Cold Storage PU Foam Insulation Solution
High-pressure in-situ polyurethane insulation systems for commercial cold rooms and deep-freeze facilities, delivering seamless hermetic barriers down to -40°C.
Seamless In-Situ Polyurethane Solutions for Cold Storage & Freezers
Extreme temperature differentials in commercial cold storage facilities (-20°C to -40°C) generate severe vapor drive forces that degrade conventional insulation. Prefabricated sandwich panel assemblies rely on joint gaskets and silicone seals that eventually shrink, crack, and leak under continuous thermal cycling, resulting in heavy frost accumulation, ice bridging, and soaring refrigeration power bills. Haifeng’s high-pressure in-situ spray and pour polyurethane solution applies a continuous, jointless insulation mantle directly onto cold room floors, walls, and ceilings. Solidifying in seconds with a closed-cell ratio exceeding 96%, the monolithic barrier permanently stops vapor infiltration and guarantees thermal conductivity down to λ ≤ 0.020 W/(m·K).
100% Frost-Free Monolithic Integrity
Eliminates mechanical joint gaps and thermal bypass channels around ceiling joists and wall intersections, permanently preventing ice build-up.
Severe Vapor Barrier Durability (λ ≤ 0.020)
A 96%+ closed-cell microcellular structure resists intense water vapor transmission, ensuring decades of uncompromised refrigeration performance without moisture logging.
Spraying equipment is configured with installation and inspection responsibilities agreed for the site.
Production Workflow for Cold Storage PU Foam Insulation Machine System
The workflow for Cold Storage PU Foam Insulation Machine System covers Substrate Cleaning, Thermal Conditioning, Monolithic Spraying, Polyurea Topcoat. Confirm the sequence and equipment interfaces against the selected material system and product design.
Substrate Drying & Primer Activation
Concrete or masonry walls are dried and swept; specialized moisture-barrier primers are rolled onto surfaces to promote high chemical bonding strength.
High-Pressure Precursor Thermal Regulation
High-output proportioner heaters and heated hoses maintain chemical precursors at 50°C–58°C, lowering fluid viscosity for complete impingement atomization.
Multi-Pass In-Situ Cold Room Spraying
Formulated chemicals are sprayed in successive 20–30mm passes; exothermic heat crosslinks the rigid core, creating an unbroken 100–200mm envelope across corners.
