Alliance Technical Group has a dedicated CEMS service line with experts that manage the full operational and maintenance responsibilities for CEM systems across multiple industries. With Alliance’s national coverage of qualified CEMS resources, we can ensure comprehensive support from the initial full system buildout to the long-term functionality of your system with 24-hour support, seven days a week. Our specialists are proficient in complex national and regulatory requirements, making them an essential partner in finding the right solutions for you.


Alliance assists customers in meeting their regulatory and industrial requirements by planning, designing, integrating, and supporting CEM systems. Our systems are designed for accuracy and reliability. We have a spare parts inventory essential to avoid compliance risks and reduce downtime. When necessary to ensure continuous compliance status, we can provide temporary CEMS.


Responsiveness is central to our service philosophy. Alliance can provide CEMS support that provides 24/7/365 responsiveness. The service guarantees Alliance will respond to calls day or night.


Training is integral to operating and maintaining a CEM System. We offer several levels of training for plant operators, technicians, and management personnel customized to your site-specific equipment.


Alliance supplies a full selection of CEMS spare and replacement inventory required to operate CEM systems to eliminate potential operational downtime.

Upgrading CEMS equipment is necessary due to newer equipment technology, changing regulatory requirements, or obsolete system components. We can provide equipment and services to upgrade your CEMS with newer, more reliable, and more accurate analyzers. System upgrades provide an excellent opportunity to conduct system modifications to increase CEMS accuracy, ultimately reducing previously overreported emissions.
