About Us

These products primarily serve six key sectors: pharmaceutical chemicals, fine chemicals, pesticide intermediate production, new materials manufacturing, laboratory R&D, and exhaust gas treatment in coating operations. In the pharmaceutical and chemical industries, stainless steel reactors and heat exchangers are utilized for active pharmaceutical ingredient (API) synthesis, extraction, and crystallization; PPH corrosion-resistant storage tanks and conductive filament-wound equipment are suited for the storage and transfer of corrosive organic solvents; and exhaust purification towers and swirl-plate towers handle the treatment of acidic/alkaline and VOC-laden exhaust gases from chemical workshops. Explosion-venting tanks provide safety pressure-relief protection for flammable and explosive reaction processes. Laboratory equipment supports small-scale and pilot-scale R&D at universities and pharmaceutical companies; vacuum processing systems are widely used for the negative-pressure concentration and drying of chemical materials; and precision filters and foot-operated filters are employed for the purification of pharmaceutical solutions and the filtration of chemical process fluids. The equipment is adaptable to small-to-medium production workshops and centralized exhaust treatment projects in industrial parks, catering to needs ranging from standalone units for small laboratories to complete environmental protection production lines for ten-thousand-ton-scale chemical plants.

The company's qualifications fall into three main categories: specialized environmental protection qualifications, pressure vessel qualifications, and proprietary patents; it holds more than six granted patents. Its environmental qualifications include the Zhejiang Environmental Protection General Contracting Certificate (No. J-026) and the Zhejiang Environmental Protection Specialized Design Certificate (No. J-037), authorizing it to undertake specialized design and general contracting construction for environmental engineering and waste gas treatment projects within Zhejiang Province. It also holds a pressure vessel qualification (Certificate No. 4084321) for the manufacture of Class I and Class II pressure vessel equipment, and its anti-static PPH wound air ducts are backed by authoritative third-party test reports. Regarding patents, the company obtained utility model patents for an explosion-venting tank (ZL201820974930.0) and an environmental vacuum treatment system in 2018. In 2021, it was granted a patent for a waste gas swirl-plate tower (ZL202022635678.0). Additionally, it holds multiple utility model patents-covering items such as vertical waste gas purification towers, flap-type one-way valves, and roller molds for wall pipes-as well as one invention patent. The company is the sole patentee for all these patents, with Ren Shanchao serving as the primary inventor; all patents are subject to the statutory 10-year validity period.

The company has fully equipped itself with machinery for stainless steel processing, plastic winding, and precision testing, establishing a comprehensive, in-house production system. The stainless steel workshop features CNC shearing machines, bending machines, plasma cutters, vertical boring machines, and automatic argon arc welding equipment, utilized for the forming and welding of reactor vessels, heat exchangers, and sheet-metal air ducts. The plastic workshop is outfitted with fully automatic PE/PPH winding units, plastic extruders, and hot-air welding equipment, enabling the integrated winding and forming of anti-corrosion tanks and anti-static air ducts. The precision testing area is equipped with hydrostatic pressure testers, airtightness detectors, static resistance testers, and corrosion simulation testers to conduct comprehensive testing on pressure vessel integrity, anti-static performance, and corrosion/weather resistance. Multiple overhead cranes and forklifts are available for handling large finished products, while in-house mold processing capabilities allow for the independent production of non-standard tooling-such as winding mandrels-thereby reducing reliance on external contractors and ensuring both delivery schedules and machining precision.

Centering its domestic operations on Zhejiang Province, the company has deeply cultivated the local pharmaceutical and chemical industrial parks in Jiaojiang, Linhai, and Huangyan (Taizhou). Its business extends to pharmaceutical and chemical enterprises across Zhejiang while simultaneously expanding into waste gas treatment projects in major chemical-producing provinces such as Jiangsu, Shandong, Anhui, and Jiangxi. Leveraging its environmental protection qualifications in Zhejiang, the company consistently undertakes turnkey projects for centralized waste gas treatment in provincial industrial parks, having served hundreds of pharmaceutical and fine chemical enterprises to date. Backed by a manufacturing reputation built over three decades, its custom-engineered equipment is sold to chemical industry clusters in South and Southwest China, while its standardized corrosion-resistant PP storage tanks and filters are integrated into supply chains for export-oriented chemical equipment. Specializing in this niche sector, the company ranks among the leading local manufacturers of waste gas purification equipment for the pharmaceutical and chemical industries. It has secured numerous orders for RTO-integrated pre-treatment equipment in industrial parks based on its patented products and has leveraged its proximity to undertake extensive on-site installation projects within Taizhou; the company maintains a consistently high project completion rate, with repeat business from existing clients exceeding 60%.
