A diesel generator's exhaust releases a significant amount of unwanted particulate matter (ranging from carbon monoxide and hydrocarbon to volatile organic compounds and hazardous pollution) into the air. This is unwanted in any circumstance but is particularly undesirable when situated near a school, daycare, or nursing home or the generator is positioned in a way that the exhaust can be sucked back into your building's ventilation system.
A diesel particulate filter (DPF) traps particulate matter - also known as soot - from the engine's exhaust; maximizing the reduction of particulate matter emitted by your generator (up to 90% or more) as well as minimizing diesel smoke and odor. Additionally, when the engine exhaust reaches a certain temperature, the particulate matter captured in the filter is oxidized and burned off; effectively cleaning itself (this is called 'passive regeneration') and extending its usefulness. Some DPFs are also designed to reduce the noise level of the engine, eliminating the need for a separate silencer or muffler.
A number of different regulatory, environmental, noise, and smell factors are increasingly creating challenges. A combination of the right engineering and new offerings from DPF manufacturers can provide a custom solution for most situations. Look into a CARB Level 3+ verified DPF system, designed for diesel engines of all operating conditions. This could be a great solution for your Emergency Standby Power System.

Do you have generators with dual starters & battery sets for redundancy? How many battery chargers are supporting your battery sets? If you answered “one battery charger”, this is your primary risk area.
If your only battery charger fails, you no longer have the ability to charge all four batteries, and therefore have lost the redundancy that was designed into your starting system. Dual starting systems for generators and fire pumps should have dual battery chargers to ensure the highest level of reliability.
For life safety systems and mission critical systems, dual battery chargers for 24 volt systems can reduce starting risk when your systems are called upon during a power outage or fire.

The single most important step you can take to preserve your equipment's value and dependability is to...
Run Your Unit Every Week!
Why is this so important? Quite simply, engines are made to run - not sit idle in readiness for an emergency. When they sit, all sorts of bad things can happen. Air can get into the fuel lines, lubricating oil can drain from the rubbing parts, water can condensate on electrical parts, and many more. In contrast...
By running your unit each week (called "exercising the unit"), you accomplish the following:
a) make the unit happy by preventing bad things from happening and, equaly important,
b) you get positive verification your unit is ready for a power outage.
Most units have some type of "exercise clock" that will automatically exercise the unit. If you are not sure, call.

Unless you maintain your Automatic Transfer Switch (ATS) each year, you risk failure of your emergency power system just when you need it -- and that’s when the power goes out.

Insulation resistance testing is a specialized procedure where the integrity of the electricity producing portion of your generator set (alternator) is tested in a safe & isolated condition. During the test, DC voltage is applied to the alternator windings to determine if the insulation is damaged and may cause a short circuit under normal operation. This test is a crucial part of maintaining a reliable on-site emergency power producing plant and is recommended annually by NFPA 110. This test can identify and prevent catastrophic failures to not only the generator set, the Automatic Transfer Switch as well as anything on the entire emergency load circuit.
This test identifies weakness of the dielectric strength of the internal components that may under normal conditions not be detectable until a total failure occurs. Identifying these impending failures is a relatively simple process and typically will not impact any supported building systems. If problems are found, steps can be taken to ensure your on-site power needs are met and costly damage to your entire emergency circuit can be avoided.
