
This holistic solution enables real-time remote monitoring of dust collection systems. Its “Mobile Inspection” feature solves the traditional “Expensive, Dangerous, and Slow” issues of manual inspections, opening a new chapter in Intelligent O&M and driving the digitalization of the entire industrial air filtration industry.
