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
1 of the 5 equipment packages on the project was 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 Anh Duong Irradiation Technology?
Tan Long designed, supplied and installed an NH3 refrigeration system for Anh Duong Irradiation Technology JSC at Lot 22, Road N7, Long Thanh High-Tech Industrial Park, Dong Nai. The equipment handed over comprises: screw compressors (Mycom): 05 units; evaporative condensers (Tan Long): 02 units; air coolers (Güntner): 20 units; loading dock doors (DoorHan): 19 units.
Which refrigerant does the refrigeration system at Anh Duong Irradiation Technology 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, 1 equipment package was 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.
