Knowledge Base

Q

Fiberglass nitrogen sealed water tanks have been widely used in various fields due to their advantages of corrosion resistance and good sealing. Here are some specific cases: -Electronics industry: In the manufacturing process of electronic chips, ultra pure water is required. To prevent the water quality from being affected by the contact between ultra pure water and oxygen and carbon dioxide in the air, some companies have adopted fiberglass ultra pure water nitrogen sealed water tanks. The main body of the water tank adopts

Q

A nitrogen sealed water tank is a water storage device with a nitrogen sealing device, which maintains a slight positive pressure inside the tank by filling it with nitrogen gas to isolate air from entering. It can prevent oxidation and pollution caused by contact between water and oxygen, ensuring stable water quality. Widely used in industries with high water quality requirements such as food, medicine, and chemical engineering, it has a compact structure and is equipped with a pressure control system that can automatically adjust the nitrogen gas volume to ensure sealing effectiveness.
