Systems
We have decades of experience building high-quality
CEM Systems
to customer’s unique specifications.
ESC Spectrum designs and tailors CEM Systems to meet the toughest monitoring challenges.
We construct CEMS in compliance with Environmental Protection Agency, state, and local regulations based on an in-depth knowledge of the process, monitoring and ancillary hardware, control system, and reporting software requirements involved.
Our expertise in dilution, extractive, in-situ, and hybrid CEMS ensures systems that surpass expectations.
We consider your permit, process, and space requirements to provide a unique system that is within budget, tested, and proven.
We are experts in Process Control CEM Systems.
ESC Spectrum can solve challenges specifically related to designing a Process Control Monitoring System. We design systems tailored to accommodate monitoring locations located upstream of control devices in stratified and heavy particulate-laden gas streams.
We include PLC interfaces in the design of the system to ensure that real-time monitoring data is fully integrated.

We create technician-friendly, state-of-the-art mobile testing CEM Systems.
Mobile testing systems operated by stack testers and process optimization teams can present design challenges. These challenges are best understood by a system integrator with employees actively engaged in testing activities.
We handcraft each mobile system and include multiple options for power, lighting, HVAC, shelving and storage, weight requirements, flooring, and testing analyzer configuration.
Each mobile testing trailer is built with high-quality components, ensuring long life with minimal maintenance. The trailer layout is optimized for ease of use so technicians can complete their work as efficiently as possible.

We provide a full suite of CEMS services to support your systems.
ESC Spectrum offers total CEMS solutions from a single source. We are a turnkey provider for shelters, testing, parts, repair, maintenance, and more – everything you need to keep your CEMS system healthy and in compliance.
