Smart environmental monitoring solutions

What we do

Norditech has over 14 years of experience designing and maintaining continuous emission monitoring systems (CEMS) for facilities across Australia.


Expertise in Continuous Emissions Monitoring

Public and private industrial operations from mining to landfills are under increasing pressure to control, monitor, and mitigate stack air pollution.  The EPA’s Clean Air Regulations set in-stack emissions limits for pollutant concentrations at the point of release, and facility operating licences require emissions monitoring on a continuous basis.

Non-compliance with licence requirements or failure to control heavy emissions can result in increased scrutiny by regulators, steep fines, or even plant shutdown.  For this reason, it is critical to have a monitoring system you can rely on.

Norditech boasts over 14 years of experience in designing and maintaining Continuous Emissions Monitoring Systems (CEMS) for facilities across Australia. Our clientele, comprising of glass factories, power stations, incinerators, and tunnel ventilation stacks, operate round the clock and require a dependable support system and responsive technical team.

We understand the crucial role a robust and dependable solution plays in the smooth functioning of your facility and your peace of mind.


Our Approach

Our foremost objective in every project is to comprehend our clients’ needs. We then suggest practical and cost-effective solutions that align with your compliance targets and project budget, which can include maintenance, site assessment, project management, design and installation, data acquisition, validation, and reporting, as per the project scope.

For optimal process control and stack emissions monitoring, industrial facilities require robust and durable monitoring equipment capable of continuous operation in challenging conditions. We prioritise reliability and low maintenance while selecting gas and particulate analysers for your facility.

Our field engineers possess extensive expertise in Continuous Emissions Monitoring Systems (CEMS), and we offer a comprehensive range of tailor-made CEMS products. This enables us to provide customised systems that optimise efficiency and minimise maintenance costs.

At Norditech, we manufacture fully engineered and integrated systems in our factory, which are then installed by qualified technicians on site. This guarantees proper workmanship and system integration to meet your project specifications precisely.
