Cold Storage Envelope Spray Solution
A mobile hydraulic PU spray package with heated hose delivery for site-applied cold-storage insulation and access-specific layouts.
Seamless Thermal Envelopes for High-Bay Cold Storage Facilities
A mobile hydraulic PU spray package with heated hose delivery for site-applied cold-storage insulation and access-specific layouts.
Equipment and process scope
Hydraulic proportioning skid, heated hose, spray gun, drum feed and controls; vehicle, generator, access platforms, substrate preparation and site services are configuration interfaces.
Validation and production planning
Vertical lift, hose length and gun pressure require a complete loss calculation; hydraulic drive does not eliminate hydrostatic or friction losses. Coverage requires thickness, density, material use, overspray and actual spraying duty. A 2,550 m²/day area at 150 mm thickness is 382.5 m³/day before overspray; reconcile this with 14 kg/min maximum output and the supplied foam density. Foam fire classification and installation acceptance are separate from equipment delivery.

Substrate Cleaning & Moisture-Barrier Priming
Supplied process reference: Concrete masonry walls are dry-vacuumed, and a penetrating polyurethane primer is spray-applied to achieve tensile adhesion > 0.2 MPa.
Ground Hydraulic Pressurization & 60m Elevation
Supplied process reference: Truck-mounted hydraulic cylinders displace polyol and isocyanate at 17.5 MPa, pumping fluids up 60m heated umbilical lines without pressure loss.
Anti-Crystallization Thermal Inline Heating
Supplied process reference: Chemical streams pass through 18 kW primary heaters and heated copper-mesh lines, holding material temperatures at 50°C ± 1°C at the gun.

Core Advantages of Haifeng Envelope Spray Systems
Configured equipment functions and interfaces for the selected material and tooling.
60m Ground-to-Roof Pumping
Supplied configuration function: Non-pulsing hydraulic displacement delivers fluids up 60m elevations, removing dangerous chemical drums from high scaffolding. Project-dependent performance requires validation.
Total Thermal Bridge Elimination
Supplied configuration function: In-situ seamless expansion creates an unbroken 150 mm barrier, preventing joint condensation and ice buildup. Project-dependent performance requires validation.
2,500 m² Daily Productivity
Supplied configuration function: High continuous flow capacity allows crews to complete large multi-thousand-square-meter envelopes rapidly. Project-dependent performance requires validation.
Winter-Proof Inline Heaters
Supplied configuration function: Multi-stage 18 kW heaters prevent isocyanate crystallization, allowing cold-weather outdoor spraying down to 5°C. Project-dependent performance requires validation.
