Galvanized insulated water tank is an economical insulated water storage product developed for cold northern regions, adding polyurethane foam insulation layer (50-150mm) on the outer wall of standard galvanized steel panel tank, covered with color-coated steel plate, effectively preventing freezing in cold regions.

【Insulation Structure Design】Inner tank: hot-dip galvanized steel (≥275g/m²) + food-grade inner coating; Insulation layer: high-density closed-cell polyurethane foam (density 40-45kg/m³, thermal conductivity ≤0.025W/m·K); Outer panel: color-coated steel (0.5mm); All pipe interfaces insulated to eliminate thermal bridges; Bottom drain insulation pin for easy winter drainage.

【Energy-saving Insulation Effect】At -20°C outdoor temperature: 50mm insulation maintains water temperature above 0°C for about 36 hours; 100mm insulation maintains above 0°C for about 72 hours.

【Applications】Northern outdoor rooftop water tanks; Rural safe drinking water projects; Construction site temporary water supply (winter construction); Industrial outdoor water supply facilities.

【Specifications】Capacity: 1-500m³; Insulation thickness: 50/75/100/150mm; Working temperature (ambient): -30°C to +50°C; Service life: 20-30 years.
