Air Liquide in Thailand Industry


Our customisable solutions are geared toward improving process safety, maximising productivity and reducing the environmental footprint of our customers’ operations. We supply industrial and speciality gases in a wide array of volumes and purities, along with related application technologies and services.


The metals industry is constantly facing increasing challenges of reducing production costs while improving product quality and process productivity. Key players strive to continually reduce their environmental impact and optimise the use of critical resources (such as coke, ore, metal scrap and energy) through improved efficiency.

The industry requires oxygen, nitrogen and argon for a wide range of applications, ranging from oxy-combustion to surface protection and degasification with inert gases. We deliver competitive offers, from gas supply to comprehensive and tailor-made solutions.

  • Steel: for melting, metal transfer, and reheating operations
  • Non-ferrous metals: for melting and metal transfer with refiners and smelter
  • Foundries: for melting with cupolas and rotary furnaces and for metal transfer
  • Semi-finished products: for reheating furnaces and heat treatment, with protective atmospheres for galvanizing and annealing
We leverage our skills and technologies to deliver reliable and competitive gas supply.

Metal Fabrication

We have extensive expertise in metal fabrication across industries that produce steel, non-ferrous structures, vessels, cars, aircrafts and others.

We deliver reliable and competitive gas solutions to our customers, supplied via cylinders, bulk, and on-site production units. Our solutions cover three critical stages in the manufacturing cycle.

Cutting of metallic raw materials

  • Flame cutting using FLAMAL™, a range of oxygen and fuel gases that improve safety, quality and productivity
  • Laser cutting using LASAL™ to improve performance and reliability for high performance jobs

Arc Welding

ARCAL™ is the first arc welding offer that covers most of the market needs with four ready to weld gases (ARCAL™ Prime, ARCAL™ Chrome, ARCAL™ Force and ARCAL™ Speed) and the innovative built-in regulator (EXELTOP™).

Heat Treatment

ALNAT™, the range of metal heat treatment solutions encompassing gas, related handling equipment and services for value-added processes.

Metal fabricators use a multitude of processes that require industrial gases.


Glass is made in furnaces at very high temperatures with a process that requires constant improvement to meet the energy efficiency and environmental challenges posed by the manufacturing cycle.

Air Liquide Thailand provides solutions along all stages of the glass production process, from melting to forming end products. To complete our offer, we deliver a competitive oxygen supply adapted to the needs of our customers, particularly through energy-efficient on-site oxygen generation systems.

Water & Sewage Treatment

Industries must reduce their pollution emissions and improve their processes for maximum reuse of water and materials, while complying with the reinforcement of environmental and sanitary regulations.

At Air Liquide Thailand, we master applications using gas technology to treat water, recycle metal, recover solvents, analyse air quality and recover waste.

Air Liquide experts are in the field to find the best solutions for our customers.

Food & Beverage

Air Liquide Thailand has developed innovative ALIGAL™ food-grade gas solutions, compliant with HACCP (Hazard Analysis Critical Control Point) in order to meet the most rigorous health and safety standards. Whether in freezing, modified atmosphere packaging, product quality and flavour preservation, carbonation, inerting and/or throughout the processing and distribution chains, our goal is to guarantee the safety and high quality of the products for the end users, while increasing the productivity of our partners and extending the product shelf life.

Our goal is to guarantee the safety and high quality of the products for the final consumers.
