Project Background
G.TECH Technology Việt Nam is a leading electronics and computer peripherals manufacturer in Vietnam, operating a large-scale production facility in a coastal industrial zone. The factory requires stable, continuous cooling for precision manufacturing processes, with strict requirements on water temperature stability and equipment uptime.
Cooling Challenges
The project faced three core challenges:
- High-humidity coastal environment: The factory is located near the coast, with high salt-spray concentration in the air. Conventional galvanized steel towers corrode rapidly, requiring replacement every 3–5 years.
- Continuous production requirements: Electronics manufacturing cannot tolerate unplanned downtime. The cooling system must maintain stable operation with minimal maintenance interruptions.
- Large cooling capacity: The production line requires 3200RT total cooling capacity, necessitating a parallel multi-unit configuration with balanced water distribution.
COOLTEK Solution
COOLTEK supplied 4 units of LH-800RT counterflow square cooling towers in parallel configuration:
- FRP shell construction: Full fiberglass-reinforced plastic (FRP) casing eliminates electrochemical corrosion paths, maintaining structural integrity in high-humidity, high-salinity coastal environments.
- Counterflow design: Air and water flow in opposite directions, maximizing heat exchange efficiency and achieving lower outlet water temperatures compared to crossflow designs of the same footprint.
- Parallel configuration: 4 units operating in parallel with balanced water distribution, allowing individual unit maintenance without shutting down the entire system.
- Extended maintenance cycle: FRP materials and optimized fill media extend the maintenance cycle to 18 months, compared to 6 months for conventional steel towers.
Project Results
After commissioning, the system achieved the following measurable results:
- Maintenance cycle extended to 18 months (vs. 6 months for conventional steel towers)
- O&M cost reduced by 60% compared to the previous steel tower system
- Zero unplanned downtime in the first 12 months of operation
- Outlet water temperature stability ±0.5°C meeting precision electronics manufacturing requirements
Frequently Asked Questions
Why choose LH counterflow towers for electronics manufacturing?
Electronics manufacturing requires strict outlet water temperature stability. The LH counterflow design achieves lower outlet temperatures with the same footprint compared to crossflow designs, and the FRP shell eliminates corrosion risks in coastal environments.
How does the parallel 4-unit configuration benefit maintenance?
With 4 units in parallel, individual units can be taken offline for maintenance without shutting down the entire cooling system, ensuring continuous production without interruption.
What is the expected lifespan of FRP cooling towers in coastal Vietnam?
FRP cooling towers in coastal Vietnam typically achieve 15–20 years of service life, compared to 3–5 years for galvanized steel towers in the same environment.
