China cold storage solution provider
Not all freezers are created equal. While standard cold rooms operate at -18°C, premium seafood like tuna, snow crab, or spot prawns requires storage at -60°C to preserve texture, color, and freshness for months—even years.
But ultra-low temperature comes at a price. Clients often ask:
✅ What’s the total cost?
✅ How much high-value seafood can it actually hold?
📦 Storage Capacity: How Much Can You Store?
| Parameter | Specification |
|---|---|
| Floor Area | 50 m² (e.g., 5m × 10m) |
| Ceiling Height | 3.0 m |
| Total Volume | 150 m³ |
| Estimated Storage Capacity | 25 – 35 metric tons of frozen seafood |
Based on standard cartons (10–15 kg each), stacked 6–7 layers high. Ideal for bluefin tuna loins, king crab legs, or frozen lobster tails.
This type of freezer is commonly used by seafood exporters, luxury distributors, or research labs handling high-value marine products.
💰 Total Investment: What You Actually Pay
A fully installed, turnkey 50m² -60°C ultra-low temperature freezer—including insulation, refrigeration, controls, and commissioning—typically costs:
70,000– 100,000 USD
✅ This is a complete system, ready to operate on day one.
Key System Specifications:
- Insulation: 300mm (30 cm) thick polyurethane (PU) panels — essential for -60°C stability
- Refrigeration: Cascade condensing unit (two-stage system using R-404A / R-23 or eco-friendly alternatives)
- Air Distribution: Ceiling-mounted low-temperature evaporators with defrost control
- Control System: Digital PLC with temperature logging, alarms, and remote monitoring
- Doors: Heavy-duty insulated sliding or hinged doors with heated frames to prevent freezing shut
💡 Due to extreme temperatures, installation must follow strict thermal-break and sealing protocols—cutting corners risks system failure.
