What material is used for the shell of a closed-circuit cooling tower?
So, how exactly should we choose the material for the shell of a closed-circuit cooling tower? From a professional standpoint, we recommend three types of shell materials.
So, how exactly should we choose the material for the shell of a closed-circuit cooling tower? From a professional standpoint, we recommend three types of shell materials.
First: Aluminum-zinc coated sheet metal.
The surface of aluminum-zinc coated sheets exhibits a distinctive smooth, flat, and lustrous appearance. Thanks to its unique coating structure, these sheets offer excellent corrosion resistance. Moreover, they boast outstanding heat resistance and anti-oxidation properties, with a typical service life of up to 25 years.

Second: Magnesium-aluminum-zinc coated steel sheet.
Magnesium-aluminum-zinc coated steel sheet is a new type of steel plate. It boasts exceptional corrosion resistance and is an internationally recognized, environmentally friendly product.

Third: 304 stainless steel sheet.
The 304 stainless steel plate is characterized by its relatively high nickel (Ni) and chromium (Cr) content, which enables it to adapt well to external environments and makes it highly resistant to rust and corrosion.

You might be wondering: Which material is best suited for the casing of a closed-circuit cooling tower? The answer depends on factors such as your cooling water flow rate, inlet and outlet water temperatures, local wet-bulb temperature, and your product’s specific process requirements.
