Professional Refrigeration Panels Supplier in China
Pupanel is committed to delivering high-performance refrigeration panels. Our refrigeration panel production equipment features a 36-meter-long double-track, providing sufficient aging reaction time for polyurethane foaming. It can also ensure stability over the long term.
PUR is a more common material for refrigeration panels; it has excellent thermal insulation and is durable enough to be used as walls, roofs, etc. in spaces that need refrigeration. It is also less costly.
PIR is a polyurethane blend with a high content of isocyanurate, which will have a more stable internal structure, better heat and fire resistance, and a slightly higher price than PUR refrigeration panels.
The main material of the PUF cold storage roof panel produced by Pupanel is lightweight rigid polyurethane foam; the outer panel can be a color steel or stainless steel plate. It has low thermal conductivity and can be used in cold-storage roofs, pharmaceutical storage, and food freezing, providing efficient refrigeration solutions.
Features of Refrigeration Panels
Pupanel refrigeration panels are made of foam and steel, which are strong and structurally stable enough to resist breakage or deformation during long-term use.
Refrigeration panels effectively insulate both air and water vapor, preventing rain and snow from entering the room and maintaining a stable humidity level in the space.
Refrigeration panels reduce heat and cold exchange between indoors and outdoors, reducing the burden on your cooling system and lowering long-term operating costs.
Pupanel offers a wide range of customization options to meet the needs of many projects. You can customize everything from panel thickness, size, core material, cut type, and more.
Environmentally Friendly Foaming Process
By abandoning the traditional F11 and 141B blowing agents, Pupanel’s refrigeration panel production process achieves zero fluorine emissions, making it truly environmentally friendly and non-polluting.
Safe and Fireproof
Using a new-generation PU PIR pentane foam (B1 grade) as the rigid core, the refrigeration panels offer excellent thermal and fire insulation, ultra-high temperature stability, and afire rating.
Customizable Articulation
Pupanel offers C/E/H-type cut-outs for refrigeration panels, enabling quick splicing and installation. It also guarantees a tight seal during subsequent use.
Applications of Our Refrigeration Panels
Pupanel refrigeration panels can be used for frozen or chilled storage of a wide range of food products, such as meat and fish, to ensure consistent quality over long periods.
In the storage of medicines, refrigeration panels can be used for the low temperature storage of vaccines, biological preparations, pharmaceuticals, and many other substances, to maintain the medicinal properties and activity and ensure the safety of use.
In cold chain warehouses and logistics centers, Pupanel refrigeration panels also maintain stable low temperatures during transport, meeting the needs of the cold chain for food, pharmaceuticals, and other goods.
In process rooms where low temperatures are required, our refrigeration panels insulate against water vapor and heat exchange, maintaining stable ambient temperatures and ensuring a smooth, orderly production process.
- Our Factory
- Project Case
Pupanel’s Refrigeration Panels, when used as a roof, are not only effective at insulating and waterproofing but also allow people to walk on them normally.
Refrigeration panels are better insulated, while ordinary architectural sandwich panels may be used for soundproofing, waterproofing, and similar applications; heat insulation is not their primary purpose.
Refrigeration Panels have two fire ratings: Category A and Category B. Category A is for non-combustible materials that cannot burn and therefore have a higher fire rating. while Category B is for flame-retardant materials, which generally slow down the spread of fire and reduce the intensity of flames to ensure safety.
Yes, Pupanel can provide you with detailed installation drawings or instructional videos. If you need on-site technical guidance, we can also send a professional engineer to your location to assist with the installation. You can rest assured of our experience; our technical team has traveled to Australia, Cameroon, Bolivia, Chile, Angola, Gabon, and other regions to provide services.
Our refrigeration panels are designed for long-term use and can last for decades with proper maintenance. We also offer surface finishing with anti-corrosive coatings if your application requires salt spray or other corrosive environments.
What Is a Refrigeration Panel?
Refrigeration panels are designed for applications such as cold storage and cold chain transport. They are suitable for storing and transporting frozen food and pharmaceuticals, and effectively maintain low temperatures to prevent product deterioration from elevated temperatures. They play a very critical role in today’s refrigeration applications.
Structure Of a Refrigeration Panel
Core Material
Refrigeration panels are also available with PUR or PIR core materials, which affect the overall thermal conductivity and cooling effect of the panels.
Metal Panels
The external metal panels are usually made of colored steel or stainless steel. Depending on the degree of corrosion and the application’s specific requirements, you can choose from various surface treatments, including galvanization and texturing, to enhance corrosion resistance or aesthetics.
Adhesive
The adhesive is also an important component, responsible for securely bonding the foam to the metal panel. Choosing a suitable adhesive will help ensure the panel is strong enough to resist bulging or delamination and remain durable.
Functions Of a Refrigeration Panel
Maintain Stable Temperature Inside
The main function of a refrigeration panel is to reduce the heat transfer between the outside and the inside, maintaining a stable, low temperature. This ensures the stability of the medicine’s properties in long-term storage.
Resist the Fire
Secondly, refrigeration panels also provide fire protection, which is an important consideration when purchasing. Its fire-retardant properties further ensure safety in use. It is particularly critical for the low-temperature storage of drugs and chemicals.
Insulate the Water
Its airtightness can also effectively block the flow of water vapor between indoor and outdoor spaces, preventing seepage and other issues and maintaining a consistent indoor humidity level. In low-temperature workshops, it also prevents water vapor from causing equipment corrosion and shortening the service life.
How To Choose a Proper Refrigeration Panel For Your Cold Storage?
Choosing The Right Core Material Based On Temperature Requirements
Your choice can be based on the cold room’s temperature requirements. For example, a cold room with a temperature range of 0-10 degrees Celsius can use PU refrigeration panels for daily food preservation, while a freezer at minus ten degrees Celsius may need PIR refrigeration panels to achieve lower temperature insulation requirements.
Choose Different Sheets According To Different Environments
The metal sheets used for the refrigeration panels can be selected based on the environment’s acidity or alkalinity.
For salty and alkaline environments, you can choose steel sheets with 180g of galvanized coating. In acidic or alkaline corrosive environments, the aluminum sheet’s corrosion resistance is improved, and you can choose a 150g galvanized coating.
Choose According To The Application Area
Depending on the application area, you can also choose different refrigeration panels. For example, for a medical cold room, you can choose PIR panels to provide insulation and a higher level of fire resistance. For large cold chain logistics centers, you can use a combination of PUF top panels and PU/PIR panels. If you only need the top panels, then PUF refrigeration top panels are sufficient.
Choose a Reliable Splicing Method
The heat sink’s splicing effect is evident at the edges. When splicing, ensure there is no gap between the two panels to prevent heat dissipation during use. At the same time, choose a heat sink that can be easily spliced to ensure a quick, efficient installation process, which is crucial for future replacement.
