Cold Storage Panels from Shanghai Heleng Refrigeration deliver industry-leading thermal insulation. They ensure structural durability and energy efficiency for temperature-controlled facilities. As an established manufacturer, we leverage the industrial resources of Luohe Tian Shun Cold Chain Group. We produce high-performance panels that protect cold chain assets worldwide. Our specialized products utilize proprietary ThermoCore™ high-density insulation. They also feature the advanced Tian Shun Double-Tongue Joinery system to minimize thermal bridging.
Rather than simply supplying components, HELENG provides a comprehensive approach to cold room design and assembly. Our intelligent manufacturing base uses high-precision continuous production lines. This guarantees absolute uniformity in density and structural performance. These advanced fabrication capabilities ensure every insulated panel meets strict international standards. Consequently, our clients significantly reduce operational energy costs while maintaining tight temperature tolerances.
Our solutions optimize energy consumption by maximizing thermal R-values to protect against temperature fluctuations. Exceptional airtightness prevents vapor ingress, satisfying strict hygienic requirements. We offer standardized material options that meet FDA, USDA, and GMP compliance for cleanroom installations.
Choosing the correct core insulation material is essential for balancing thermal performance, budget constraints, and fire-safety requirements. At HELENG, we specialize in manufacturing both Polyurethane (PUR) and Polyisocyanurate (PIR) core formulations inside our sandwich panels. Both options utilize our ThermoCore™ high-pressure foaming technology to eliminate voids. This guarantees a uniform cellular structure across the entire panel length.
While PUR provides exceptional thermal efficiency, it remains highly cost-effective for standard storage configurations. Conversely, PIR offers an advanced hybrid formulation designed for maximum safety. These PIR panels exhibit superior self-extinguishing and flame-retardant properties. They achieve an impressive B1 fire-resistance rating that complies with rigorous industrial building codes. The table below details the technical differences to guide your selection process:
| Technical Parameter | PUR Cold Storage Panels | PIR Cold Storage Panels |
|---|---|---|
| Core Density | 40 - 42 kg/m³ | 42 - 45 kg/m³ |
| Thermal Conductivity | ≤ 0.022 W/(m·K) | ≤ 0.019 W/(m·K) |
| Operating Temperature Range | -50°C to +80°C | -150°C to +120°C |
| Fire Safety Rating | B2 Grade (Flame Retardant) | B1 Grade (Self-Extinguishing) |
| Best Suited Applications | Standard walk-in coolers, medium-temp cold rooms | Large-scale logistics, food processing, biopharma |
An insulated envelope is only as strong as its joints. To address different project scales and mechanical demands, HELENG designs two primary connection mechanisms. These secure our insulated panels and eliminate thermal bridging. Our structural joint options guarantee a completely sealed, airtight barrier. This prevents moisture infiltration and ice formation within the joints.
For modular walk-in coolers, specialized laboratories, and medium cold storage facilities, our cam-lock polyurethane panels offer a highly convenient joint option. These panels feature integrated eccentric locking fasteners embedded within the high-density foam during manufacturing. This allows onsite installers to tightly pull panels together with a simple hex key. The result is a perfectly flush, airtight connection. Cam-lock systems are ideal for projects requiring fast assembly, future expansions, or complete relocation.
For high-ceiling logistics warehouses, large-scale food processing facilities, and distribution hubs, continuous joint panels are the preferred standard. They utilize our proprietary Tian Shun Double-Tongue Joinery. This advanced profile creates a labyrinth seal at each joint, completely blocking vapor transmission and cold air escape. Installed without internal locks, these continuous panels support extended runs. They are structurally robust enough for heavy wind loads and high-rack integrations.
Selecting the correct cold room panel thickness is a critical engineering decision. It directly impacts operational power consumption, compressor sizing, and long-term equipment lifespan. Inadequate thickness leads to continuous heat gain, forcing refrigeration units to run longer. This increases energy bills and accelerates wear. Proper mapping ensures optimal insulation resistance (R-value) is maintained. This avoids surface condensation, joint icing, and structural degradation.
To assist project managers, structural designers, and refrigeration engineers, we provide a technical mapping table. It demonstrates how thickness levels correspond to target operating temperatures and estimated R-values using our advanced ThermoCore™ insulation foam.
| Application Type | Target Operating Temperature | Recommended Thickness | Core Material | Estimated R-Value (m²·K/W) |
|---|---|---|---|---|
| Processing Areas & Anterooms | +10°C to +15°C | 50mm / 75mm | PUR / PIR | 2.27 - 3.41 |
| Chilled Storage & Fresh Rooms (Most Common) | 0°C to +5°C | 100mm | PUR / PIR | 4.54 |
| Low-Temperature Walk-In Freezers | -18°C to -25°C | 120mm / 150mm | PUR / PIR | 5.45 - 6.81 |
| Deep Freeze & Blast Freezing | -35°C to -40°C | 200mm | PIR | 9.09 |
The external metal skin of an insulated panel must withstand demanding environmental conditions. These include high humidity, low-temperature cycles, and intense sanitization protocols. HELENG offers a variety of premium metal facings and specialized coatings. Sourced from top-tier suppliers like Baosteel, these materials match your facility's operational demands and regulatory compliance standards.
Our SUS304 Stainless Steel Panels are specifically designed for high-corrosion, wet, and saline environments.

What is the difference between PIR and PUR insulation cores in cold storage panels?
PUR (Polyurethane) provides excellent thermal efficiency and is highly cost-effective for standard cold rooms. PIR (Polyisocyanurate) is an advanced hybrid formulation that offers superior fire resistance (class B1). It also delivers up to 10% higher thermal performance, making it our preferred choice for large-scale logistics and highly regulated environments.
How do I choose the right thickness for my cold storage panels?
Panel thickness depends on your required internal operating temperature. We generally recommend using 100mm panels for medium-temperature chilled storage (0°C to 10°C). For standard freezers (-18°C to -25°C), 150mm panels are ideal. For deep-freeze or blast freezing applications (-30°C to -40°C), we utilize robust 200mm panels to prevent thermal bridging.
Are HELENG cold storage panels compliant with food safety regulations?
Yes, our panels are engineered to meet strict FDA, USDA, and GMP cleanroom standards. For food processing and pharmaceutical facilities, we offer specialized SUS304 stainless steel and antimicrobial-coated PPGI panels.
