Ninh Thuan is the largest shrimp hatchery center in Vietnam. Ca Na, An Hai (supplying over 351 TP3T to meet the nationwide demand for shrimp larvae) along with a unique specialized area for growing grapes and green apples. Phan Rang – Thap Cham, Ninh Phuoc, Ninh Hai. Located in the hottest and windiest climate zone in the country, with outdoor temperatures frequently reaching 38°C – 40°C, shrimp hatcheries and specialty fruit wholesalers in Ninh Thuan face severe challenges in controlling temperature and humidity.
Tan Long Refrigeration and Electrical Engineering Joint Stock Company We are a leading and reputable EPC general contractor, specializing in design consulting and construction. Cold storage for broodstock shrimp, chilled storage for grapes and apples, and a seafood freezing complex in Ninh Thuan.. Tan Long's refrigeration and air conditioning system utilizes Inverter cooling technology, offering superior energy savings and maintaining stable temperature and humidity levels even in harsh weather conditions.
1. Specific Refrigeration Requirements in Ninh Thuan Production Regions
- Ca Na & An Hai shrimp hatchery area: Broodstock shrimp (imported tiger shrimp, whiteleg shrimp) and live shrimp feed (sea cucumbers, fresh squid) must be stored in ultra-low temperature cold storage (-20°C to -25°C) to completely eliminate EHP pathogens and bioluminescent bacteria before mixing.
- The grape-growing regions of Phan Rang, Ninh Phuoc, and Ninh Hai: Red Cardinal red grapes and NH01-48 green grapes have thin skins and soft stems that easily fall off after harvesting. If left at an outdoor temperature of 35°C, the grape bunches will lose water, wilt, and ferment into sour grapes within 48 hours. A cool storage environment is necessary to maintain optimal temperatures for grapes. 0°C to +2°C, with humidity of 90% – 95% Combines a gentle convection fan system.
- Ca Na, Dong Hai, and My Tan fishing ports: The rich fishing grounds receive thousands of tons of squid, anchovies, and skipjack tuna daily. The deep-air blast freezing tunnel system utilizes negative pressure. -35°C to -40°C This is a prerequisite for preserving the quality of seafood before it is processed in factories for export.

7. Frequently Asked Questions (FAQ)
1. Will the stems of Phan Rang grapes fall off if stored in cold storage?
No, if the humidity is controlled at 90% – 95% and the air circulation speed is gentle (below 0.3 m/s). Tan Long designed a special indirect-blowing cooling system to keep the grape stems supple and intact.
2. In the Ca Na area, where the sea breeze is very salty, will the air conditioner unit break down quickly?
Tan Long uses cooling coils with Blue Fin/Gold Fin anti-corrosion coating or 304 stainless steel copper tubes resistant to seawater salt, and provides a warranty of up to 2 years for the heat exchanger.
