Vietnam Cold Storage Project – ZHX-2820 Evaporative Condenser
The unit arrived directly at the cold storage facility, as you can see from the project site photo.
This case demonstrates how modern evaporative condensers improve cold storage efficiency in Southeast Asia.
Project Background
Vietnam has been one of the fastest growing economies in Asia, with seafood, fruits and frozen products forming a major part of its export.
Cold storages are essential to guarantee product quality before shipping worldwide.
However, many traditional cooling systems in Vietnam consume too much electricity and water.
The client’s old unit was no longer reliable, and downtime directly meant financial loss.
Therefore, the decision was made to replace it with ZHX-2820 condenser.
About the ZHX-2820 Evaporative Condenser
The ZHX-2820 is designed for large cold storage applications and industrial refrigeration.
Some of its technical highlights include:
- Cooling capacity above 2800 kW, ideal for ammonia-based refrigeration.
- Heavy-duty axial fan system with optimized airflow distribution.
- Hot-dip galvanized steel and optional stainless-steel casing – ensuring long service life in humid climate.
- Energy saving compared with conventional shell & tube + cooling tower system.
- Modular structure for easier transportation and site assembly.
Installation at the Cold Storage Site
When the equipment reached the client’s site, the main task was to integrate it with the existing cold storage refrigeration system.
The site was located in a coastal area, so the design paid special attention to corrosion resistance.
The client also required minimal installation downtime because the cold room was storing seafood ready for export.
Within 72 hours, our engineers completed positioning, piping connection, and commissioning of the ZHX-2820 unit.
Challenges and Solutions
Several technical challenges appeared during the project:
- High humidity environment: Anti-corrosion coatings and drift eliminators were applied to avoid scaling.
- Limited space: ZHX-2820’s compact footprint allowed easy integration in a tight layout.
- Energy efficiency requirement: Fans and pumps were configured to meet local electricity tariff conditions.
- Water quality issue: A side-stream filtration and dosing system was installed to maintain water circulation quality.
Performance Results
After commissioning, the ZHX-2820 evaporative condenser has been running stably:
- Average condensing temperature reduced by 4–5°C compared with the old system.
- Energy consumption decreased by approx. 15%.
- Water saving due to optimized spray system and efficient drift eliminators.
- Noise emission controlled under local standard, suitable for urban area operation.
The client was very satisfied because the cold storage can now run longer hours with fewer breakdowns, directly improving their export supply chain reliability.
Why ZHX-2820 is Ideal for Cold Storage
For cold storage in Vietnam, equipment must face hot and humid summers, sudden load changes, and strict product preservation demands.
The ZHX-2820 was chosen because:
- High heat exchange efficiency – critical for frozen seafood and meat storage.
- Robust structure for tropical climate and salty air near the coast.
- Flexible installation, fits both new projects and replacement jobs.
- Lower total cost of ownership due to reduced operation and maintenance cost.
Impact on Vietnam’s Cold Chain Industry
Cold storage is a key factor in seafood processing, fruit preservation, and meat export.
With Vietnam exporting to markets like Japan, Europe, and the US, reliable refrigeration is not optional – it’s mandatory.
By upgrading to modern condensers, companies can improve competitiveness and sustainability.
What’s more, this project highlights the trend: many businesses in Vietnam are moving away from traditional cooling towers plus shell & tube condensers.
Instead, they choose closed-loop cooling systems and evaporative condensers that combine efficiency and compactness.
Conclusion
The Vietnam cold storage project using ZHX-2820 evaporative condenser proves how modern design can meet tough refrigeration demands.
From seafood exporters to fruit cold chains, adopting high-efficiency condensers means stable operation, lower cost, and environmental benefit.
