Emissions Controls & Testing
Stay compliant with CARB and SCAQMD
Southern California has the strictest stationary engine emissions rules in the country. We service the aftertreatment systems that keep your generators within permit - and coordinate the source testing that proves it.
Capabilities
What we cover
SCR Systems
Selective Catalytic Reduction service - urea/DEF dosing calibration, injector and pump replacement, NOx sensor diagnostics and catalyst inspection to keep NOx within permitted limits.
DPF & Oxidation Catalysts
Diesel Particulate Filter cleaning, regeneration troubleshooting, differential-pressure sensor service and oxidation catalyst replacement for Tier 2, Tier 4i and Tier 4 Final engines.
Emissions Equipment Upgrades
Aftertreatment retrofits and full equipment upgrades - catalyst replacement, urea/DEF system rebuilds, dosing skid and injector upgrades, and SCR/DPF additions to bring older engines up to current Tier 4 / BACT performance.
Pre-Test Tuning
Engine and aftertreatment tuning ahead of permitted source tests - fuel system optimization, air/fuel trim, DEF system verification and load-bank conditioning to ensure passing results.
On-Site Engine Support
On-site engine and aftertreatment support during source tests - load-bank staging, test-port preparation and live tuning so units run cleanly under the test contractor's measurement window.
Aftertreatment Diagnostics
Portable analyzer checks, opacity readings and DEF/SCR diagnostics to identify drift, fouling or sensor failures before they become a permit problem.
