Explore our top-tier stainless steel panel reservoirs, heat dissipation towers, and high-performance commercial ventilation units designed for heavy industrial and municipal installations.
Modern civil architecture and industrial fluid containment have shifted decisively from non-sustainable concrete basins to modular stainless steel panel (sectional) water tanks. Discover the microstructural and economic factors driving this transition.
Unlike concrete reservoirs that crack, foster microbial biofilm, and leach alkali compounds, deep-stamped SUS304/SUS316 panel water tanks feature totally non-porous surfaces. They resist algae growth and ensure clean storage compliant with global drinking water directives.
Fabricated using standard 1000×1000mm, 1000×500mm, and 500×500mm hydraulic stamped plates, these units solve tight indoor retrofit challenges. Components pass through regular doorways and freight elevators, ready for on-site TIG argon welding.
Engineered with spherical arc stamping geometry, the panels evenly distribute hydrostatic pressure across all wall joints. Reinforced with internal SUS tie-rods and cross-bracing, our tanks withstand severe ground vibration and thermal contraction stresses.
International EPC contractors face distinct operational demands. Choosing the appropriate alloy grade and tank construction prevents premature crevice corrosion and structural fatigue over decades of use.

We supply turnkey equipment packages combining stainless modular reservoirs, closed evaporative towers, and fire exhaust fans across critical global commercial and industrial sectors.
Installed across large-scale municipal EPC operations like the Thailand Urban Water Supply and Sewage Treatment Project, our high-volume SUS316 tanks and counterflow towers handle high throughput with zero trace chemical contamination.
Heavy plants demand closed-circuit cooling loops to isolate treated process water from air dust. Coupled with welded stainless reservoirs, our systems protect smelting furnaces and cracking units across Vietnam and Indonesia from catastrophic overheating.
Microchip foundries and hyper-scale server clusters require steady chill lines and high-temperature smoke venting. Our ultra-quiet mixed-flow fans, fire dampers, and sanitary tanks provide coordinated, fail-safe climate and safety operations.
Modern high-rises and underground transport hubs use buried fire tanks to maximize above-ground real estate. In emergencies, high-temperature axial smoke-exhaust systems clear escape routes while high-pressure reserve tanks feed sprinklers.
Every component leaves our 12,000 m² Dezhou production base with traceable mill test reports, third-party inspection dossiers, and certified structural verifications.
We work directly with SGS, Bureau Veritas (BV), and TÜV to provide non-destructive testing (NDT), weld seam radiographic examination, dye penetrant tests, and pressure-holding verifications before container loading.
All fan motors, cooling pump assemblies, and digital control sensors are configured to local job site electrical requirements: 220V/380V/415V/460V at both 50Hz and 60Hz. Standard equipment comes with IP55/IE3 high-efficiency ratings.
Components ship from nearby Qingdao and Tianjin ports with anti-scratch PE film and fumigated wooden pallets. Steel framing safeguards panel corners, and moisture-absorbing desiccant packs prevent transit oxidation.
Driven by smart HVAC requirements, building decarbonization, and BIM integration, our Dezhou engineering teams continue to upgrade containment resilience and thermal fluid dynamics.
Introducing lightweight, duplex stainless steels (such as 2205) into standard modular stamping to yield 2x the tensile yield strength of 304 while resisting stress corrosion cracking in high-chloride conditions.
Replacing manual TIG welding with fully automated fiber laser setups. This slashes heat-affected zones (HAZ) by 70%, preventing carbide precipitation and ensuring exceptional long-term seam strength.
Embedding IoT hydrostatic pressure sensors, digital water temperature probes, and capacitive leak cords directly into the lower support channel beams to feed building management systems (BMS).
Upgrading cooling tower drift eliminators and variable frequency drive (VFD) mixed-flow fans to cut water drift below 0.001% of total circulation and lower operating noise for dense urban installations.
Clear answers to technical, commercial, and structural inquiries to streamline spec approvals for procurement teams and consulting engineers.
Shandong Fengdun Environmental Technology Co., Ltd. is an original equipment manufacturer (OEM/ODM). All cooling towers, axial and mixed flow fans, fire smoke dampers, and stainless panel tanks are fabricated directly in our 12,000 m² factory in Dezhou, Shandong. Overseas buyers purchase factory-direct with clear pricing and direct engineer access.
SUS304 provides an economical, sanitary solution for domestic potable water, general building fire reserves, and closed HVAC loops where chloride stays below 200 ppm. SUS316 adds 2-3% molybdenum to counter chloride pitting and crevice corrosion, making it essential within 5 km of coastlines or near chemical processing lines.
Yes. Our engineering division creates tailored structural layouts matching plant-room constraints, including L-shaped configurations and low-overhead designs. Inlet, overflow, drain, and supply flanges (DN25 to DN500) can be configured to ANSI, DIN, or JIS standards along with ladder access, sight level gauges, and partition walls.
Open cooling towers offer a lower upfront purchase cost for general comfort chillers. However, closed circuit cooling towers isolate fluid inside internal copper or stainless coils, keeping dirty ambient air out. This prevents scaling and fouling in sensitive equipment like high-frequency induction furnaces, cleanroom process lines, and data centers.
Quality begins with high-precision hydraulic molds that form clean flanges. During assembly, certified welders use argon TIG processes with matched-alloy wire. Once finished, tanks undergo a 24- to 48-hour hydrostatic head test along with dye penetrant checks along critical corners to ensure 100% leak-proof delivery.
