📦 How Many Tons Can You Store?
A standard potato cold room operates at 4°C and 85% RH. With proper pallet racking and airflow:
| old Room Size | Usable Volume | Potato Storage Capacity* |
|---|---|---|
| 100 m² (5m height) | ～500 m³ | 80–90 metric tons |
| 300 m² | ～1,500 m³ | 240–270 metric tons |
| 600 m² | ～3,000 m³ | 480–540 metric tons |
Based on bulk storage in ventilated crates (density: ～180 kg/m³).
Includes space for forklift aisles and air circulation.
💰 Turnkey Investment (USD)
All systems include:
- 100mm B1 fire-rated PU panels (double-sided color steel)
- Refrigeration: Low-temp scroll compressors (e.g., Copeland), EC evaporators
- Humidity control: Ultrasonic humidifiers or wet-wall systems
- Smart monitoring: Remote alerts, data logging, mobile app
| Facility Size | Total Cost (USD) | Best For |
|---|---|---|
| Small (100 m² / ～85 tons) | 42,000 | Small farm co-op, local trader |
| Medium (300 m² / ～250 tons) | 68,000 | Regional aggregator, export prep |
| Large (600 m² / ～500 tons) | 120,000 | National distributor, processor backup |
✅ Turnkey includes: engineering, insulation, refrigeration, controls, installation

Designed for high ambient temperatures (up to 45°C)
🌍 Real Project: 280-Ton Potato Cold Storage – East Java, Indonesia
- Client: Farmer cooperative exporting to Singapore and Malaysia
- Challenge: 30% post-harvest loss during rainy season; no off-season sales capability
- Solution:
- 350 m² cold room @ 4°C / 85% RH
- 100mm PU panels + ultrasonic humidification
- Siemens remote monitoring with WhatsApp alerts
- Investment: $ 74,000 USD (turnkey)
- Results after 1 year:
- Spoilage reduced to <5%
- Stored potatoes for 5 months, sold at 47% higher price during dry-season shortage
- ROI achieved in just 10 months
- Now expanding to a second unit
🔑 Why Humidity Control Is Non-Negotiable
Potatoes shrink and sprout if RH <80%. Cheap systems skip humidification to cut costs—but that defeats the purpose.
✅ Professional potato cold rooms include:
- Ultrasonic humidifiers or evaporative pads
- Airflow design to prevent condensation on tubers
- CO₂ monitoring (optional) to suppress sprouting
Without proper humidity, you’re just building an expensive fridge—not a profit-preserving asset.
