Nitrogen generators are systems designed to produce nitrogen gas on-site using either membrane separation or pressure swing adsorption (PSA) technology. These systems offer a cost-effective, reliable, and continuous nitrogen supply across industries such as food & beverage, pharmaceuticals, oil & gas, electronics, and chemicals—eliminating the need for bottled or bulk nitrogen deliveries.

The global Nitrogen Generators market was valued at USD 9.5 billion in 2023 and growing at a CAGR of 5.7% from 2024 to 2033. The market is expected to reach USD 16.54 billion by 2033.
