China cold storage solution provider
Different types of freezer rooms operate at different temperature levels depending on the products being stored. For international buyers, the key concerns are always the same:
What temperature should the freezer room run at? How much does it cost to build? How much can it store?
1. Common Temperature Standards for Low-Temperature Freezer Rooms
1. -18°C Freezer Room (Frozen Meat Storage)
- Standard temperature: -18°C (±5°C adjustable)
- Used for storing meat that has already been rapidly frozen at -35°C.
- Ensures long-term storage without texture loss.
2. -30°C to -35°C Blast Freezer Room
- Temperature range: -30°C to -35°C
- Used for rapid freezing of food, seafood, fruit, and raw materials.
- High freezing speed = better taste and less drip loss.
3. Ultra-Low Temperature Freezer Room (-60°C to -80°C)
- Temperature range: -60°C to -80°C
- Used for tuna, sashimi-grade seafood, biological samples, and pharmaceuticals.
- Maintains cellular integrity for premium seafood export and lab storage.
4. Special Freezer Rooms (-100°C and below)
- Temperature: -100°C to -120°C
- Used for environmental simulation, research labs, and special biological materials.
2. How Much Does It Cost to Build a Low-Temperature Freezer Room?
Cost varies by temperature requirement, insulation thickness, compressor configuration, and project location.
General pricing (converted from RMB → USD):
| Freezer Type | Temperature | Cost per m² (USD) | Notes |
|---|---|---|---|
| -18°C Freezer Room | -18°C | $360–380 / m² | Most common frozen storage |
| -35°C Blast Freezer | -30°C to -35°C | $480–580 / m² | Higher-capacity refrigeration |
| -60°C Tuna Freezer | -50°C to -60°C | $800–1200 / m² | Premium insulation required |
| -80°C Ultra-Low Room | -70°C to -80°C | $1500–2000 / m² | Lab-grade system |
Example:
A 100 m² -35°C blast freezer typically costs:
➡️ USD 48,000 – 58,000
(including panels, compressors, evaporators, electrical system, installation, and testing)
3. Storage Capacity of Low-Temperature Freezer Rooms
Storage volume depends on room height (usually 3–4 m):
Example: 100 m² freezer room
- Volume: ~350 m³
- Storage capacity:
- Frozen meat: 65–90 tons
- Seafood: 55–80 tons
- Blast-frozen food: 50–70 tons
- Pallets: 80–120 pallets
4. Electricity Consumption
Typical energy consumption for low-temperature freezer rooms:
- -18°C freezer: 45–65 kWh per ton per day
- -35°C blast freezer: 70–110 kWh per ton per day
- Ultra-low: -60°C to -80°C: 120–180 kWh per ton per day
Good engineering design reduces power usage by 10–18%.
Investment & ROI Example
A client in Santiago, Chile built a 150 m² -35°C blast freezer room for frozen beef and seafood export.
- Investment Cost: ~USD 78,000
- Storage Capacity: ~75–95 tons after blast freezing
- Energy Consumption: 75–110 kWh per ton per day
- Payback Period: 1.5–2.3 years, thanks to high demand for frozen beef and strong export margins
