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

4 of the 10 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 Ca Mau Seafood Processing and Services?

Tan Long designed, supplied and installed an NH3 refrigeration system for Ca Mau Seafood Processing and Services JSC at 04 Nguyen Cong Tru, Ca Mau City, Ca Mau Province. The equipment handed over comprises: REF re-freezing belts 780 kg/h (Tan Long): 04 units; contact plate freezers 1,500 kg (Tan Long): 02 units; piston compressor packs (Grasso): 04 units; air coolers (Güntner): 14 units; piston compressors N62M (Mycom): 02 units; evaporative condenser 350 kW (Tan Long): 01 unit; and 4 further packages.

Which refrigerant does the refrigeration system at Ca Mau Seafood Processing and Services 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, 4 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.
