Ivar Air Separation Plant & Infrastructure

Industrial Gas Manufacturing & Technical Capabilities

Explore the advanced technical infrastructure of Ivar Industrial Gas Limited—featuring our 24/7 cryogenic air separation plant, high-pressure automated filling station, analytical quality lab, and in-house cylinder testing rig.

OUR CORE FACILITIES

Integrated Gas Production & Quality Assets

Every facility at our industrial complex is engineered to meet strict international standards for purity, pressure safety, and operational reliability.

FACILITY 01CRYOGENIC AIR SEPARATION

Cryogenic Air Separation Unit (ASU) Column

Continuous sub-zero fractional distillation at -196°C

Our state-of-the-art cryogenic Air Separation Unit operates continuously to compress, purify, and fractionate atmospheric air into pure oxygen and nitrogen. Designed for high volume efficiency and extreme purity control, the facility utilizes multi-stage molecular sieve pre-purification to eliminate ambient moisture, carbon dioxide, and trace hydrocarbons prior to liquefaction.

Technical Specifications & Operational Features:

Operating Temperature:-196°C (-320°F) Sub-zero cryogenic column
Fractionation Method:Multi-stage cryogenic fractional distillation
Pre-Purification System:Dual-bed molecular sieve adsorption (H₂O / CO₂ removal)
Output Capabilities:High-pressure gaseous pipeline & liquid cryogenic storage
Automation Level:24/7 Distributed Control System (DCS) with continuous telemetry

FACILITY 02HIGH-PRESSURE BOTTLING

Automated High-Pressure Filling Manifold

Precision multi-bank cylinder charging rated up to 300 BAR

Designed for heavy-duty industrial and medical gas filling, our automated manifold stations ensure consistent density, precise pressure regulation, and contamination-free charging. Every cylinder batch undergoes an automated deep-vacuum evacuation sequence before filling to flush out any residual atmospheric gases.

Technical Specifications & Operational Features:

Pressure Ratings:150 BAR, 200 BAR, and 300 BAR (4,350 PSI) charging banks
Pre-Fill Evacuation:High-vacuum purge cycle (< 1 mbar absolute vacuum)
Manifold Piping:Electro-polished 316L stainless steel to prevent particulate contamination
Cylinder Configurations:40L/50L individual cylinders & 12-cylinder Manifold Packs (MCPs)
Safety Controls:Automatic over-pressure relief valves & thermal emergency shutoffs

HIGH-PRESSURE BOTTLING
FACILITY 03QUALITY ASSURANCE

Analytical Quality Control Laboratory

Batch verification with trace gas chromatography & dew-point sensors

Quality is verified at every stage of production. Our on-site analytical testing lab is staffed by experienced chemical technicians and equipped with precision analytical instruments capable of identifying impurities down to parts-per-million (ppm) and parts-per-billion (ppb) thresholds.

Technical Specifications & Operational Features:

Analytical Instruments:Gas Chromatography (GC), Electrochemical O₂ Analyzers
Moisture Detection:Electrolytic & Quartz Crystal Microbalance dew-point meters
Medical Compliance:Pharmacopoeia (USP / Ph. Eur.) medical oxygen verification
Certification:Serialized Certificate of Analysis (CoA) issued per filling batch
Quality Audit Trail:Full digital batch traceability linked to cylinder serial numbers
Analytical Quality Control Gas Laboratory
QUALITY ASSURANCE
FACILITY 04CYLINDER INTEGRITY & SAFETY

Cylinder Hydrostatic Re-Qualification Rig

In-house hydraulic wall testing, valve servicing & thermal drying

Safety is paramount when handling high-pressure compressed gases. Our facility features an in-house cylinder testing and maintenance shop certified to perform periodic hydrostatic water-jacket pressure testing, internal borescope inspections, valve overhauls, and thermal internal drying.

Technical Specifications & Operational Features:

Testing Pressure:Hydrostatic water-jacket test up to 450 BAR (1.5x working pressure)
Internal Inspection:High-intensity fiber-optic borescope wall integrity checks
Internal Moisture Drying:Hot dry-nitrogen purge oven (120°C) for complete moisture extraction
Valving & Refurbishment:Ultrasonic neck thread cleaning, torque-calibrated valve installation
Tagging & Stamping:Permanent tare weight stamping, re-test date tagging & color coding
