Automotive and transport

As a major manufacturer of industrial gases, Coregas has decades of experience in the development, manufacture and application of specialised automotive and transport gases.

From working with leading manufacturers and technologists on innovative transportation projects, to supplying New Zealand’s army of vehicle repairers and technicians, our range offers multiple options for most applications.

Gases for transport

Shielding, welding and cutting gases

Our large range of shielding, welding and cutting gases has options to suit every application. Many of our sales team have worked in welding previously, so can provide advice on optimising your application.

Refrigerant range for mobile air conditioning

This range includes the latest, more environmentally friendly options. For more information about our refrigerant range, speak to your local sales representative or contact our Customer Service team.

Hydrogen to power cars and buses

We are working with top car manufacturers as they develop Australian models that use clean burning, high purity hydrogen for the special electric fuel cells that drive the engine. See the case study below for more details of the hydrogen refueling station we helped set up at Hyundai's headquarters in Sydney.

We are also working with bus manufacturers that either use high purity hydrogen as the main fuel source or use it as an additive to improve combustion in existing engines.

Other gases

We have a full range of other gases, eg nitrogen for tyre filling, so we can offer a complete package of gases to fulfill all your gas requirements.

Plus Coregas goes beyond simply supplying gas: we can actively work with you to optimise your process for quality, improve productivity or solve your application issues. For instance, our application engineers can provide on-site assistance in making optimal use of the Coregas range.

If you have a special requirement or the gas you require is not currently listed on our website, get in contact as we may still be able to assist. Our team will be pleased to discuss your requirements, advise on availability and arrange a visit or quote.

Case Study

Hyundai cars - powered by Coregas

When Hyundai chose to build and test a new hydrogen-powered concept car, the Hyundai ix35 Fuel Cell, it chose Coregas hydrogen to fuel the new vehicle. We worked closely with Hyundai and international partners to provide a refueling station at Hyundai’s Australian headquarters in New South Wales.

Coregas supplies high purity compressed hydrogen to the refueling station, which is a special hydrogen storage and dispensing system. When mixed with air, hydrogen burns ‘clean’ leaving only water, reducing the environmental impact of hydrogen-powered vehicles.

Whilst countries in Europe and America already had hydrogen-powered cars and buses, and had begun installing networks of refueling stations along “hydrogen highways”, Hyundai’s concept car was the first vehicle of its kind to be permanently imported into Australia.

Automotive and Transport Gas Applications

Coregas supplies industrial, specialty and refrigerant gases used across automotive workshops, fleet maintenance, transport depots and mobile service teams. Typical applications include shielding gases for MIG and TIG welding, oxygen and fuel gas for cutting and heating, refrigerants for mobile air conditioning, nitrogen for tyre inflation and purging, LPG for forklift fleets, and specialty calibration gas mixtures used for emissions testing and analyser calibration.

Welding, Cutting and Fabrication in Workshops

In automotive repair, fabrication and heavy transport maintenance, gas selection impacts weld quality, productivity and consistency. Coregas supplies argon for inert shielding, argon-based mixtures for MIG welding, and higher performance mixes for stainless and alloys used in exhausts, pipework and custom fabrication.

Common workshop use cases

  • MIG welding (mild steel): Argon and CO₂ mixtures are widely used for clean, economical welds and stable arcs.

  • MIG welding (stainless steel): Stainless shielding mixes can help improve weld profile and working characteristics.

  • TIG welding (stainless and alloys): Higher performance shielding mixes support stainless, nickel and alloy fabrication and repair.

  • Oxy-fuel welding and cutting: Oxygen paired with a fuel gas such as acetylene supports cutting, brazing and heating tasks common in repair shops and mobile rigs.

Mobile Air Conditioning and Refrigerant Gases

Automotive and transport operators rely on correct refrigerants for mobile air conditioning servicing and maintenance. Coregas supplies refrigerant gases and can support selection and supply for mobile A/C requirements, including lower-impact options where appropriate.

Example product within the refrigerant range

  • Carbon Dioxide Refrigerant R744: A high purity CO₂ refrigerant supplied with very low moisture content, designed to help reduce corrosion impacts in refrigeration systems.

Fuels and Fleet Operations

For transport and depot environments, Coregas supports fuel and energy applications used in daily operations.

  • LPG gas: Used across a range of applications including as a fuel to power forklift trucks, and for heating and maintenance processes.

  • Hydrogen initiatives for transport: Coregas NZ has supported heavy vehicle hydrogen refuelling infrastructure in New Zealand through involvement in Halcyon’s green hydrogen fast refuelling station project at Wiri, South Auckland.

Nitrogen for Tyres, Purging and Pressure Applications

Nitrogen is commonly used across automotive and transport maintenance for applications where an inert gas is beneficial. Coregas supplies industrial nitrogen used for tyre inflation and for broader industrial tasks such as blanketing and purging, pressure transfer of liquids and supporting certain heat-treatment processes.

Emissions Testing and Calibration Gas Mixtures

Transport compliance and diagnostics often rely on instruments that must be calibrated to deliver accurate readings. Coregas supplies automotive emissions calibration gas mixtures used for measuring exhaust emissions and supporting calibration of emissions instrumentation for cars, motorbikes and trucks.

Supply Options, Support and Safety

Coregas can supply gases in formats suited to workshop, depot and fleet environments, from portable cylinders through to larger storage options, depending on site needs. Customers can access delivery or collection options, and Coregas provides safety resources to support safe handling, storage and transport of gases.
