There are many benefits of cryogenic based oxygen nitrogen plants. We will discuss them one by one. Firstly, you must understand cryogenic distillation is the best methodology for air separation. Industries prefer to use only the cryogenic extraction.
There are other technologies also such as pressure swing adsorption and membrane. These techniques are good but do not match the effectiveness and quality of cryogenic distillation. Only cryogenic process can produce oxygen and nitrogen on large scale with high purity.
PSA methodology can fulfill the requirements of small and micro businesses. The PSA oxygen generator plants can generate oxygen in small volume with low purity. PSA systems operate on adsorption process that uses adsorbing materials like Zeolite adsorbent. In this process, Zeolite molecular sieves adsorb more than the others. Oxygen passes through while nitrogen is adsorbed.
Amongst the benefits, you cannot ignore the efficiency and reliability of delivering uninterrupted supply of oxygen, nitrogen and with some modifications argon via fractional distillation. Industries and hospitals prefer cryogenic production because you can store cryogenic liquids at low pressure.

Many customers wonder why cryogenic plants are pricier than the PSA generator plants. They get confused since both produce oxygen but their prices are so different. To clear their doubts, they use differently technologies. PSA uses simple technologies with simple and low priced components.
On the other hand, cryogenic air separation unit uses cutting-edge technology with many elaborate processes using high quality components and parts. The process can generate only oxygen or nitrogen in both liquid and gaseous form. This is the reason why air separation plants costlier than PSA oxygen plant.
