Not all cold rooms are created equal. The type you choose should match your specific industry, the products you store, and the temperatures required. In Kenya, several distinct types are in common use across food, health, and horticultural sectors.
1. Chiller Rooms (Positive Temperature Rooms)
Operating between 0°C and 8°C, chiller rooms are the most common type installed in Kenya. They are used for fresh produce, dairy, beverages, cooked foods, and medicines that need to stay cool but not frozen. They are less expensive to build and run than freezer rooms and are suitable for the vast majority of food businesses.
2. Freezer Rooms (Negative Temperature Rooms)
These operate between -18°C and -25°C and are used for meat, fish, ice cream, and any product requiring long-term frozen storage. They require thicker insulation panels, more powerful refrigeration equipment, and higher electricity consumption than chiller rooms.
3. Blast Freezers
A blast freezer rapidly drops product temperature from ambient to frozen — typically within 90 minutes to 4 hours depending on product mass. They are essential for exporters, fish processors, and anyone who needs to freeze fresh product quickly to preserve quality and comply with export regulations. Blast freezers are significantly more expensive than standard freezer rooms.
4. Controlled Atmosphere (CA) Rooms
Used primarily in Kenya’s horticulture industry, CA rooms regulate oxygen, carbon dioxide, and nitrogen levels in addition to temperature. This dramatically extends the shelf life of fruits, vegetables, and cut flowers. CA rooms are complex, expensive, and require specialist contractors.
5. Pharmaceutical Cold Rooms
These are precision chiller rooms built to GDP (Good Distribution Practice) standards, with validated temperature mapping, data logging, and backup systems. Required for hospitals, pharmacies, vaccine distributors, and biomedical facilities. Regulatory compliance is built into the design.
6. Modular Cold Rooms
Pre-fabricated and assembled on site from standardised panel kits, modular cold rooms are the most common type installed for small to medium businesses in Kenya. They are cost-effective, relatively quick to install, and can be expanded by adding more panels.
7. Walk-in Cold Rooms
A subcategory of modular rooms, walk-in cold rooms are large enough for staff to enter while stocking or retrieving goods. Most business-grade cold rooms in Kenya are walk-in by design.
8. Reach-in Cold Rooms
Smaller units — sometimes only 2–5 m² — designed for access from a single door without walking inside. Common in small restaurants, pharmacies, and laboratories.
For most Kenyan food businesses, a modular walk-in chiller or freezer room covers the requirement. Specialist applications — flowers, vaccines, export fish — need purpose-built solutions from contractors with relevant experience. Always specify your product type, required temperature, and compliance obligations before requesting a quote.
