Chengrong Ultrafiltration Factory: Not Just Ordinary
Chengrong Factory has been focusing on stainless steel ultrafiltration (UF) water filters and purifiers for 18 years, with only one core product for the whole factory
In 2025, we launched our own brand—ChengrongEra (诚荣时代®), a high-end ultrafiltration water purifier brand benchmarked by global peers
Shenzhen Chengrong Factory：
-- Top 3 factory in the stainless steel pipeline ultrafiltration (UF) water filters and purifiers sector
-- The only full-chain ulfiltration manufacturer of its kind in the industry
-- Trusted ODM/OEM partner to multiple world-leading water purifiers brands
Chengrong Factory was established on May 6, 2008. It’s one of the last few factories that cover the whole supply chain for ultrafiltration membranes and UF water purifiers. Basically, it’s the benchmark all global peers in the UF industry look up to.
We put R&D first, update products nonstop, and always have customers' backs. Out of nearly 4,000 industry peers in China, fewer than 10 have got the "National High-Tech Enterprise" title, but Chengrong factory is one of them.
Four unique product lines:
1. Under-sink Mineral-Retaining UF Water Purifier for Drinking: Could retain natural minerals and trace elements in drinking water, which is an advantage that RO water purifiers cannot achieve
2. Whole-House UF Water Filtraton System: Installed on the main water inlet pipeline, it can effectively intercept sediment, rust, and other particulate impurities, filtering tap water, turbid well water and muddy water to crystal clarity, providing clean water for the entire home.
3. Commercial Mineral-Retaining UF Water Purification Machine: Provide clean and healthy drinking water for schools, offices, hotels and other commercial places, while retaining natural minerals and trace elements in the water, which is an advantage that RO water purifiers cannot achieve.
4. Complete set of water purification equipment for water treatment plants: With customization options to produce mineral-retaining water, purified water, and ultrapure water, tailored to meet specific client requirements.
We conduct 3 to 4 technical upgrades annually, ensuring Chengrong's Ultrafiltration membrane technology and quality far ahead of our peers.
Over the past nearly 20 years, Mr. Zhuang Beikan (庄贝刊) has run the factory with the core value of "Integrity as Pride." His goal is to ensure the factory's customers sleep soundly, making our customers increase their market profits by 10%, truly turning the concept of "zero customer worries" into reality.
From its early days, when Chengrong Factory focused on manufacturing hardware parts, processing stainless steel casings for UF water filters and purifiers, and providing ODM/OEM services for complete UF water purifiers, all staff have adhered to the ISO 9001 international quality certification system, with an annual investment of over 360K RMB into quality checks.
Later, the factory established its own ultrafiltration membrane production facility, and further expanded into the engineering sector, covering commercial water supply equipment and equipment for urban water treatment plants.
Starting as a small workshop with only 10 employees, it has grown into a full-supply-chain factory with 280 staff, a feat rarely matched by any other factory in the industry.
In 2025, Chengrong Ultrafiltration Factory launched its own brand--Chengrong Era (诚荣时代®), targeting the top 2% high-end market. In terms of quality and functionality, it has already become a benchmark that ultrafiltration industry peers worldwide are looking to match.
