Energy saving: good compact polyurethane foam insulation layer to ensure good thermal insulation of the water tank. Box structure, maintenance hole by equally high frequency resistance welding, ensure the body completely tight, effectively prevent the destruction of external and internal rain water vapor on the insulation layer, reduce the heat loss. The heat loss is reduced by the design of the heat proof bridge deck, the top and the bottom. An anti convective device with a patent on the overflow hole has effectively prevented the convection heat transfer between the air on the water tank and the outside air, and reduced the heat loss. After testing by authoritative professional institutions, the temperature drop of <3 is <3 degrees.

耐用性：深入研究不锈钢腐蚀机理，长期实践解决腐蚀问题。采用优质不锈钢板整板卷筒压筋，环形对接，箱顶和箱底采用大型液压机一次成型，确实保证箱体强度。采用高频滚焊机焊接，焊缝质量可靠，同时消除了焊接应力，防腐性能大幅增强。

Durability: in-depth study of stainless steel corrosion mechanism, long-term practice to solve the corrosion problem. The use of high-quality stainless steel plate plate embossing drum, box top and bottom ring butt, forming a large hydraulic machine, ensure body strength. With high frequency welding machine, the weld quality is reliable, the welding stress is eliminated and the anticorrosion performance is greatly enhanced.

美观性：采用大型专用设备，制定严密工艺，采用必要工装，标准制作，接管横平竖直，产品圆润有形。

Beauty: the use of large special equipment, the formulation of strict process, the use of necessary tooling, standard production, takeover horizontal vertical, product round and tangible.
