Air Separation Plant (ASU) Supplier & Manufacturer in India

Cryogenic oxygen & nitrogen plants for cylinder filling.

Technology: Cryogenic distillationProducts: O₂, N₂ (gas & liquid)Scope: Turnkey design & commissioning
Air Separation Plant (ASU) — International Industrial Gases Ltd

Cryogenic air-separation units (ASU) that produce high-purity oxygen and nitrogen by compressing, cooling and distilling air — engineered for cylinder filling and bulk supply.

A cryogenic air-separation unit cools air to around −190 °C and distils it into its components — oxygen, nitrogen and argon — at high purity. IIGAS supplies turnkey ASUs for on-site oxygen and nitrogen production, gas and liquid output, cylinder filling and medical or industrial supply.

Plants are engineered for reliable, energy-efficient operation and built to ASME, CGA and EIGA standards, with full design, installation and commissioning.
