FAQ
What is the difference between prime and standby power ratings?
Prime power ratings are for continuous operation, while standby ratings are for emergency backup. Prime power is typically 90% of the standby rating.
How often should I maintain my 140kW generator?
Regular maintenance is recommended every 250-500 hours of operation, with major overhauls every 8,000-10,000 hours.
What fuel types can 140kW generators use?
Most commonly diesel, but some models can run on natural gas or propane. Dual-fuel options are also available.
How long can a 140kW generator run continuously?
Modern units can run for 24-48 hours on a full tank, with some mobile models offering up to 25 hours of runtime.
What safety features should I look for in a 140kW generator?
Automatic shutdown systems, overload protection, low oil pressure sensors, and high temperature safeguards are essential.
How much space does a 140kW generator require?
Mobile units typically need at least 120 square feet of clear space, while stationary models require more depending on the enclosure type.
What are the noise levels of 140kW generators?
Most modern units operate at 70-75 dBA, equivalent to a vacuum cleaner, with sound-attenuated enclosures available for quieter operation.
How do I choose between a mobile and stationary 140kW generator?
Mobile units offer flexibility for temporary sites, while stationary models provide permanent power solutions with less maintenance.
What environmental regulations do 140kW generators need to comply with?
They must meet EPA Tier 4 emissions standards and local noise ordinances, with some models also complying with California’s CARB requirements.
How do I calculate the power requirements for a 140kW generator?
Add up all connected loads, including startup surges, and ensure the generator’s capacity exceeds the total by at least 10-20% for safety margin.
