How Much Does It Cost to Build a 4000㎡ Low-Temperature Cold Storage for a Food Factory?

For large-scale food factories, building cold storage is essential for keeping raw materials safe and fresh. For example, seafood processing plants require low-temperature cold rooms for storage, while frozen tunnels and blast freezers are used for rapid freezing. Especially in coastal regions, there is strong demand for constructing large-scale low-temperature cold storage facilities. Recently, one of our clients asked about the estimated cost of building a 4000㎡ cold storage in a food factory.

Estimated Cost of a 4000㎡ Low-Temperature Cold Storage

Based on standard design parameters, the overall construction cost of a 4000㎡ cold storage project is roughly 3.5–4.5 million RMB (approx. USD 480,000–620,000).
This estimate includes cold rooms for refrigeration, freezing, and blast freezing. The exact price per square meter may vary depending on design requirements, equipment selection, and construction methods.

Typically, polyurethane (PU) insulation panels are used for the structure, while screw compressor parallel units, water-cooled or air-cooled systems may be chosen depending on project needs. Since many factors influence the total budget, the final cost can only be determined after a tailored design proposal.

Key Factors Affecting Cold Storage Construction Cost

1.Scale and Layout

• The larger the cold storage area, the lower the average cost per square meter.
• However, more divisions/partitions increase material and equipment requirements, thus raising costs.
• Final pricing depends on the detailed design layout.

2.Refrigeration Equipment & Brand

• Equipment selection depends on target temperature, cooling speed, warehouse size, and ambient environment.
• Options include fully enclosed condensing units, open-type compressors, parallel compressor racks, and screw compressor systems.
• Costs vary greatly between different brands and models.

3.Construction Type & Insulation

• Cold storage can be built inside brick-concrete warehouses (with sprayed insulation) or steel structure buildings (with panel assembly).
• Different construction methods lead to significant differences in cost, efficiency, and durability.
