About ENVEA
ENVEA is an environmental measurement group that makes continuous emissions monitoring systems (CEMS), gas and mercury analyzers, particulate monitors and process instruments. In the United States it operates as ENVEA Inc., headquartered in Geneva, Illinois, the former home of Altech Environment U.S.A. The group was founded in France in 1978 as Environnement S.A. and adopted the ENVEA name in 2018.
What ENVEA makes
ENVEA can supply a single analyzer or a complete integrated monitoring system. Its gas analysis range spans NDIR gas-filter correlation, FTIR, chemiluminescence, heated FID and paramagnetic O2, in both extractive and in-situ configurations. The MIR 9000 extractive analyzer and the stack-mounted MIR IS are the core CEMS workhorses.
Around the gas analyzers, ENVEA builds out the rest of the stack: reagent-free mercury CEMS such as the SM-5, light-scattering and electrodynamic dust monitors for emissions and bag leak detection, and STACKFLOW ultrasonic velocity monitors for mass emission rates. Sample conditioning, probes, calibration units, shelters and WEX reporting software complete a system.
Beyond the stack, ENVEA offers ambient air quality analyzers and sensor networks, plus microwave and radar instruments for bulk solids flow, moisture and silo level. Private equity firm The Carlyle Group took a majority stake in 2020, and the group has since added companies including California Analytical Instruments, whose US-built NDIR, FTIR, CLD and FID analyzers joined the ENVEA line in 2023.
Why engineers specify ENVEA
- EPA-oriented product listings. ENVEA lists the MIR 9000 and MIR IS for 40 CFR Parts 60 and 75, the SM-4 and SM-5 for PS-12A, STACKFLOW monitors for PS-6 and the MP101M as a US EPA Federal Equivalent Method for PM10 and PM2.5.
- Dual certification. Many of the same instruments hold TÜV QAL1 approval to EN 15267 and UK MCERTS, which helps operators that apply one monitoring standard across US and international sites.
- One supplier for the whole system. Gas, mercury, dust, flow and data handling can be sourced and integrated together.
- Practical sampling options. In-situ drying on the MIR IS and extractive evaporation on ProScatter Extractive address wet and corrosive stacks.
Local support from Vaughn Associates
Vaughn Associates represents ENVEA in its Louisiana and Gulf Coast territory, covering Louisiana, South Mississippi, South Alabama and the Florida Panhandle. That corridor is dense with refineries, petrochemical and chemical plants, and power generation sources that answer to EPA monitoring rules.
Our Baton Rouge-based team helps you define the measurement list, sampling approach, applicable performance specifications and data handling requirements before a quote is built. We coordinate pricing and technical questions with ENVEA’s US engineers and stay involved through submittals and delivery. Systems are typically purchased directly from ENVEA.
