Features of Cold Storage Panels
The cold storage panel has excellent thermal insulation and can retain cold for a long time.
The sheet material has excellent sealing properties, preventing cold bridges and condensation.
The closed-cell core material is non-absorbent and therefore can be used for a long time in areas with high humidity and low temperatures.
The structure’s strength is very high; it will not change shape, making it perfect for large-scale cold storage applications.
Modular design, quick installation, and reduced project duration.
The surface is corrosion-resistant and easy to clean, making it suitable for food and pharmaceutical cleanliness requirements.
Different thicknesses are provided to meet the varying temperature requirements for cold storage, freezing, and quick freezing.
The product has a long service life, requires infrequent maintenance, and has an overall cost that is more controllable.
Good Heat Preservation Effect
The special cold storage panels are made with a BASF core material with very low thermal conductivity. As a result, the convective exchange between the hot external air and the cold air inside the cold storage is significantly reduced. Your total heat loss can be greatly minimized, and at the same time, the compressor running time and the refrigeration motor energy consumption can be lowered. The shelf life of your materials will also be significantly extended.
Great Sealing Performance
The panel of the refrigerator compartment features a unique locking mechanism and sealing design. It can completely eliminate cold bridges, condensation, and water vapor ingress during the cooling process in the freezer compartment; hence, insulation failure, freezing, or panel corrosion due to moisture will no longer be a problem. It can maintain a dry atmosphere inside your refrigerator over the long term, thereby greatly prolonging the life of the cooling plates.
High Structural Strength
The refrigeration room panel can have both characteristics. The middle layer employed a hard-foam high-density core, and the outer layer used metal panels, making it very resistant to impact and bending. During the operation of the refrigeration room, there will be very few chances of the panel being deformed or damaged, thus significantly reducing maintenance and replacement costs.
Applications of Cold Storage Panels
Create a stable thermal-insulation enclosure that prevents heat loss.
Lower the amount of heat exchanged at the top and the occurrence of condensation.
Effective separation of temperature zones is achieved.
Coldness is prevented from going down through the floor.
They should seal well, even when opened and closed frequently.
Enclosure panels in low-temperature operating areas of food processing workshops to eliminate heat loss.
- Our Factory
- Project Case
Our refrigeration board is designed with a sealed structure that prevents condensation or frosting during normal use. During your usage, as long as you don’t frequently open the freezer door and reduce the air exchange between inside and outside, this problem will not occur.
For the panels used in the refrigeration compartment, PU (polyurethane) and PIR (polyisocyanurate) are better choices. These two types of foamed rigid materials have lower thermal conductivity, which can significantly reduce heat loss from the cold storage facility. And the cost is very low, making it an economical and practical option.
Yes. The thickened refrigeration board can better reduce convection of hot air and minimize cooling capacity loss. Especially in situations with a significant temperature difference between inside and outside, choosing a thicker refrigeration panel can help reduce your refrigeration motor’s energy consumption.
Although the temperature in the cold storage is relatively low, refrigerant leakage could still pose a fire risk. Therefore, the panels used in the cold storage also need to comply with fire safety regulations. Our cold storage partition boards have a fire resistance rating of B1 or above, which can effectively help you solve this problem.
Step 1: Clear the ground near where the cold storage panels are installed to keep it level
Step 2: Use screws to fix the U-shaped groove to a flat surface. These kits will be distributed to you together after you purchase the door panels.
Step 3: Install and embed the floor refrigeration board into the U-shaped groove. Install the wall panels in sequence and finally place the ceiling in the groove at the top of the wall panels.
Step 4: Insert the door frame into the remaining reserved holes, and finally cut the door panel to the appropriate size and place it in.
Step 5: All inner and outer seams should be sealed with sealant and rivets.
Cold Storage Panels: A Practical Guide for Industrial Projects
What Is a Cold Storage Panel?
The Cold Storage Panel is recognized as a superior composite sheet designed solely for cold storage, refrigerated rooms, and low-temperature storage areas. The structure comprises two sheets of metal, with a core material of choice sandwiched between them. These layers are united with sealant and a modular locking system for a solid structure that provides excellent insulation and, at the same time, achieves waterproof and moisture-proof properties.
The core of the panel may be selected from several choices, including polyurethane (PU), polystyrene (XPS), rock wool, or a honeycomb structure. Besides considering insulation, fire resistance, sound insulation, and load-bearing performance, the refrigeration board will be lightweight and easy to install, making it ideal for various cold chain engineering applications, such as food, medicine, and logistics.
The panel surface is at the same time corrosion-resistant and easily cleaned, resulting in lower maintenance costs over the long term. The refrigeration board is the best option for you to have an energy-saving, efficient, and safe storage facility, regardless of the size, whether small cold storage or large industrial cold storage.
How does a Cold Storage Panel System Maintain Low Temperatures?
The insulated panels for cold storage maximize the insulation effect of the refrigerator’s cold air. The insulation improvement is mainly due to the cooperation of different factors:
- The middle part of the cold storage panel is composed of a superior insulation material with a higher thermal resistance than the regular materials used.
- A precise joint system and mortise-slot connection are used to obtain an excellent sealing performance.
- An airtight seal is applied to the seams, preventing external moisture from entering the cold storage.
What Thickness of Cold Storage Panel is Required?
Regular refrigerator compartment panel (around 0℃): 80mm.
Freezer compartment plate (-20℃ – 1℃): 100 – 140mm.
Quick-freezing chamber plate (-40℃): 150-200mm.
