Cold Storage Insulation
High-density closed-cell PU foam for walk-in freezers, cold chain warehouses, and food processing facilities operating at -25°C to -40°C.
Overview
Cold storage demands continuous thermal envelope performance at extreme temperature differentials. Closed-cell PU foam at 40-45 kg/m³ delivers R-6.5+ per inch with zero moisture permeance. Pioneer JYYJ-H600PK with adjustable 1:1~1:2 mixing ratio handles custom high-density formulations required for food-grade cold chain (-25°C operational) and blast freezing (-40°C).
Recommended JYYJ Machines
JYYJ-H600PK
$5,000Flagship hydraulic spray machine with 10-inch PLC touchscreen and adjustable mixing ratio (1:1~1:2). 2-10 kg/min at 36 MPa for polyurea, high-density foam, and precision-critical applications. Recipe memory and data logging for project documentation. Adjustable ratio handles temperature-driven viscosity shifts and custom material formulations — unique in the JYYJ line.
JYYJ-H600
$3,250Entry-level hydraulic spray machine — the gateway to professional-grade pressure. 2-12 kg/min at 36 MPa with 6-18 MPa hydraulic system pressure. Compatible with both polyurethane foam and polyurea coatings. Air-cooling system protects motor and pump for sustained heavy-duty operation.
JYYJ-H800
$5,200Maximum-throughput hydraulic spray machine with simple button controls. 2-14 kg/min at 36 MPa with 38 kW heating — the highest heating power in the JYYJ line for sub-zero environments. Built for large industrial projects where output volume matters more than touchscreen sophistication.
Recommended Materials
Browse Polyurethane Foam (A + B) →- ● Closed-cell rigid PU foam (40-45 kg/m³)
- ● Vapor-barrier primer
- ● Food-grade topcoat (optional)
Why This Setup Works
R-value 6.5+ per inch maintains -25°C to -40°C interior with minimal envelope thickness
Zero moisture permeance — no interstitial condensation, no insulation degradation
Seamless application around irregular geometry (piping, conduit penetrations)
Long-term energy savings 35-50% vs fiberglass/XPS alternatives
Technical Considerations
- Target density: 40-45 kg/m³ for -25°C, 45-50 kg/m³ for -40°C
- Recommended thickness: 150-200mm based on delta-T and R-value target
- Substrate temperature must be stable during application
- Fire rating: check local building code for food-grade topcoat requirement
