Engineering PSAoxygen generator
Sumitomo Seika offers highly reliable PSA oxygen generators based on our extensive knowledge and technical capabilities to create the high-quality products that only a chemical manufacturer can, which we have cultivated in the manufacturing of various chemical and synthetic products. PSA oxygen generators provide a stable supply of oxygen at a lower cost than liquid oxygen.
What is a PSA oxygen generator?
Pressure swing adsorption (PSA) oxygen generators are the equipment that produce oxygen at 90% to 93% purity using adsorbents to remove nitrogen gas from the air. The process is also known as pressure vacuum swing adsorption (PVSA), vacuum pressure swing adsorption (VPSA), and vacuum swing adsorption (VSA). Taking advantage of the fact that the adsorption quantity of the adsorbent (synthetic zeolite) under pressure is greater for nitrogen than oxygen, these generators remove nitrogen in the air through adsorption under pressure to efficiently produce high-purity oxygen.
Because they can provide a stable supply of oxygen at a lower cost than liquid oxygen, they have been adopted at facilities that use large amounts of oxygen.

Sumitomo Seika Strengths1 Solid Track Record
More than 100 projects completed outside of Japan, primarily in Taiwan and Southeast Asia
Sumitomo Seika products have been installed not only in Japan but in South Korea, Taiwan, Europe, Southeast Asia, Russia, and other areas around the world.
Our local partners, who are familiar with the circumstances in each region, provide support for installation.
Number of overseas deliveries and destinations (cumulative)
From compact to large-scale: Our extensive track record includes various applications
We have a track record of deliveries to customers using our generators in various applications, including electric furnaces, non-ferrous metal smelting, glass melting, and melting furnaces.
For example, up to now we’ve had customers switch to Sumitomo Seika generators from others they had been using, and other customers who had been using liquid oxygen switched over to our PSA generators for their cost performance. We have also had customers who had been using air for oxidation and combustion install our PSA generators and see improved production efficiency by using oxygen enriched air.
Not only do we deliver directly to electric furnace and non-ferrous metal smelting users but we can also deliver through our local partners, such as gas suppliers that supply oxygen gas, companies that carry various machinery and equipment, and engineering companies in charge of plant construction.

Sumitomo Seika Strengths4 Reliable Support
On-site or remote for everything from installation to maintenance
Our PSA oxygen generators are fully automatic and are started and stopped with just the touch of a button. The status of operation can also be checked via the intuitive touch panel. In addition, we have supervisors dedicated to PSA oxygen generators to provide support for everything from installation to maintenance. These supervisors can provide advice at the work site or, if cameras are installed, can provide remote support. Even first-time users can use our generators easily and with peace of mind.
