Tan Long was responsible for the design, supply and installation of the refrigeration systems for the whole the Lotte F&G Vietnam plant at Long Hau Industrial Park, Tay Ninh (formerly Long An) — covering the freezing lines, the freezer store, the chill store and the production hall air conditioning.
This is a rare project running three different refrigerants in the same plant at the same time: CO2, NH3 and R404.
Project summary

What Tan Long's scope covers
- System design: calculating the cooling load, selecting the compressor configuration, designing the refrigerant pipework and laying out the equipment to suit the plant floor plan.
- Supply of imported equipment: IQF conveyor, screw compressors, industrial air coolers, air conditioning FCUs.
- Installation, commissioning and acceptance: connecting the whole system, charging refrigerant, balancing and handing over for operation.

Together with the pipework, valves, ancillary equipment and the complete CO2, NH3 and R404 refrigeration systems.
Why the system uses CO2, NH3 and R404 as refrigerants
The Lotte F&G Vietnam plant runs three refrigerants at once because each suits a different temperature band and a different problem:
- NH3 for the large cooling loads: the highest efficiency and the lowest operating cost, suited to freezing and freezer storage.
- CO2 for the very low temperature zones: it operates at high pressure but is safer than NH3 where it runs into areas with people working.
- R404 for the small, standalone units, where installing a central system is not economical.
Designing a system that combines three refrigerants demands rigorous cooling-load zoning calculations and a far higher standard of safety capability than a single-refrigerant system. Very few contractors in Vietnam can deliver this configuration.
What the project demonstrates about Tan Long's capability
On this project, the value Tan Long brought lies in its system integration capability: calculating the cooling load zoning, bringing equipment from several different manufacturers (Mycom, Güntner, Thermowave, JBT) together into one system operating as a whole, and ensuring the safety of a multi-refrigerant arrangement.
On other projects, Tan Long also fabricates IQF belts, contact plate freezers, flake ice machines and evaporative condensers in-house at its plant in Duc Hoa 1 Industrial Park, Tay Ninh.
Frequently Asked Questions
Which work packages did Tan Long deliver at the Lotte F&G Vietnam plant?
Tan Long designed, fabricated, supplied and installed complete CO2, NH3 and R404 refrigeration systems for Lotte F&G Vietnam Co., Ltd at Long Hau Industrial Park, Tay Ninh. The imported equipment includes the IQF belts, screw compressors and industrial air coolers.
Which refrigerants does the refrigeration system at Lotte F&G Vietnam use?
The system uses CO2, NH3 and R404 as refrigerants. Combining three refrigerants allows operating costs to be optimised for each temperature band within the plant.
How large is the Lotte F&G Vietnam project?
Refrigerant: CO2, NH3, and R404. Freezing Capacity IQF: 2,600 kg/hour. Heat exchanger: 46 evaporators and Güntner FCUs. Air conditioning capacity: 1,510 kW.
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.
