What is cryogenic air separation?
Cryogenic air separation is a process that cools air to extremely low temperatures to liquefy its components, allowing for the separation of oxygen, nitrogen, argon, and rare gases through distillation.
What purity levels of oxygen and nitrogen can be achieved with these generators?
UIG’s non-cryogenic generators typically produce oxygen with purity up to 93% and nitrogen with purity levels up to 99.999%, depending on the technology and application requirements.
What are the benefits of using onsite oxygen and nitrogen generators?
Onsite generation reduces dependency on bulk deliveries, lowers transportation and storage costs, improves supply reliability, and allows for flexible gas supply that matches your production needs.
What industries rely on cryogenic air separation plants?
Industries such as steel, energy, glass, chemicals, mining, and metals depend on cryogenic air separation for a steady and high-purity gas supply.
What are the benefits of using onsite oxygen and nitrogen generators?
Onsite generation reduces dependency on bulk deliveries, lowers transportation and storage costs, improves supply reliability, and allows for flexible gas supply that matches your production needs.
How does onsite gas generation impact safety?
Onsite generation minimizes the risks associated with transporting and storing large volumes of cryogenic liquids, improving workplace safety and reducing handling hazards.
What is the typical footprint of a non-cryogenic oxygen or nitrogen generator?
Non-cryogenic generators are compact compared to cryogenic plants, making them suitable for facilities with limited space or where a smaller scale gas supply is needed.
Can non-cryogenic generators be scaled up as my gas demand increases?
Yes, these systems are modular and can be expanded or adjusted to meet growing or fluctuating gas demands, providing flexibility for changing operational needs.
What makes UIG different from other industrial gas suppliers?
UIG offers flexible supply options, from turnkey plants to DIY solutions, ensuring that you get a gas supply model that aligns with your business needs – not the supplier’s bottom line.
UIG, a wholly owned subsidiary of Nucor Corporation, designs, builds, and operates air separation plants across North America.
What services does UIG provide beyond non-cryogenic air separation?
UIG offers a full range of industrial gas services including cryogenic air separation, bulk liquid gas supply, gas consulting, pipeline gas delivery, maintenance, and support.
