Diesel generators FAQ
What is a diesel generator?
A diesel generator is a backup power system that uses a diesel engine to generate electricity when grid power is unavailable or during outages.
What are diesel generators used for?
Diesel generators are used to provide backup or primary power in critical environments such as data centers, hospitals, industrial facilities, and utilities.
What industries use diesel generators?
They are commonly used in data centers, healthcare, manufacturing, telecommunications, and water treatment facilities where uninterrupted power is essential.
Are diesel generators suitable for data centers?
Yes, diesel generators are widely used in data centers due to their reliability, fast response time, and ability to support large-scale backup power requirements.
What factors affect fuel consumption and runtime for an industrial diesel generator operating at partial load versus full load?
Generator load is the primary factor that impacts fuel consumption. A diesel generator operating at partial load will typically consume less fuel than one running at full load. Runtime is based on the available fuel supply. Industrial diesel generators commonly have a subbase diesel fuel tank that is sized for a specific outage duration. For example, a generator sized with a 48-hour subbase tank is designed to have enough fuel to run for 48 continuous hours at full load. If the generator is running at lower loads, that same tank will allow for more than 48 hours of runtime.
How do I size an industrial diesel generator for a facility with large motor starting loads, nonlinear loads, and critical backup power requirements?
Generator manufactures provide an automated sizing tool that allows users to input specific load profiles to properly size the diesel generator. Power Solutions Center
