As one of Australia’s major manufacturers 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 Australia’s army of vehicle repairers and technicians, our range offers multiple options for most applications.
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.
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.
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.
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.
When diesel is combusted with air in truck engines, the production of various oxides of nitrogen (NOx) is inevitable. To reduce the NOx levels to those required by environmental legislation, the combustion gases are processed using selective catalytic reduction (SCR). AdBlue® is added to the SCR system and urea, which is the active ingredient of AdBlue®, decomposes at the high temperatures in the flue gas to form ammonia which reduces the NOx back to nitrogen over the SCR catalyst. To dose the appropriate level of AdBlue® it is necessary to measure the NOx levels and adjust the injection rate accordingly. But having solved the NOx emissions problem, it is of course not acceptable to create an ammonia emissions problem, so fine tuning of the process control is achieved with ammonia slip measurement in the final exhaust gas emitted from the SCR.
In a modern diesel engine, both the NOx and ammonia levels will be measured using gas sensors and the data will be processed in the on board diagnostics or engine management control system. Production of these engine gas sensors relies on extremely tight blend tolerance specialty gases mixtures for quality control. For some calibration gas mixtures it is traceability, accreditation or low measurement uncertainty that is the critical factor, but in the case of low blend tolerance mixtures, hitting the exact requested gas mixture concentration is the core customer requirement. To achieve that, at our Coregas specialty gases production facility in Yennora, we use high precision gravimetric filling techniques to make sure that we can hit the bullseye every time and deliver the exact products that our customers need.
