Cold storage panel
Brief introduction
Cold storage panels - lightweight and high-strength integrated "refrigeration armor". The high-density polyurethane core material locks in the cold capacity, has a low thermal conductivity, and the cold bridge is almost zero. The tongue-and-groove and double layers of sealant form an airtight barrier, preventing moisture and water, leaving no place for cold air to escape. The surface is made of color steel or stainless steel, which is strong, pressure-resistant, bent and impact-resistant, yet lightweight, easy to assemble and shortens the quick-freezing period. A-level fireproof, non-toxic and odorless, smooth and antibacterial, clean with just one wipe, easily meeting the cleanliness standards for food and medicine. Energy-saving, environmentally friendly and durable, providing one-stop solutions for all kinds of cold storage enclosure needs.

Product advantages
Excellent heat preservation performance
The thermal conductivity is between 0.019 and 0.022w/m · k(at 25℃), which is the lowest among the insulation materials currently in practical application. It adopts high-pressure continuous foaming technology, with uniform and dense foaming. The closed-cell structure has small cells, with a cell density of up to 200,000 per cm³ and a closed-cell rate of over 97%. It has an extremely low water absorption rate and can effectively prevent the penetration of water vapor, thereby demonstrating its excellent thermal insulation and heat preservation performance.
Good fire resistance performance
Polyurethane rigid foam has excellent fire resistance. During combustion, it forms a caramelized protective layer and will not melt or drip like EPS and XPS. When combined with metal surface materials, its flame retardant performance can be further enhanced. The combustion performance meets the national standard 8624-2012 B1 grade.
The pentane technology is leading
One-time high-pressure foaming is carried out using fluorine-free raw materials, which does not produce chlorofluorocarbons, has a zero greenhouse effect, causes no pollution to the environment, complies with the international convention on the ozone layer, and meets European environmental protection standards.
Exclusive airtight technology
The proprietary board-type airtight structure technology is adopted to make the insulation layers of adjacent board joints more organically combined into one, forming a natural whole, eliminating the "cold vapor bridge", greatly improving the airtightness performance, and making it more suitable for controlled atmosphere storage.
Energy conservation, consumption reduction and environmental protection
The selection of materials and processing of polyurethane boards strictly follow national and industry environmental protection standards. During use, the board is not prone to bacterial and parasitic growth, making it suitable for various complex situations and strict environmental protection requirements in the cold chain industry. The cold storage insulation system with proprietary plate-type airtight structure technology organically integrates the cold storage body into one, achieving absolute airtightness, saving 30% of energy consumption and significantly reducing operating costs.
Easy and quick installation
The sheet materials are prefabricated in the factory, and the installation system is designed maturely to meet the requirements of all-weather construction.
Shorten the installation period, reduce labor costs and material waste.
Application field
Food cold chain: cold storage for fruits and vegetables, meat, dairy products, seafood, processing and sorting centers
Cold chain transportation equipment: walk-in freezers, refrigerated warehouses, refrigerated trucks, container mobile warehouses
Medicine and Life Sciences: Clean rooms, cool storage rooms, plasma storage rooms, vaccine storage rooms, GMP areas, and cold storage rooms for scientific research experiments
Business and public services: Supermarket combined cold storage, restaurant and hotel cold storage rooms
Installation Guide and Safety Precautions
1. Before installation
Recheck the flatness and elevation of the substructure. The moisture-proof layer should be laid in advance and the lap joints should be tight.
During the design stage, the penetration points of floor drains, lighting, evaporators, etc. are synchronously located to avoid on-site drilling later.
The construction environment temperature should be maintained above 5 °C to ensure uniform expansion of polyurethane and reliable bonding.
2. Panel assembly
A CAM lock or tenon groove system is adopted, and a tight connection can be achieved with a gentle push.
Stainless steel self-tapping screws, in combination with anti-corrosion sealant, form a continuous waterproof and thermal bridge barrier.
Angle steel brackets or sanitary arc cover plates are installed at the junctions of floors and walls or walls and ceilings to eliminate dead corners and facilitate cleaning.
3. Inspection after installation
Visual inspection + smoke method initial inspection, and the blower door test can be selected to verify the overall air tightness.
Infrared thermal imaging scanning is used to locate and repair potential cold Bridges.
Check whether the fireproof sealant around all service penetration parts is continuous and complete to ensure that the fire resistance rating has not been downgraded.
Introduction
Stainless steel cold storage panels are composite sandwich panels with 304 or 316 stainless steel as the panel and polyurethane as the insulation core. By taking advantage of the low thermal conductivity and high closed-cell rate of polyurethane and the corrosion resistance and easy cleaning properties of stainless steel, they have excellent heat insulation performance and durability, making them highly suitable for challenging environments. These panels are moisture-proof and have high strength. It provides efficient insulation and long-term protection for low-temperature Spaces, ensuring the quality of stored products and reducing operational energy costs. It is widely applicable to refrigeration, freezing and quick-freezing storage bodies with high requirements for hygiene and rust prevention in food processing, pharmaceutical cold chain, catering kitchens, etc.
