Direct OEM/ODM Power Infrastructure for Hai Phong's Manufacturing Renaissance
Hai Phong has rapidly transformed into Northern Vietnam's core maritime and high-technology manufacturing epicentre. With key industrial zones including DEEP C Industrial Zones (Dinh Vu - Cat Hai), VSIP Hai Phong, Trang Due Industrial Park (anchored by global leaders like LG Electronics and its ecosystem), and Nam Cau Kien, plant managers face rigorous technical demands for electrical reliability, thermal stability, and operational efficiency.
Operating industrial equipment in Hai Phong presents a distinct environmental hurdle: coastal humidity frequently exceeding 85%, corrosive airborne sea salts carried by winds off the Gulf of Tonkin, and periodic factory voltage sags during peak seasonal demand. Under these rigorous manufacturing conditions, standard commercial off-the-shelf power packs inevitably experience dielectric breakdown, electrolytic degradation, and catastrophic thermal throttling. Guangdong Fenvix Technology Co., Ltd. bridges the critical gap between world-class power engineering and Hai Phong's rapidly expanding operational lines.
Headquartered in Guangzhou, Guangdong, Fenvix sits at the heart of the Greater Bay Area's high-power electronics corridor. We engineer and build custom constant voltage power supply cabinets, high-frequency switch-mode rectifiers (SMPS), and high-capacity static frequency converters capable of sustaining seamless duty cycles across automotive assembly plants, automated surface treatment facilities, semiconductor assembly shops, and commercial shipyards.
Localized Applications Across Hai Phong Industrial Parks
Designed around the exact operational profiles of industrial park tenants in Dinh Vu, Trang Due, VSIP, and An Duong.
Automotive & E-Mobility Manufacturing
Within Hai Phong's expanding automotive industrial clusters, such as the major manufacturing lines at Dinh Vu - Cat Hai, our constant voltage and constant current rectifiers power electrophoretic coating (E-coat) processes. Delivering stable voltage outputs from 100V up to 800V with under 1% RMS ripple factor, Fenvix rectifiers eliminate paint film defects, ensuring precise anodic and cathodic deposition thickness on chassis components and electric vehicle structural bodies.
Precision Electronics, Displays & PCBs
Trang Due and VSIP Hai Phong host premier tier-one suppliers manufacturing smart displays, mobile parts, and microelectronics. Our high-frequency IGBT DC rectifiers provide stable 6V, 12V, and 15V outputs up to 6000A for continuous reel-to-reel and PCB gold, silver, copper, and tin plating. Extremely fast dynamic response times prevent micro-overvoltages that would otherwise damage delicate semiconductor interconnects.
Shipyard Fabrication & Marine Operations
As Vietnam's premier maritime gate, Hai Phong's extensive marine repair yards (such as Bach Dang Shipyard and Song Cam) demand extreme-current surface conversion equipment. Fenvix supplies water-cooled and high-ingress air-cooled DC electrolysis supplies, zinc sacrificial anode activation units, and heavy-duty 400Hz shore-to-ship static frequency converters (up to 930kVA) tailored for marine electrical bus testing and dockside commissioning.
Green Metallurgy & Wastewater Treatment
Ecological zones like Nam Cau Kien enforce tight industrial effluent standards. Our programmable auto-polarity reversing DC power supplies (e.g., 48V 625A 30kW) are built specifically for electrocoagulation, electrochemical advanced oxidation processes (EAOP), and automated descaling. Cyclic polarity switching cleans sacrificial electrodes automatically, eliminating manual plant downtime and saving on labor.
Architectural & Aerospace Anodizing
High-end aluminum structural extrusion lines across An Duong rely on our programmable anodic oxidation rectifiers. Multi-stage constant-current and constant-voltage step ramps prevent thermal shock cracking on structural profiles, yielding uniform oxide layer thickness, optimal dielectric strength, and deep color absorption for architectural hardware and aerospace fixtures.
Cat Bi International Airport Support (GSE)
Cat Bi Airport (HPH) plays a pivotal role in cargo logistics connecting northern Vietnam to regional manufacturing hubs. Fenvix engineers deploy solid-state 28.5V DC Ground Power Units (GPUs) with peak starting currents up to 2000A, alongside 115V 400Hz frequency converters, replacing noisy diesel generators for hangar avionics testing and turn-around line maintenance.

Why Sourcing Directly from Fenvix Outperforms Local Trading Intermediaries
Combining the agile manufacturing ecosystem of Guangdong with direct logistics into Hai Phong Port.
In-House Precision Fabrication
Unlike trading agents who re-box mass-market units, Fenvix controls every mechanical and electrical step. Our Guangzhou workshop features CNC shearing machines, high-tonnage punching presses, milling stations, and copper busbar routing benches. We design transformer cores, wind inductors, and optimize thermal heatsink placement internally for guaranteed performance under continuous industrial loads.
Zero Minimum Order Quantity (No MOQ)
We respect the iterative nature of modern industrial tooling and pilot qualification runs. Hai Phong R&D engineering teams can purchase a single customized prototype unit for an initial automated bench test or production trial. Once verified, our scalable ISO 9001 assembly lines can deliver full container-load production rollouts seamlessly.
Audited ISO 9001 & TÜV Rheinland Verified
Quality assurance is backed by hard documentation. Guangdong Fenvix operates under audited ISO 9001 management protocols. Our production methodologies, testing benches, and export operations are verified on-site by TÜV Rheinland. Specific series carry rigorous European CE, Low Voltage Directive (LVD 2014/35/EU), and Electromagnetic Compatibility (EMC 2014/30/EU) compliance certs.
Full Burn-In & Load Verification
No power cabinet leaves our facility without extensive 100% full-load burn-in cycles. Utilizing calibrated digital oscilloscopes, temperature-sensing thermal cameras, and electronic dummy loads, we document output voltage ripple, harmonic distortion, transient load response, and cooling dissipation under real-world ambient benchmarks.
Direct Sea & Land Freight Logistics
Situated in Guangzhou, Fenvix leverages lightning-fast maritime and cross-border transport channels to Hai Phong. Shipments dispatched via Guangzhou/Shenzhen ports arrive at Hai Phong Port (Tan Vu, Dinh Vu, Lach Huyen) in as fast as 3 to 5 days, while express overland freight via the Pingxiang/Lang Son border corridor ensures urgent replacement components or pilot power supplies reach your dock in record time.
Comprehensive Multilingual Technical Support
We eliminate language friction in industrial supply chains. Our experienced electrical engineering department directly handles technical communication in English, ensuring detailed schematic confirmations, remote commissioning support via high-definition video calls, and comprehensive Vietnamese language wiring guidelines for local plant maintenance operators.
