Aurora Generators 20kW Perkins Diesel Generator/Open Enclosure - PowerGen USA - AGi20P-O
THIS SIZE GENERATOR IS PERFECT FOR, In the event of an outage, you have enough power and the ability to carry on as if it never happened. In extreme conditions, it might not be enough for the oven, stove and central air plus dryer all at the same time.Â
JUST TAKE A LOOK AT WHAT YOU GET:
Long Runtime Diesel-powered engines can work hard 24/7 for extended periods - up to 3 weeks if necessary - and still outlast any other type of engine for a fraction of the operating costs.Â
ReliabilityÂ
There's a reason the farming, transportation and construction industries have been leveraging the benefits offered by diesel generators for years.
Home FriendlyÂ
New stringent emission regulations have produced clean diesel engine options that fit perfectly for home power generation. These strong, reliable long-life diesel engines have become today's preferred choice for home backup power.Â
Clean and SafeÂ
Diesel fuel is a cleaner fuel that can be safely stored for long periods.
Quieter RunningÂ
The higher the RPM, the louder the noise. Our diesel generators run in the 1800 RPM range, unlike non-diesel products that run at 3600.
Low MaintenanceÂ
You only need to change the oil and filter every 500 hours instead of every 100 hours for a non-diesel generator.
Cost-EffectiveÂ
Diesel fuel is the least expensive to run, with natural gas and propane costing much more.
Flexible WarrantyÂ
Diesel-powered generators seldom have any restrictions on use and can be used non-stop if needed. The warranty for natural gas, propane and gasoline-powered generators usually only covers emergency standby use.
