China cold storage solution provider
Pomelo is a popular citrus fruit enjoyed in many countries. To extend its shelf life and enable off-season sales, building a cold storage facility is an effective solution. In optimal conditions (3–5°C and 85–90% relative humidity), pomelos can be stored for 6–8 months while retaining freshness and flavor.
Below are the main factors that influence the cost of building a pomelo cold storage facility.
1. Storage Capacity
The overall size of the cold storage directly affects cost. Larger facilities require more insulation materials, refrigeration equipment, and accessories. On the other hand, very small cold rooms tend to have higher construction cost per cubic meter because the basic set of equipment is still required.
2. Temperature Requirements
Lower temperature settings require more powerful refrigeration systems and thicker insulation, increasing overall cost. For pomelos, the ideal storage temperature is 3–5°C, which slows respiration and reduces spoilage.
3. Insulation Panels
Cold room panels are usually made of polyurethane (PU) or polystyrene (EPS). PU panels offer better insulation and durability but cost more. The choice of insulation directly impacts both performance and service life.
4. Accessories & Components
Essential parts such as cooling towers, pumps, pipelines, liquid receivers, separators, and electrical systems vary in quantity and cost depending on cold room size.
5. Installation Costs
Labor, transportation, and site complexity affect installation expenses. Remote sites may require higher travel and logistics costs.
6. Refrigeration Equipment
Core equipment includes compressors, condensers, evaporators, and control systems. Imported brands generally cost more but provide better efficiency, durability, and reliability.
7. Geographic Factors
Location can influence both material costs and design requirements. For example, extremely cold regions may require additional heating systems to maintain stable storage temperatures.
Estimated Cost Range
In China, as a reference, a 1,000 m³ pomelo cold storage (3–5°C) may cost approximately USD 35,000–40,000, depending on configuration and brand of equipment.
