CEMS Done Right.

You call, we answer. Built, supported, and stood behind.

CEMS DONE RIGHT STARTS WITH THE RIGHT PARTNER.

STI designs, integrates, and supports air compliance monitoring systems that perform in the real world.

As one of the the only remaining independent, true integrators, we’re not tied to one manufacturer, and we’re not here to sell you more than you need.

We support the plant, solve the problem, and stand behind the system — long after install.

When you call, STI answers.

No call centers. No runaround.

Just real people who know your system and can help.

TRUE INTEGRATION. NO BIASED SOLUTIONS.

We’re independent by design.

That means we select the right equipment for your facility — not push a single brand.

Better systems. Better outcomes. Built around your needs.

EXPERIENCE THAT SHOWS UP ON SITE

Our technicians work in the field every day.

They understand what it takes to keep systems running — and how to fix them when they don’t.

We don’t just install it. We support it. And when we didn’t install it, we support it anyway.

SUPPORT THE PLANT. SOLVE THE PROBLEM.

Whether we installed your system or not, we help you get more out of it.
From troubleshooting and retrofits to full system integration, STI brings experience, responsiveness, and real support to every job.
