FAQ：
|
Q1. What is your warranty period?
|
|
Our payment terms is 1 year or 1000 running hours whichever comes first. But based on some special project, we can extended our warranty period.
|
|
Q2.Does your generator have global warranty?
|
|
Yes, most of our products like powered by Cummins engine , powered by Perkins engine, Doosan power generator enjoy the global warranty service. And the alternator we use like Leroysomer, Stamford, marathon also enjoy the global warranty service, so you do not need to worry about the aftersales service.
|
|
Q3.What is the difference between standby, continuous, and prime power ratings?
|
|
Standby power generators are most often used in emergency situations, such as during a power outage. It is ideal for applications that have another reliable continuous power source like utility power. It’s recommend usage is most often only for the duration of a power outage and regular testing and maintenance.
Prime power ratings can be defined as having an “unlimited run time”, or essentially a generator that will be used as a primary power source and not just for standby or backup power. A prime power rated generator can supply power in a situation where there is no utility source, as is often the case in industrial applications like mining or oil & gas operations located in remote areas where the grid is not accessible.
Continuous power is similar to prime power but has a base load rating. It can supply power continuously to a constant load, but does not have the ability to handle overload conditions or work as well with variable loads. The main difference between a prime and continuous rating is that prime power gensets are set to have maximum power available at a variable load for an unlimited number of hours, and they generally include a 10% or so overload capability for short durations.

Q4.How could I trust u?
|
|
Diesel Service & Supply stands behind the quality of all the used generators and industrial power equipment we sell. If you are not convinced by the pictures, videos, check-in reports, load tests, customer experiences and sales associates’ knowledge about the generator you are interested in, then we invite you to come visit our expansive yard and shop facility to witness a load test and see the professional operation we have going on here.
