Industrial facilities running CEMS hardware face a problem the hardware vendors never solved: the data your stack analyzers produce every minute sits in a silo completely disconnected from the maintenance team responsible for keeping that hardware accurate and compliant. OxMaint bridges that gap — connecting your CEMS data stream directly into a CMMS that auto-schedules calibrations, logs every QA event, and generates EPA-ready reports without manual assembly. Start your free trial or book a live demo to see your plant's CEMS data inside OxMaint in under 15 minutes.
Your CEMS Monitors Emissions.
OxMaint Makes Them Defensible.
Automated data ingestion · Calibration scheduling · Audit-ready regulatory reports — from one connected platform.
The Compliance Gap Nobody Talks About
CEMS hardware is mandatory. Under 40 CFR Parts 60 and 75, facilities burning fossil fuels must continuously monitor SO₂, NOₓ, CO₂, CO, and stack flow — and the data must be legally defensible. Yet most facilities manage that data through a patchwork of exported CSVs, manual QA logs, and annual consultant-produced reports that take weeks to compile. The hardware is running. The data is being generated. But the system connecting data quality to compliance readiness is broken.
What CEMS Integration with OxMaint Actually Does
This is not a data visualization layer bolted onto your existing system. OxMaint's CEMS integration creates a two-way operational link: CEMS data flows in and triggers maintenance actions, calibration schedules, and compliance events. Maintenance records flow out and attach to your regulatory submissions as verifiable audit evidence.
The CEMS Calibration Problem — Visualized
Calibration failures are the single biggest cause of CEMS data invalidation under EPA regulations. A missed cylinder swap, an undocumented span check, or a response time test performed outside the required window can invalidate hours of emissions data — triggering substitute data protocols and potential violations. Here is how the CEMS maintenance lifecycle looks without vs. with OxMaint.
Regulatory Frameworks OxMaint Supports for CEMS Data
CEMS compliance is not a single standard — it is a layered set of federal, state, and international obligations that each require differently structured data outputs. OxMaint maintains native alignment to all major frameworks relevant to facilities operating continuous emissions monitoring systems.
What Gets Integrated — Your Full CEMS Asset Ecosystem
A CEMS is not a single piece of equipment — it is a system of components, each with its own maintenance interval, calibration requirement, and compliance implication. OxMaint tracks every component as a managed asset, building a complete maintenance and compliance picture from analyser to data acquisition system.
