Air Liquide in India Service & Parts

Service & Parts


Brazing processes can be manual or automatic. They are used for heat exchangers in air conditioning, taps, sanitary equipment and compressor parts. Fuel gases include acetylene, hydrogen, and Air Liquide’s FLAMAL™; brand gas mixtures.

Gases : Acetylene Hydrogen


Emissions testing and calibration for mobile engine applications

Specialty gases from Air Liquide deliver classic performance that is destined to become an industry benchmark for compliance and value in engine emissions testing. Pure air, nitrogen and FID fuel will help your site comply with Part 1065, Part 86 and Euro VI regulations. Scott™ brand calibration standards are directly gaseous NIST-traceable and ISO 17025 accredited. Purity, accuracy, reliability and speed of delivery of these specialty gases improve analysis reliability for added compliance assurance. In addition, our gases will decrease operational costs by eliminating test cell downtime due to “inaccurate” gases.

Gases : Carbon Dioxide Hydrogen Nitrogen Oxygen ALPHAGAZ™


Hydrocarbon Emissions Testing

The Environmental Protection Agency (EPA) revised 40 CRF Part 1065 in April 2014 to include nitrogen balance gas as an alternative option to helium with hydrogen for FID fuel in the automotive industry for hydrocarbon emission testing. Blend tolerance of the FID fuel has also been modified to 40±1% (0.39 to 0.41mol/mol) hydrogen in the revised regulations to minimize its impact on analyzer response. Our Scott™ brand Standard FID fuel meets Part 86 requirements. Scott brand FID fuel 1065 meets Part 1065 requirements. A carbon dioxide specification can be added for Euro VI compliance.

Gases : Hydrogen


Local Engine Inspection and Testing

Air Liquide is the leading supplier of gases used in local emissions testing garages. Many states employ a certification process to qualify gas blenders for use in decentralized state programs. One of the most often referenced certifications is from California's Bureau of Automotive Repair (BAR). Air Liquide meets state certifications as well as Federal EPA I/M 240 and ASM specifications. We also offer the most widely utilized BAR products and their components; these mixtures are ±1% accurate and NIST-traceable.

Gases : Carbon Dioxide Propane


MIG and MAG Welding

Metal Inert Gas (MIG) welding mixes are mainly used for sensitive stainless steels and aluminum or copper-alloy welding.

Metal Active Gas (MAG) welding is highly flexible and adaptive, and used when you wish to obtain high productivity and high quality results. This process is used for manual (semi-automatic) welding or automated/robotized installations on low-alloy carbon steels, high-alloy stainless steels or non-ferrous alloys such as aluminum or copper.

Gases : ARCAL gases Argon Carbon Dioxide Oxygen


Our ARCAL™ brand offers a full range of high-quality, ready-to-use gas solutions for welding, shielding and cutting applications to help you boost the efficiency and overall productivity of your operations.


Powder Coating

Powder coating is for applications involving hardfacing pieces as molds and using manual powder guns with oxy-acetylene flame processes.

Gases : Acetylene ARCAL gases
