Dedicated for 28 years, focused on one thing—San Nai Environmental Protection safeguards customer growth through practical actions.

In 1997, we started in Hangzhou and put down deep roots. Hydrometallurgical Electrolysis for Nonferrous Metallurgy The field—before we know it, twenty years have already passed. Eight several decades. Today, Hangzhou San Nai Environmental Protection Technology Co., Ltd. has grown from an initial single-equipment manufacturer into a company integrating R&D and... Design, Manufacturing, Install , a comprehensive service provider integrating services, and has also reaped... National-level Specialized, Sophisticated, and New "Little Giant" Enterprises and numerous other recognitions, including National High-Tech Enterprise and Zhejiang Province’s Hidden Champion Enterprise.

Since our establishment, we have been firmly committed to... “ Colored Electrolysis Process Technology and Equipment This race track. Now, The company’s main products and services include vinyl resin integral-cast electrolytic cells, complete sets of electrolysis systems, and integrated electrolysis equipment as supporting components. /Electrodeposition process services, etc. Our core products — “Vinyl Resin Integral-Cast Electrolytic Cell,” Right at birth It has filled a domestic gap and broken the international technology monopoly. Later again Passed The “Made in Zhejiang” standard has been widely adopted by major domestic smelting enterprises and listed companies.

Innovation is the core driving force behind our development, and technological R&D has never been just empty talk. Over the years, we’ve been genuinely committed to R&D and have undertaken national-level projects. The “New Nickel-Cobalt Electrolyzer and Acid Mist Control Technology” project under the 863 Program has won the First Prize of the China Nonferrous Metals Industry Science and Technology Award. Our “The application technology and equipment for electrolytic copper with a current density of 380 A/㎡” has been included in the National Catalog of Industrial Energy-Saving Technologies. ； "Three-Resistance Nickel Electrodeposition Process Technology" and equipment “經 Evaluation of Scientific and Technological Achievements by the China Nonferrous Metals Industry Association—Evaluation Result: Reach an internationally leading level 。 These technologies help customers reduce operating costs, improve production efficiency, and also enhance the production-line environment.

Our products and services have long since gone beyond national borders—from Kazakhstan and the United Kingdom to Saudi Arabia, Myanmar, and the Democratic Republic of the Congo—covering copper and zinc. 、 Nickel, manganese 、 Cobalt In the nonferrous metals sector and beyond, you can always spot our presence. Over the past few years, we’ve undergone a significant transformation. — From selling only equipment to being able to provide “process technology + solution design + manufacturing and installation.” A dragon's tail Service. In 2020, we launched the research and development and production of “intelligent electrolysis,” aiming to make our customers’ production smarter and greener.

“Sincerity and goodness, embracing virtue to go far” is our original aspiration that we steadfastly uphold. ， “Integrity, Innovation, Professionalism, and Collaboration” are our core values—and they also serve as the guiding principles for everything we do.
