Complete turnkey acetylene plants — designed and built in-house
IIGAS supplies acetylene gas plants on a full turnkey basis: process design, fabrication, erection, installation, commissioning and operator training, backed by lifetime spares and service. Because we manufacture the plants and operate them ourselves to fill cylinders, every system is engineered from real production experience — not theory.
Our plants generate acetylene from calcium carbide, purify and dry it, compress it, and fill it into dissolved-acetylene (DA) cylinders charged with acetone or DMF over a porous mass — the safe medium for storing and transporting acetylene. We size each plant to your output, from compact installations to high-capacity industrial facilities.
What a turnkey IIGAS acetylene plant includes
- ✓Acetylene generators — low- and medium-pressure carbide-to-water and water-to-carbide designs
- ✓Gas purification and three-stage drying for high-purity acetylene
- ✓Acetylene compressors and high-pressure manifolds
- ✓DA cylinder filling systems with acetone/DMF charging and porous-mass handling
- ✓Flashback arrestors, flame arrestors and hydraulic back-pressure valves for decomposition safety
- ✓Carbide handling, sludge (carbide-lime) management and effluent systems
- ✓Instrumentation, control panels and complete safety interlocks
KIGL-DA acetylene gas plant models — 15 to 200 m³/hr
IIGAS acetylene gas plants are built around our fully automated carbide-to-water generator with twin hoppers and automatic screw feed — the generator switches hoppers automatically, so production is continuous and the plant needs only about 10 minutes of operator attention per hour. The stationary carbide-to-water design needs no gas holder, vents no acetylene to atmosphere, and reaches up to 99.8% plant efficiency.
| Model | Capacity | Cylinders / batch | Hopper capacity | Connected load |
|---|---|---|---|---|
| KIGL-DA-25 | 15–30 Nm³/hr | 40 | 250 kg | 12 kW |
| KIGL-DA-45 | 31–50 Nm³/hr | 60 | 400 kg | 15 kW |
| KIGL-DA-100 | 51–100 Nm³/hr | 120 | 500 kg | 24 kW |
| KIGL-DA-200 | 101–200 Nm³/hr | 180 | 900 kg | 38 kW |
All models run at a maximum operating pressure of 1.38 bar, accept 4–80 mm carbide (dust-carbide designs also available), start up in about 15 minutes, and are manufactured to IS 8471, ASME Section VIII, UL-408T, RAC-203 and NFPA 51A. Portable acetylene plants (B-1 and S-20 trolley-mounted units) are also available for field service.
Engineered to international safety standards
Acetylene demands uncompromising safety engineering. Our plants are built to NFPA 51A, CGA, EIGA, ASME and Indian Standards, and our team contributes to the Bureau of Indian Standards committees CHD 6 (Industrial Gases) and MED 16 (Gas Cylinders), so our plants are built to the standards those committees set.
Every plant is designed to contain and prevent acetylene decomposition — wet- and dry-type flashback arrestors, high-pressure reverse-flow check valves, automatic vent and safety valves, fail-safe automatic controls with visual and audible alarms, and uniflow valve-cum-flashback arrestors on every manifold limb — with porous-mass DA cylinders engineered to IS 8451 and related codes.
Trusted by steel plants, PSUs and gas companies worldwide
IIGAS acetylene plants and equipment run at some of the most demanding sites in India: Bharat Heavy Electricals Ltd (Bhopal, Hardwar, Trichy and Vellore), SAIL Rourkela Steel Plant (70 m³/hr plants feeding direct to pipeline), Visakhapatnam Steel Plant (3 × 25 m³/hr direct-to-pipeline plus a 270-cylinder distribution system), Tata Steel, Oil India Ltd, Cochin Shipyard, Balaji Amines and The Travancore Electro-Chemical (up to 200 m³/hr).
Beyond India, our plants and compressors operate in 20+ countries — Malaysia, Singapore, Indonesia, the Philippines, Thailand, Myanmar, Cambodia, Bangladesh, Sri Lanka, the UAE, Saudi Arabia, Bahrain, Oman, Egypt, Turkey, Iran, Mauritania, Brazil, Canada and the USA.
Exported and commissioned worldwide
Beyond acetylene, IIGAS builds air-separation plants, PSA oxygen plants and nitrous-oxide plants, and distributes the chemicals the industrial-gas industry depends on. Our plants are exported and commissioned worldwide, supported by our own engineers, spares and operator training.
