What is cold storage? New Era Cold Storage (NECS) is a specialized storage system, designed to maintain low temperatures, helping to preserve products effectively for long periods of time. Thanks to the application of modern technology, NECS has become the top choice of businesses. Let’s learn about the structure and main components that create the outstanding performance of this cold storage system.
1. What is cold storage? The difference between cold storage and regular storage
Cold storage can be understood as a specially designed type of warehouse that can adjust preservation factors such as temperature, humidity,… suitable for products that require strict conditions for preservation management.

Compare cold storage and regular storage
Element | Regular warehouse | Cold storage |
Temperature | Standard, uncontrolled conditions | Maintains low temperature (usually maintained -20oC) |
Role | Preserve goods that do not require low temperatures | Preserving goods with high temperature requirements such as pharmaceuticals, seafood, meat, fruit,… |
Equipment | There is no cooling system and little use of specialized equipment | There is a cooling system, insulation, and modern equipment |
2. Applications of frozen warehouses.
Freezing warehouses help preserve goods that require extremely low temperatures, typically maintained at -22°C, to prevent bacterial growth and maintain product freshness. Below is the explanation of what a freezing warehouse is:
- Helps preserve frozen products, seafood, agricultural products, fresh fruits and vegetables.
- Storage of vaccines, pharmaceuticals and medical products requires storage at low temperatures
- Preserving milk, supporting the preservation and fermentation process of beer

3. Structure of cold storage.
Many people may wonder about the structure of cold storage and how it affects the efficiency of product preservation. Below are the main components that make cold storage effective:
3.1. What is the structure of the warehouse’s insulation?
The warehouse shell is an important insulation part of the warehouse, made from large insulation panels, dividing the space into two parts: inside and outside. The panel has a smooth surface, two outer sides made from stainless steel or powder-coated corrugated iron, and a hard, lightweight, well-insulated, and durable foam core.

There are two commonly used types of panels: PU (Polyurethane) or EPS (Expanded Polystyrene). The size of the insulation panel will be selected or cut to suit the installation according to the design table.

3.2. What is the structure of a freezer warehouse door?
There are many types of cold storage doors with different sizes, such as hinged doors, sliding doors,… but must ensure the tightness of the warehouse, avoiding the loss of cold air when in use.
Doors are usually made from 304 stainless steel, with an insulating layer inside. The hinges and locking arms are made from our heart or stainless steel, reinforcing the strength and shine of the door.

- The surrounding joint structure helps prevent air loss to the outside
- The door frame has a multi-layer structure, is very solid and has an integrated drying resistor, to maintain dryness and cleanliness, and is easy to replace when needed.
3.3. Cooling system of cold storage
The refrigeration system helps maintain low temperatures and regulate humidity inside the warehouse. The structure of the refrigeration system will be different, depending on each type of product. Below are the components included in the cooling system:
- Compressor cluster: plays the most important role in the cold storage system. Has the function of compressing the refrigerant to reach high pressure, providing enough refrigerant and supporting the condensation process in the warehouse.

- Some common types of compressors such as: Piston, spiral, screw compressors,… are designed and operate according to different principles, depending on the purpose of use to choose the type of compressor. Compressors will be imported from abroad.
3.4. Hot and cold units of the warehouse
Hot and cold units will usually be divided into models corresponding to the warehouse’s usage temperature. The internal structure of the indoor unit must ensure sturdiness and high aesthetics.

Some important parts inside the air conditioner that you need to pay attention to when buying are: blades, fans that center, defrost resistor,… Like the compressor, the condenser and condenser are also imported complete units from abroad.
3.5. Cold storage control cabinet
What is the function of the cold storage control panel? It is a component that helps regulate temperature, humidity, and other technical parameters during the operation of the cold storage. This system can automatically adjust the temperature based on preset parameters. Inside the control panel are components such as the electrical cabinet, cold storage curtain, cold storage lighting, and more.
