Dong Thap is known as the catfish and mango capital of the Mekong Delta region, with a commercial catfish production exceeding 500,000 tons per year, concentrated in... Sa Dec, Thanh Binh, Hong Ngu, Cao Lan, along with the famous Cat Chu and Cat Hoa Loc mango orchards in Cao Lanh, Lap Vo and processed products from Thap Muoi lotus. To meet the stringent export standards for pangasius fillet to the US (USDA) and Europe (BRC), and to keep mangoes fresh for the Japanese and Korean markets, investing in an internationally standardized industrial cold storage complex is a prerequisite.
Tan Long Refrigeration and Electrical Engineering Joint Stock Company We are a leading and reputable EPC general contractor, specializing in design consulting and construction. Deep-freezing cellars for catfish, cold storage facilities for seafood, and cool storage for fruit preservation in Dong Thap.. We apply modern refrigeration technology standards, fire-retardant PIR panels (B1/B2), and a 24/7 SCADA monitoring system to optimize operating costs.

1. The Intensive Refrigeration Needs of Two Key Industries in Dong Thap Province
- Pangasius fillet for export (Sa Dec, Thanh Binh, Hong Nguy): After filleting and glazing, the product must be ultra-fast frozen via IQF conveyor belt or blast freezer. -35°C to -40°C For 45-60 minutes, allow the core temperature to reach -18°C. Then, transfer to a freezer storage facility. -22°C to -25°C, humidity 85% – 90% to prevent freezer burn.
- Chu Cat Mango & Hoa Loc Mango from Cao Lanh: After steam heat treatment (VHT) to kill fruit flies, mangoes need to be stored in a cold storage facility to lower their core temperature. +10°C to +12°C, with humidity of 85% – 90% To keep the stems fresh and green, and free from anthracnose throughout the export transportation process.
- Thap Muoi lotus seeds and lotus roots: We need a cold storage facility. +2°C to +5°C To keep lotus seeds fresh, white, and crispy, preventing them from turning black and fermenting into a sour paste.
