Above zero cold storages are controlled environments that keep stored products at a temperature above freezing. These types of storages are used for preserving perishable goods such as fruits, vegetables, and medicines that require low temperatures without freezing to maintain quality and shelf life.
In designing and constructing above zero cold storages, selecting the right refrigeration equipment is of utmost importance. Tabadol Gostar Booran, with extensive experience in manufacturing and supplying refrigeration equipment such as different types of cold storages, freezing tunnels, ice banks, condensers, and compressors, can be an ideal choice for meeting your project’s refrigeration needs.

Above zero cold storage is a controlled environment with a temperature above 0°C, used for storing various food products such as fruits, vegetables, dairy products, as well as pharmaceuticals and some industrial materials.
This type of storage, also known as a fruit cold storage, provides ideal conditions for maintaining the freshness and quality of agricultural products.
The temperature of above zero cold storage can range from 0°C to 15°C depending on the type of product stored. Additionally, these storages are widely used in different industries as industrial cold storages to preserve raw materials and finished products at appropriate temperatures.
Above zero cold storages use refrigeration systems to keep the internal temperature lower than the outside environment. The refrigerant absorbs heat from the storage, evaporates, and reduces the temperature. It is then compressed by the compressor and condensed back into a liquid, releasing heat outside. This cycle repeats continuously to maintain a stable internal temperature.
Feature | Above Zero Cold Storage | Below Zero Cold Storage |
|---|---|---|
Temperature | Above 0°C | Below 0°C |
Application | Preserving fruits, vegetables, dairy, medicine | Preserving meat, fish, frozen goods |
Equipment | Compressor, evaporator, temperature & humidity control systems | Similar equipment but with different capacity requirements |
Insulation | Highly important | Highly important |
Above zero cold storages, by creating a controlled environment with suitable temperature, play a key role in maintaining product quality and extending shelf life. With precise temperature and humidity control, they prevent early spoilage and minimize waste.
The ideal storage conditions also help preserve the original taste and texture of products, ensuring long-term quality.
Their flexibility in adjusting temperature and humidity makes them suitable for storing various types of products, turning them into an essential part of the food and pharmaceutical industries.
Fixed above zero cold storages, due to their permanent structure and high capacity, are commonly used in warehouses, food production factories, and food distribution centers. They are ideal for long-term storage of large volumes of products such as fruits, vegetables, dairy, and other food items. Since these storages are fixed, they can be designed and equipped according to the specific needs of each business.
Mobile above zero cold storages, designed as containers or trailers, are very practical for transporting products over long distances. Due to their mobility, they provide high flexibility in logistics and distribution.
Food and pharmaceutical transport industries are the main users of this type of storage. With strong insulation and advanced cooling systems, they ensure optimal product quality during transit.
Industrial above zero cold storages are typically used for storing a wide range of products including fresh fruits and vegetables, dairy products, pharmaceuticals, vaccines, and temperature-sensitive chemicals. Their design often varies depending on the specific requirements of the industry.
The design of above zero cold storage begins with identifying the exact project requirements such as product type, storage volume, desired temperature, and required dimensions.
Next, a suitable location with good accessibility must be selected. Proper insulation and sufficient power supply are also crucial.
Then, detailed plans for the structure, refrigeration system, and insulation are prepared to determine the appropriate equipment including the cold storage compressor, evaporator, and temperature/humidity control systems.
After finalizing the design, the construction and installation processes begin, followed by careful testing and calibration of the refrigeration and temperature control systems.
Specialists constructing above zero cold storages must strictly follow hygiene, safety, and energy efficiency standards.
For example, by using:
Proper and professional implementation of an above zero cold storage requires following specific technical and engineering guidelines. One of the most important factors is using high-quality thermal insulation to prevent heat transfer between inside and outside.
This reduces energy consumption and maintains a stable internal temperature. Additionally, selecting cooling equipment with suitable capacity based on environmental conditions and storage volume is crucial. Proper installation of this equipment ensures optimal system performance.
The main element of the refrigeration system, which increases the refrigerant gas pressure, raises its temperature, and ensures its circulation in the system. It converts mechanical energy into thermal energy and directs the refrigerant to the condenser.
The evaporator is where the refrigerant evaporates and absorbs heat from the environment, cooling the internal space. This heat exchange process lowers the temperature and generates cold air.
Cold storage condenser, where the compressed refrigerant releases its heat to the outside environment, turning the gas into liquid. This process helps cool the refrigerant and prepares it to enter the evaporator.
These devices send data related to temperature and humidity to the central control system, which then issues the necessary commands to regulate the compressor’s performance.
Thermostats and hygrometers continuously measure the internal temperature of the cold storage and send signals to the compressor to maintain the desired temperature. Humidity is also controlled by hygrometers to prevent the growth of fungi and bacteria.
One of the most important factors in maintaining stable temperature is the doors. Cold storage doors must have strong insulation and proper sealing systems to prevent warm air from entering the storage.
To ensure product security and prevent unauthorized access, security systems such as alarms, CCTV cameras, and access control systems are installed. Additionally, for proper organization and easy access to products, shelves and pallets with ergonomic design and durable material are used to prevent product damage.
The cost of constructing an above zero cold storage depends on your specific needs. Various factors such as capacity, type of products, and environmental conditions affect the final price. Therefore, it is recommended to contact Tabadol Gostar Booran experts for professional consultation and after-sales services.
The cost of building a cold storage above zero depends on multiple factors. These include the type of product to be stored, the required precision of temperature and humidity control, the type of control system, and the construction and insulation materials used. The more sensitive the product, the more advanced and costly the equipment required will be.
When purchasing an above zero cold storage, it is important to consider factors such as product type, storage volume, required temperature, and the manufacturer. To ensure quality and performance, it is best to purchase from reputable and experienced companies. Also, pay attention to warranties and after-sales services.
