Our engineering experts are on hand to explore whether a modularized or customized ASU would be a better fit for your volume and security of supply needs.
On-site ASUs for N2, O2 and Ar
Trust in Our Experience - and Enjoy the Security of On-site Supplies
As one of the world's largest and most experienced air separation unit (ASU) engineers, we are uniquely positioned to advise on the build and process technologies best suited to your volume and availability needs.
Scaling from Modularized Builds to World-class Plants
If you need a steady, reliable, ultra-high stream of oxygen (O2), nitrogen (N2) and/or argon (Ar), it might make sense to have your own air separation unit (ASU) built on site instead of relying on bulk or pipeline deliveries. These air separation plants then generate the gases you need - on demand.
Having already engineered and delivered more than 1,000 ASUs in 90-plus countries, we are one of the largest and most experienced suppliers in the world. Our execution expertise covers the full technology, engineering, procurement and construction (T-EPC) lifecycle. Currently, our ASU process innovations are protected by over 356 patents. We also operate over 550 of our own ASUs, channeling this experience into the ongoing optimization of our process technologies.
Reflecting the highly individual nature of needs in this area, our plants scale from containerized and modularized ASUs to custom-engineered turnkey plants, producing anything from a few hundred tons per day (tpd) to 5,500 tpd. Purity levels also range from low to ultra-high to meet application-specific requirements.
SPECTRA® for On-site Generation of N2 and O2
Our series of SPECTRA® on-site generators gives you a cost-effective and reliable path toward ultra-pure, liquid nitrogen with impurity levels of less than 1 part per billion (ppb) and ultra-pure, liquid oxygen with less than 10 ppb impurities, with capacities scaling from 7,000 to 70,000 Nm3 per hour.
