GENERATOR INSPECTIONS & Repair
At Prime Diesel Solutions we understand that a down generator can be paralyzing to those relying on it. We take our preventative maintenance, inspections, and repairs very seriously to ensure that every detail is thoroughly examined to help prevent problems and minimize down time.
We customize our protocols and schedule to fit your needs taking into account what the manufacturer of your particular engine recommends.
GENERATOR LOAD BANK TESTING
Load bank testing is another important part of generator maintenance for two reasons. First, of course, is to be certain it is capable of carrying not only the load you require to keep your critical functions running in the event of a loss of power from the grid, but maintain it for a decent amount of time. Secondly, if your generator is only exposed to 30% or less of it's operating capacity, it does not necessarily get the engine to an appropriate operating temperature and pressure level and can lead to *wet stacking (see below). Load bank testing at full capacity brings to light any problems in the cooling system, it seats the rings, and dislodges buildup in the combustion chambers and on the valves. During a load bank test, an artificial load is placed on the generator at slowly increasing kW increments. At each level, measurements are recorded about critical engine parameters, the generator's ability to handle the load, and whether or not it can maintain function at 100% capacity for a sustained amount of time. In order to perform a load bank test, we will bring in a load bank that hooks up to your generator.
*Wet-Stacking is when unburned fuel and soot buildup in the exhaust system secondary to infrequent running or only running light loads. Not only does this effect the performance of your generator, but it can lead to engine failure and is a fire hazard. Load bank testing burns off this excess buildup in a controlled situation.
GENERATOR FUEL POLISHING
We also offer, and strongly recommend, fuel testing and polishing as needed. Fuel is commonly purchased and then forgotten. As time passes, fuel degrades and introduces new issues. With the dramatic decrease of sulfur in diesel fuel since 2007, fuel now degrades faster than ever and poor fuel quality is the leading cause of engine failure. High quality fuel is even more important with the newer, less forgiving, Tier 4 engines. See our Fuel Polishing page here for more information.
