Building a cold storage facility capable of maintaining -40°C falls into the ultra-low temperature category. Such projects require strict engineering standards, premium insulation materials, and specialized refrigeration systems. As a result, the investment is significantly higher than for conventional cold storage.
Below are the main factors that determine the construction cost of a -40°C ultra-low temperature cold storage facility:
1. Insulation Materials
For -40°C applications, 150mm thick polyurethane insulation panels are recommended.
- Advantages: Excellent thermal performance, low energy loss, long service life
- Disadvantage: Higher cost compared to polystyrene panels
Insulation quality has a direct impact on both the initial construction budget and long-term operational expenses.
2. Refrigeration Units
The compressor is the core of the refrigeration system, and for -40°C storage, it must be powerful and reliable.
- Recommended types: Semi-hermetic piston compressors, two-stage compressors, semi-hermetic screw compressors
- Popular brands: Bitzer (Germany), Copeland (USA), Hanbell (Taiwan)
Imported units generally cost more than domestic ones but provide better efficiency, durability, and stability.
3. Refrigeration Accessories
Accessories typically account for around 30% of the total construction cost. Using premium imported components can improve cooling performance and extend lifespan.
- Common brands: Danfoss (USA), Alco (USA), Carly (France)
High-quality accessories ensure stable ultra-low temperature operation but increase the overall investment.
4. Storage Size
The total investment rises with the size of the cold storage. However, smaller facilities usually have a higher per-cubic-meter cost because essential equipment must still be included regardless of size.
5. Location
Site selection is critical. The facility should be built in a dry area with good drainage, reliable power supply, and convenient transport access.
Poor location choices can lead to higher operating costs, such as increased utility and logistics expenses.
Conclusion:
The exact cost of constructing a -40°C ultra-low temperature cold storage depends on design specifications, materials, equipment brands, and site conditions. To obtain an accurate quotation, a professional site inspection and engineering plan are recommended.
