As a Wesfarmers company, Coregas is the only Australian-owned Industrial gases company. They manufacture gases locally and distribute throughout Australia and New Zealand via a network of branches and third parties.

What they do

Coregas provides a complete range of gases and equipment for:

  • Industrial
  • Specialty (including food, beverage, laboratory, pharmaceutical)
  • Healthcare
  • Liquefied and process gas applications

From single cylinders, to cylinder packs and on site vessels of common and rare gases and gas mixtures, their specialty is providing the right gas, in the volume and frequency you require, plus the equipment to work with it. They supply to a range of industries and sectors including manufacturing, welding, laser cutting, pharmaceutical, chemical, universities, government and healthcare.

Production and storage facilities

As far as possible at Coregas, they manufacture our gases in Australia and distribute across Australia and New Zealand. Most of their branches have storage tanks and filling facilities to ensure we can fulfil our next day delivery commitments on stocked gases.

Their main air separation unit at Port Kembla in New South Wales is one of the largest in the Southern Hemisphere, separating air into its main component gases – nitrogen, oxygen and argon – by distillation at cold temperatures. The plant supplies huge quantities of gas direct to BlueScope Steel’s production facility and the rest is distributed to their other customers both in bulk as cryogenic liquids, and as gases.

A smaller air separation unit at Mackay in Queensland guarantees our capacity to supply any volume and in any frequency customers may require.

The team at Port Kembla also run their hydrogen production facility, which supplies BlueScope Steel and all their other customer’s hydrogen gas requirements.

Finally, an acetylene plant based at their head office in Yennora, New South Wales, produces high purity acetylene suitable for everything from instrument calibration to welding.

Quality products and services

As an AS/NZS ISO 9001 quality endorsed company, they aim for top quality in the manufacture packaging and distribution of their gases. All our medical gases conform to Therapeutics Goods Administration (TGA) licence requirements. For specialty gases, their laboratory provides chemical testing and product reference gases, and was the first in the Australian gas industry to receive National Association of Testing Authorities (NATA) accreditation to manufacture reference gas mixtures. This means you can be assured of receiving fully compliant high quality products.

Technical expertise, support and engineering

For cylinder gases, they offer you the latest cylinder technologies such as high capacity cylinders and packs up to 300-bar to enable you to reduce cylinder holdings whilst maintaining the same volumes of gas stored on site.

For bulk and microbulk applications and installations, their team of engineers will work closely with you in understanding your application requirements, to ensure we supply gas and equipment in the most suitable and economic form.

Guarantee of a world class reliable supply

They guarantee a reliable supply of quality gas in the volumes you require. With one of the largest air separation and hydrogen production facilities in the southern hemisphere, they produce oxygen, nitrogen, argon and hydrogen in bulk quantities. Add to this the largest acetylene plant in Australia, plus a helium filling facility, and you can see why we are confident we can meet your needs.

Social responsibility

Coregas and their parent company take our social responsibilities seriously. There is a focus on improving the environmental and social well-being, not only of those organisations or people we interact with directly, but also the wider community and environment.
