PU Sandwich Panels For Cold Storage

Why choose PNS polyurethane sandwich panels to build cold storage rooms?

PNS polyurethane sandwich panels have become the preferred material for modern cold storage construction with their "insulation + structure + environmental protection" trinity. The following are its core advantages:

Ultra-low thermal conductivity: 0.018~0.023 W/(m·K), energy saving efficiency increased by 40%+

Closed-cell rate ≥95%: prevent water penetration, moisture and mildew

B1 fireproof certification: no droplets, low smoke density, to ensure storage safety

Modular construction: shorten construction period by 50%, support rapid production

Analysis of the core performance of PNS polyurethane sandwich panels (with industry comparison data)

1.Thermal insulation performance: better than traditional materials

The thermal conductivity of PNS pu sandwich panels is only 1/3 of that of EPS, and it has significant energy-saving advantages in low-temperature environments.

Structural strength and cost-effectiveness

(1) Compressive strength ≥ 150kPa: can bear heavy-duty shelves (e.g., a single-layer load-bearing capacity of a cold chain warehouse reaches 3 tons/m²)

(2) Lightweight design: unit weight 12-18kg/m², saving 30% of transportation and installation costs

(3) Lifespan of more than 25 years: metal panel + anti-corrosion coating, long maintenance-free period

PNS polyurethane sandwich panel application scenarios and successful cases

1. Food cold chain storage

Case: A multinational food company's 5000m³ freezer project

Using 15cm thick pu panels, annual electricity bill savings of $80,000

Temperature fluctuation ≤±0.5℃, HACCP certified

2. Pharmaceutical GSP/GMP cold storage

Solution: Stainless steel pu panel + intelligent temperature control system

Meet 2~8℃ constant temperature and humidity, FDA/EMA certified

Seamless surface, easy to clean, reduce the risk of cross contamination

3. Cold chain logistics and special scenarios

Refrigerated compartments: 12cm thick plate, temperature fluctuation during transportation ≤1℃

Agricultural pre-cooling warehouse: The shelf life of fruits and vegetables in tropical areas is extended by 3 times

New energy field: Customized anti-static plates for lithium battery storage

The whole process of PNS polyurethane sandwich panel construction

1. Design stage: BIM modeling optimizes the layout of cold storage and avoids the cold bridge effect

2. Installation stage: dry operation + lock splicing, shortening the construction period by 50%

3. Acceptance criteria: airtightness test (≤5% cold leakage rate) + infrared thermal imaging detection

Q: Can PNS polyurethane sandwich panels be used in -80℃ ultra-low temperature cold storage?

A: High-density core materials (≥60kg/m³) can be customized to support stable operation in -80℃ environment.

Q: How to choose metal panels?

A: Stainless steel plates are preferred in high humidity environments, and galvanized color steel plates can be used in conventional scenarios.
