Frequently Asked Questions

What is required for SCAQMD Rule 1146 low-NOx boiler compliance in Southern California?
The South Coast Air Quality Management District requires commercial and industrial boilers to operate under strict nitrogen oxide (NOx) emission limits (typically 9 to 12 ppm). We tune flue gas recirculation (FGR) and burners to certify compliance.
What does annual CSD-1 boiler safety testing cover?
CSD-1 testing verifies that automatic low-water cutoffs, high-limit pressure switches, flame safeguard scanners, fuel safety shutoff valves, and relief valves operate reliably to prevent boiler explosions.
How much energy does ultrasonic steam trap surveying save?
A single blown steam trap can waste over $10,000 in steam per year. Our ultrasonic and thermal imaging surveys identify failed traps to restore boiler loop efficiency.
