Pressure Vessels Compressed Air and Nitrogen

Why is a pressure vessel needed for compressed air or nitrogen production?

In every compressed air or nitrogen system, there are fluctuations in usage. Sometimes the demand exceeds the production capacity, and sometimes it’s lower. A pressure vessel acts as a buffer to absorb these peaks and troughs.

Advantages of a pressure vessel:

• Temporary higher consumption than production:

The pressure vessel temporarily holds extra volume when consumption exceeds production capacity. The pressure in the vessel drops without immediately affecting the system’s performance.

• Storage during overcapacity:

When consumption is lower than production, the pressure in the pressure vessel increases. Once a preset maximum pressure is reached, the compressor or nitrogen generator automatically shuts off via a pressure switch. When the pressure drops below a certain threshold, the system switches back on. This saves energy and reduces wear on equipment.

Pressure vessels prevent unnecessary venting of air or nitrogen

Without a pressure vessel, excess compressed air or nitrogen would need to be continuously vented to keep the system balanced. This not only wastes energy but also shortens equipment life and harms the environment.

Even in systems with variable speed compressors, a pressure vessel is essential to prevent pressure fluctuations and ensure consistent quality and supply.
