As global demand for fresh, safe, and long-lasting food grows, the importance of cold storage solutions becomes more critical than ever. At Colderman, with exports to more than 90 countries, we specialize in designing and delivering customized cold room systems tailored to various climate conditions and storage needs.
In this article, we will explore how to select the right cold room for storing different types of vegetables and food products, including optimal storage temperatures, environmental conditions, and an example case study for leafy greens like lettuce.
Optimal Storage Temperatures for Common Produce:
| Product Type | Recommended Storage Temperature | Humidity (%) |
| Leafy Greens (Lettuce, Parsley) | 0–2°C | 95–98% |
| Tomatoes | 12–15°C | 85–90% |
| Potatoes | 4–7°C | 90–95% |
| Apples | 0–4°C | 90–95% |
| Carrots | 0–2°C | 90–95% |
| Bananas | 13–14°C | 85–90% |
| Fish | -2 to 0°C | 85–90% |
| Poultry | -1 to 2°C | 85–90% |
Environmental Considerations for Cold Room Design
To maintain consistent cooling performance, the external ambient temperature and insulation quality of the room are key factors. For hot climates (above 35°C), cooling systems must be designed with:
- Oversized condenser units to combat heat load
- Proper insulation (minimum 10 cm polyurethane panels)
- Double-door sealing systems to prevent warm air ingress
- Humidity control systems, especially for fresh produce
Cold Room Equipment Selection Based on External Temperatures
| Ambient Temperature | Cooling Unit Capacity Increase |
| Up to 25°C | Normal capacity |
| 25–35°C | +15–20% larger capacity |
| Above 35°C | +25–30% larger capacity |
Sample Case Study: Storing 100 Crates of Leafy Greens (Lettuce)
Let’s assume each crate is approx. 60 × 40 × 25 cm and contains 10 kg of product.
Total product weight = 100 crates × 10 kg = 1,000 kg
Recommended conditions:
- Storage Temperature: 0–2°C
- Humidity: 95–98%
- Room Size: Approx. 12–15 m³ (suggested 3m × 2m × 2.5m)
- Cooling Capacity Required: ~2.5–3.0 kW (depending on ambient temp)
- Insulation: 10 cm PU panel
- Daily Door Openings: Medium → Suggest installing air curtain or plastic strips
