Líneas de Paneles para Cámaras Frigoríficas en la Construcción de Almacenamiento en Frío Industrial
Las cámaras frigoríficas se construyen con paneles sándwich continuos — núcleo de espuma de PU entre revestimientos de acero. Suministramos la línea de producción continua de paneles para cámaras frigoríficas (10 – 40 paneles por hora), los sistemas de espuma proyectada para el relleno in situ y el suministro de materia prima de PU. Los paneles van desde 50mm de espesor (cámaras de refrigeración) hasta 200mm (cámaras congeladoras industriales).
In one line
Capacidad a escala industrial: líneas de producción continua de hasta 40 paneles/hora con paquete completo de maquinaria (perfiladoras, estaciones de encolado, prensa de doble banda).
Real Pains We Hear from Buyers — and What We Ship to Solve Each One
Four pains every cold-room-panel factory founder brings us. Our line ships with the fix for each.
Panels fail EN 14509 bond-strength test — steel skin separates from PU core in pull-off test
EN 14509 bond strength ≥0.10 MPa requires steel-skin chemical pre-treatment + PU adhesion calibration + press temp/time control. Our line ships with: PPGI steel skin specifically primed for PU bonding, calibrated cyclopentane PU adhesion package, hot-press 35–45°C control. Field-tested bond strength: 0.12–0.18 MPa, well above minimum.
Continuous press throughput 4 m/min on paper but real-world output is only 2.5 m/min — utilization gap eats my margin
Press throughput drops below spec when foam rise time + line speed + cure profile don't align. Our engineering tunes PU formulation rise time (90–120s) to match your target line speed (3–5 m/min). Pre-shipment FAT runs your actual panel spec on our test line to confirm throughput before crating. Field utilization typically 85–95% of rated speed.
Discontinuous vs continuous press — buyer offers different deal sizes, I don't know which line to invest in
Below 800K m²/year → discontinuous (lower capex USD 800K–1.5M, flexible thickness/length). Above 800K m²/year → continuous (USD 2.5M–5M capex, faster throughput, narrower thickness range). Mixed deals: most factories start with discontinuous, upgrade to continuous after 24 months when commercial orders stabilize.
Fire reaction EN B-s2,d0 needed for EU cold-room tender — my current panels only achieve E-class
Fire reaction class is driven by PU formulation chemistry (flame retardant package) + steel skin thickness + panel joint design. Our PU formulation includes the FR additive package certified to EN B-s2,d0 (limited combustibility). We supply the test certificate pack so EU tender submission has the EN 14509 + fire reaction class B documented.
