Together with the pipework, valves, ancillary equipment and a complete NH3 refrigeration system.
Why the system uses NH3 as the refrigerant
NH3 (ammonia) is the most widely used refrigerant in large-scale plants and cold stores in Vietnam. Three engineering reasons:
- The highest cooling efficiency among the common industrial refrigerants, in the evaporating temperature range from -18°C to -40°C.
- Low operating cost: the refrigerant is inexpensive and its high efficiency reduces electricity use per tonne of goods.
- No ozone depletion and no direct greenhouse effect.
In return, NH3 demands a higher standard of safety capability: leak detection sensors, emergency ventilation systems and strict operating procedures. This is the technical barrier that means not many contractors in Vietnam have mastered plant-scale NH3 systems.
What the project demonstrates about Tan Long's capability
12 of the 21 equipment packages on the project were fabricated by Tan Long itself at its plant in Duc Hoa 1 Industrial Park, Tay Ninh (formerly Long An). This is what sets it apart from the trading-contractor model of buying equipment in and fitting it.
Fabricating in-house brings three direct benefits to the client:
- Control over the schedule: no dependence on import delivery dates.
- Customised to the floor plan: equipment dimensions and configuration designed around the actual workshop space.
- Fast repair and replacement: materials, drawings and the fabrication team are all available in-country.
Frequently Asked Questions
Which work packages did Tan Long deliver at Vietnam Clean Seafood?
Tan Long designed, supplied and installed an NH3 refrigeration system for Vietnam Clean Seafood JSC at An Nghiep Industrial Park, Soc Trang Province. The equipment handed over comprises: IQF belts (Mycom): 03 units; IQF belts 1,200 kg and 1,000 kg + re-freezing (Tan Long): 02 units; contact plate freezers 1,000 kg per batch (Tan Long): 02 units; air blast freezer 300 kg per batch (Tan Long): 01 unit; flake ice machines 30 tonnes (Tan Long): 04 units; flake ice machines 20 tonnes (Tan Long): 04 units; and 15 further packages.
Which refrigerant does the refrigeration system at Vietnam Clean Seafood use?
The system uses NH3 as its refrigerant. NH3 delivers the highest cooling efficiency among the common industrial refrigerants in the evaporating temperature range from -18°C to -40°C, has a low operating cost and does not deplete the ozone layer. In return, NH3 demands a higher standard of safety capability: leak detection sensors, emergency ventilation and strict operating procedures.
Which equipment on the project was manufactured in-house by Tan Long?
On this project, 12 equipment packages were fabricated by Tan Long itself at its plant in Duc Hoa 1 Industrial Park, Tay Ninh — not bought in from a third party. This is what sets it apart from the trading-contractor model.
Can Tan Long deliver a similar project for another plant?
Yes. Tan Long has designed, fabricated and installed industrial refrigeration systems for 29 projects in Vietnam, including seafood, food and beverage processing plants and cold chain logistics centres. See full project list or call 0933 357 058 (Mr. Thinh) for advice.
