Introduction
Chile is a leading global seafood exporter; the demand for cold chain solutions-spanning products from salmon to king crab-continues to rise. Insulated panels are the core component of any efficient cold storage facility. Among the options available, 100mm PU (polyurethane) sandwich panels have become the most popular choice for seafood cold storage projects along the Chilean coast.
I. Matching Temperature Requirements with Panel Thickness
Seafood cold storage involves a wide range of temperature requirements: fresh fish require -1°C to 0°C; chilled processed products need 0°C to +5°C; frozen goods require -18°C or lower; and quick-frozen products may even require -25°C to -30°C.
Chile's cold chain sector is subject to dual regulation by the Ministry of Health's *Food Hygiene Regulations* and the National Fisheries Service (SERNAPESCA), while also having to meet international export standards.
For the most common category-chilled seafood storage (0°C to +5°C)-100mm PU panels offer the optimal balance of cost and performance. They are also suitable for -18°C freezing facilities. However, for deep-freeze facilities operating below -25°C, upgrading to panels 150mm or thicker is recommended.
II. Why Choose 100mm PU Panels?
Excellent Thermal Insulation-PU foam boasts a thermal conductivity as low as 0.022 W/m·K and a heat transfer coefficient below 0.25 W/m²·K, resulting in shorter compressor run times and lower electricity costs.
Inherent Moisture Resistance-The closed-cell structure prevents water absorption; when paired with galvanized steel or stainless steel facings, the panels effectively withstand the high-humidity, salt-laden coastal environment of Chile.
Lightweight and Seismic-Resistant-Given the frequency of earthquakes in Chile, the lightweight, modular structure of PU panels offers a natural seismic advantage.
Long Service Life-With an average lifespan of 15–20 years, the total lifecycle cost is far superior to alternatives like EPS. Taking a medium-sized cold storage facility in southern Chile as an example, upgrading from EPS to 100mm PU panels can reduce annual energy consumption by 15%–25%, with an investment payback period of just 2–4 years.
III. Installation Essentials
Ensure all joints are sealed with food-grade silicone to prevent moisture ingress; do not overlook the floor insulation layer; use specialized accessories for wall and ceiling corners to eliminate thermal bridges; for seafood processing areas subject to frequent washdowns, stainless steel or PVC-laminated panels are recommended.
Summary
🐟 Cold Storage (0°C to +5°C) → 100mm PU panels are the optimal choice
🧊 Freezer Storage (-18°C) → 100mm panels are sufficient
❄️ Deep Freeze Storage (below -25°C) → 150mm+ panels recommended
