Types of Cold Rooms In Nairobi – Kenya

We categorize Types of Cold Rooms In Nairobi – Kenya based on their temperature ranges and sizes, ranging from small walk-in to large warehouse-sized .

The cooling mechanism in a cold room operates similarly to other refrigeration systems to achieve and maintain low temperatures. Depending on the specific requirements and usage, cold room temperatures can range from -40°C to -2°C (-40°F to 28.4°F).

One of the primary benefits of cold rooms is their capability to offer temperature control for industrial applications that require long-term storage. They serve as an effective solution for preserving food products and chemicals.

The different types of cold rooms

We prefer cold rooms as the solution for storing products that require a consistently cold environment to preserve their integrity and optimal performance. Choosing the right cold room can be challenging due to the wide range of options available.  We design to accommodate various conditions and settings. Each business has specific needs to ensure the protection and safety of their products.

The selection process for a cold room starts with determining its required temperature range and size. The temperature range depends on the types and quantities of items for storage, while the size is based on the available space.

The Large cold rooms are in warehouses, fall into distinct categories and require careful custom design to meet specific operational needs.

How are cold rooms classified by temperature and size?

Cold rooms rely on refrigeration systems to maintain specific climatic conditions necessary for preserving products and supporting various manufacturing processes. They are crucial in industries where extremely low temperatures is a requirement. When selecting a cold room, considerations include its function, size, and temperature range, all of which influence the decision-making process.

Temperature Range

Positive Temperature Cold Room

Positive temperature cold rooms operate within a temperature range of 0°C to 18°C (32°F to 64.4°F). We use them for preserving the quality of fruits, vegetables, and medical samples such as tissue and medicines. These cold rooms ensure a stable environment for storing fresh food by maintaining a constant temperature.

We design this units for both manufacturing and preservation purposes. We equip them with various devices and thermometers to monitor and regulate the internal conditions and temperature of the room.

Negative Temperature Cold Room

Negative temperature cold rooms operate within a temperature range of 0°C to -28°C (32°F to -18.4°F). Achieving and maintaining these low temperatures requires high-quality insulation to minimize electricity usage and reduce the number of openings. These cold rooms are commonly in use for freezing and storing food, vaccines, and organic materials.

Deep Freezing Tunnel

Deep freezing tunnels operate at temperatures ranging from -30°C to -40°C (-22°F to -40°F). These tunnels use automatic displacement systems and cold air currents to freeze items as they pass through the tunnel. We design them to rapidly freeze products, deep freezing tunnels consist of a seal chamber through which food moves on a conveyor belt while being exposed to cold air that quickly freezes it.

In the deep freezing tunnel process, products are continuously transported by a series of conveyors. The key to this method is the high-speed circulation of cold air, which ensures uniform and rapid freezing.

Deep freezing tunnels were developed to address issues with previous freezing methods that caused ice crystals to form on products, affecting their texture and quality. The rapid freezing process of the tunnel minimizes ice crystal formation, preserving the product’s integrity and quality.

Temperature Blast Chillers

We design Temperature blast chillers to rapidly cool food products to safeguard them from bacterial growth, which can accelerate between 8°C and 68°C (46°F and 154°F). Similar to deep freezing tunnels, blast chillers use a high-speed circulation of cold air to quickly lower the temperature of the food products.

Chapter 4: What are the components of a cold room?

Cold rooms and clean rooms share similarities in that both require precise control over airflow and temperature. However, while clean rooms must maintain an environment free from contaminants, cold rooms focus on maintaining very low temperatures to preserve their contents.

The structure of cold rooms varies depending on their specific use, but all cold rooms share certain fundamental characteristics, including their refrigeration systems. Despite the variety in refrigeration systems, their operation generally follows a standard approach.

Flooring

The choice of flooring for a cold room depends on its temperature and specific needs. Flooring must endure freezing temperatures, be easy to clean, support heavy equipment, and be slip-resistant, stainless, and non-absorptive. Polyaspartic and urethane coatings are effective as they cure quickly even in cold conditions.

Panels

Cold room panels vary depending on the temperature rating of the cold room. An essential feature of these panels is their ability to prevent leakage and ensure a tight seal to minimize energy loss. They form the walls and ceilings of cold rooms and play a crucial role in temperature control and insulation, similar to panels used in clean rooms.

We construct Cold room panels  with a core of either polyisocyanurate (PIR), which offers highly efficient insulation, or polyurethane (PU), made using uniform dispersion molding (UDM). These panels are easy in installation and transport, being manufactured in manageable sections.

The key attributes of cold room panels include their lightweight nature, durability, and ease of handling.
