Enamel insulated water tank adds high-density polyurethane foam insulation layer (thickness 50-150mm) on the outer wall of the enamel steel panel tank, covered with 0.5-1.0mm color-coated steel plate, forming a complete three-layer composite structure of "enamel steel inner tank + polyurethane insulation middle layer + color-coated steel outer shell".

【Insulation Performance】Polyurethane foam thermal conductivity: 0.022-0.025W/(m·K); With 50mm insulation at -20°C, water temperature maintained above 0°C for 48 hours; With 100mm insulation, maintained above 0°C for over 72 hours; Summer heat insulation effectively prevents water evaporation and temperature rise.

【Outer Shell Structure】Color-coated steel plate (0.5-1.0mm), multiple color options (white, grey, blue); Hidden screw fixing for clean appearance; Integral polyurethane foam between outer shell and inner tank, no gaps, stable insulation effect.

【Specifications】Capacity: 2-500m³; Insulation thickness: 50/75/100/150mm (customized); Working temperature (ambient): -30°C to +50°C; Service life: 30-50 years.
