1. Current Situation, Demand, and Challenges of the Cold Chain in Nghe An
Located in the tropical monsoon climate zone of North Central Vietnam, Nghe An is severely affected by the southwest monsoon (Lao air) in the summer, with outdoor temperatures frequently exceeding freezing. 39°C – 41°C, The humidity fluctuates extremely. These harsh weather conditions pose a huge challenge for processing and storage facilities:
- At VSIP, WHA, and Nam Cam industrial parks: Dozens of food processing plants, dairy factories, confectionery factories, and industrial kitchens serving hundreds of thousands of workers require cold storage (+2°C to +8°C) and freezer storage (-18°C to -22°C) that operate with absolute stability 24/7/365, without any temperature fluctuations that could damage raw materials.
- At the fishing ports of Cua Lo, Lach Con (Quynh Luu), and Lach Van (Dien Chau): The catch of mackerel, scad, cuttlefish, and shrimp reaches tens of thousands of tons each season. The lack of ultra-fast deep-freezing systems (-35°C to -40°C) causes seafood to suffer from cell damage (drip loss), reducing its export value.
- In the agricultural production areas of Quy Hop, Nghia Dan, and Ky Son districts: If Vinh oranges, passion fruit, and ginger are not placed in cold storage (pre-cooling) immediately after harvesting, they will lose moisture, their peels will wilt, and they will become infected with fungal diseases within just 3-5 days.

7. Frequently Asked Questions When Installing Cold Storage in Nghe An (FAQ)
1. Nghe An's summer climate is very hot and windy (Lao air). Will the cold storage facilities be overloaded?
Tan Long calculated the summer heat load coefficient at an outdoor ambient temperature of $T_a = 43^\circ\text{C}$ with a large heat exchange area air/water cooled condenser, combined with a high-density PIR panel to prevent overheating and compressor pressure drop.
2. In the coastal areas of Cua Lo and Quynh Luu, where there is salty air, how can we prevent rust on the cooling coils and warehouse casings?
For coastal seafood warehouses, Tan Long uses aluminum evaporator coils coated with epoxy to resist salt corrosion, or 304 stainless steel tube coils with specialized salt-resistant Colorbond sheet metal panels to protect the structure and ensure its durability for over 20 years.
3. Does Tan Long provide support for fire safety acceptance testing documents according to QCVN 06:2022/BXD at Nghe An Industrial Park?
Yes. The entire warehouse shell supplied by Tan Long uses PIR panels with fire-retardant certification from a specialized institute, and provides complete technical documentation for fire safety approval of industrial workshops in VSIP and WHA industrial parks.
