Stainless steel insulated water tank uses a three-layer structure of "stainless steel inner tank + polyurethane foam insulation + stainless steel outer shell", perfectly combining the hygiene of stainless steel tanks with the insulation of insulating materials.

【Three-Layer Structure】Inner tank: SUS304/316L stainless steel, electrolytic polished inner wall (Ra≤0.4μm), meets sanitary requirements; Insulation layer: high-density closed-cell polyurethane foam (density 45kg/m³), thermal conductivity 0.022W/(m·K), thickness 50-150mm optional; Outer shell: 0.5mm SUS304 stainless steel plate, brushed surface.

【Insulation Performance】At 20°C ambient temperature, 100°C hot water in tank drops no more than 5°C after 24 hours; 4°C cold water rises no more than 3°C after 24 hours.

【Specifications】Capacity: 50L to 50m³; Working temperature (medium): -10°C to +150°C; Working pressure: atmospheric to 0.4MPa; Connections: sanitary quick-connect fittings (SMS/RJT standard).
