Premium insulated panels manufactured by Shanghai Heleng Refrigeration and Electromechanical Equipment Co., Ltd. provide high-efficiency thermal barriers. They serve as a critical component of our comprehensive cold chain engineering. These high-performance polyurethane sandwich panels integrate seamlessly with our advanced refrigeration equipment. This includes top-tier compressor units from Bitzer, Fusheng, and Heron. By combining superior insulation with optimized machinery, we deliver robust turnkey systems. Our solutions dramatically reduce operational energy costs. They also guarantee precise temperature control and minimize maintenance for global facilities.
We understand that a cold room is only as reliable as its weakest joint. That is why our cold storage panels are explicitly designed to prevent thermal bridging and air leakage. You might be building a small commercial walk-in chiller. Or, you may require a massive industrial distribution facility. Choosing our premium enclosures ensures your cooling equipment operates at peak efficiency. This minimizes runtime and directly protects your bottom line.
At HELENG, we utilize advanced manufacturing techniques to produce highly durable polyurethane panels. They are carefully tailored to meet diverse structural and sanitary requirements. Our state-of-the-art production line applies precise temperature and pressure controls. This guarantees a perfect bond between the protective outer skin and the rigid core. It effectively eliminates the risk of delamination over decades of rigorous service. We offer several high-performance skin material options based on your facility's operational environment. These specialized options enhance structural integrity, resist corrosive atmospheres, and facilitate easy sanitation.
For standard cold storage projects, we offer prepainted galvanized steel and stainless steel skins. We primarily utilize SUS304 or SUS316 grades. These durable metal surfaces are highly favored in hygienic food preparation zones. They are also ideal for standard cold rooms and clean room applications. Their high impact resistance and ease of cleaning ensure full compliance with international sanitary guidelines. Surface finishes can be customized in flat, ribbed, or micro-ribbed profiles. This matches both your aesthetic preferences and structural load-bearing requirements.
Standard metal skins can degrade in harsh conditions like constant hot water washdowns or high-humidity environments. HELENG provides advanced composite alternatives using Fiberglass Reinforced Plastic (FRP). We also offer Continuous Fiber Reinforced Thermoplastics (CFRT). These advanced structural materials provide absolute resistance to chemical corrosion and extreme moisture ingress. They completely eliminate the risk of surface degradation in demanding processing plants or slaughterhouses.
To ensure a complete and continuous thermal envelope, our components are engineered for specific facility applications:
Wall Panels: Feature precision-engineered jointing systems like cam-locks or deep tongue-and-groove patterns. This ensures a completely airtight seal between adjacent spans.
Roof Panels: Designed with prominent external ribbing to handle high load-bearing demands. They easily withstand wind uplift and heavy snow loads in large industrial structures.
Floor Panels: Engineered with high-density polyurethane cores to reliably support heavy machinery. They safely withstand commercial forklift traffic and heavy pallet racks without settling.
Modern industrial facilities demand materials that deliver exceptional insulation while strictly meeting global safety regulations. HELENG’s high-performance structural elements are engineered to satisfy strict international standards. This ensures regulatory compliance for projects in Europe, North America, and high-spec industrial zones worldwide. Through precise chemical formulation and advanced foaming processes, we successfully maximize both thermal resistance and environmental sustainability.
We have transitioned our primary production line to utilize modern, environmentally responsible pentane blowing agents. Unlike outdated HCFC-141b agents, our rigid foam core is completely CFC-free. It yields a Global Warming Potential (GWP) of just 11 and zero Ozone Depletion Potential (ODP). This eco-friendly formulation allows developers to meet green building certifications without sacrificing insulation performance.
Fire safety remains a critical consideration in modern industrial building design. We precisely formulate our products with high-quality flame retardants. They achieve B1 (difficult to ignite) or B2 (self-extinguishing) class fire-rated specifications. These certified safety characteristics help contain smoke and restrict flame spread. This fully satisfies rigorous local and international building safety codes.
The thermal efficiency of our polyurethane cores is driven by a high closed-cell ratio exceeding 95%. This microscopic structure forms an impermeable barrier against water vapor absorption and air migration. By effectively locking out moisture, our systems maintain their original design R-value over decades. This completely avoids the thermal degradation common in lower-quality insulated structures.
Due to their versatility and uncompromising thermal properties, our products excel across demanding industrial settings. We carefully tailor face materials, core densities, and joint mechanisms for specific regulatory standards. This matches the exact temperature workflows required by your specific sector.
In food processing plants and low-temperature blast freezers, thermal boundaries must endure extreme conditions. Our insulated enclosures are engineered to withstand severe thermal shock and aggressive washdowns. We utilize food-safe stainless steel skins and non-toxic sealants. This maintains strict hygiene standards while containing temperatures down to -45°C securely.
Structural stability is paramount in high-capacity cold chain logistics centers and commercial supermarkets. We supply large-span structural components designed with exceptional wind-load resistance. Integrated cam-lock jointing systems allow for the rapid installation of massive warehouse envelopes. This creates a secure, airtight thermal seal that substantially reduces loads on central refrigeration machinery.
Research laboratories and biopharmaceutical facilities consistently require flawless environmental control. We provide customized cleanroom enclosures featuring ultra-smooth, flush joints to minimize dust accumulation. These protective surfaces strongly resist aggressive chemical disinfectants. They reliably help facilities maintain exact temperature and humidity tolerances for highly sensitive compounds.
Choosing the correct core thickness is essential for balancing capital expenditure with long-term energy savings. Insufficient insulation naturally leads to excessive compressor run times and unwanted ice build-up. Conversely, over-specifying unnecessarily inflates initial structural construction costs. Use the straightforward reference table below to identify the optimal thickness based on your design target temperatures.
| Panel Thickness | Recommended Temperature Range | Primary Cold Storage Application Type |
|---|---|---|
| 50mm / 75mm | +15°C to 0°C | Fresh preservation, processing rooms, ante-rooms, and commercial chillers. |
| 100mm / 120mm | 0°C to -18°C | Medium-temperature cold storage, frozen food storage, and logistics hubs. |
| 150mm / 200mm | -18°C to -45°C | Low-temperature freezers, deep-freeze storage, and rapid blast freezers. |
