1) Good sealing: Isolate air storage to prevent harmful substances and microorganisms in airborne dust from entering the tank, ensuring that the materials in the tank are not polluted by the outside world.

2) Good corrosion resistance: Made of high-quality stainless steel, some corrosive elements in the air have no effect on it. Under normal circumstances, its service life can reach decades or even hundreds of years.

3) Good cleanliness: According to the cleanliness required by the material, the inner surface of the tank can be polished to the required accuracy to meet the cleanliness requirements.

4) Easy to use: The drain valve at the bottom of the tank can remove precipitated debris and improve the use efficiency of the stainless steel chemical storage tanks. Simple equipment can be used to remove scale once every three years, thereby reducing cleaning costs and completely avoiding human bacterial and viral contamination. Save water.

5) Flexible structure:Vertical or horizontal storage tanks of various specifications and sizes can be configured according to the actual conditions on site, and various nozzles, various heating or cooling jackets, coils, insulation, agitators, etc. can be flexibly selected according to usage requirements. structure.
