Emissions Compliance Studies

Experienced Provider of Emmissions Compliant Power Systems

Global Power Supply is an experienced provider of backup power systems and related diesel engine emissions compliance regulations. We can help your business meet all emissions requirements for your diesel-powered backup power system. Emissions requirements, as they apply to diesel engines for non-road use, vary greatly depending on geographical location and it’s not always clear which emissions rules apply to which areas. Our team of project managers and engineers has extensive experience installing backup power systems throughout the United States and we work with local regulatory agencies and our own engineers to define and meet applicable emissions requirements, so that your backup power system is permitted and approved by your local regulatory agency.

Global Power Supply sells and rents high-quality power equipment, and we offer rapid delivery services, as well as end-to-end sales, installation, and ongoing maintenance.

Meet Emissions Requirements

To meet government regulated emissions requirements, some diesel generator backup power systems require special diesel particulate filters (DPF) or selective catalytic reduction (SCR) systems in combination with the appropriate emissions tier rating for the engine being used. For larger or more complex backup power systems, especially those in populated or urban areas where emissions compliance regulations are generally stricter, it’s best to study and determine emissions requirements at the beginning of the project so that any additional or customized emissions solutions can be designed, approved, and installed with the rest of the backup power system.

Don’t let your business be surprised by unknown emissions requirements, as they can often lead to months of delay, as well as add additional costs and stress to your project. Global Power Supply can help by leveraging our extensive experience with projects requiring strict emissions compliance. We have an in-house team of seasoned power system engineers and dedicated project managers who will work with your local regulatory agencies to make sure your backup power system meets all emissions requirements.
