Industrial
generators are usually rugged and will work for decades. After that, the engine
can be reconditioned and the unit works like new provided the alternator coils
have not been subjected to excess loading. This is not the only issue with
buying used generators. Consider these tips and make an informed buying
decision.
Background
of the generator
If it is
possible find out how much the generator was used before it was disposed off.
Most industries buy new generators and keep them in standby mode whereas
some may have made continuous use of the system as a prime power source. Look
at the age, hours of use, make and model and its condition.
Buy through
a generator selling company
Instead of
buying used generators directly, it is advisable to buy from a seller who
purchases and refurbishes generators. They carry out a thorough check of the
engine, carry out repairs where necessary and then put it through tests to
ensure the engine works as good as new. They also check the alternator unit
coils and the generator switchgear, carrying out repairs or replacement
as may be necessary. He will also inspect and replace bearings and bushings. You
pay a slightly higher price but far lower than what you would pay for a new
unit yet get a generator that is as good as new and just as dependable.
Load
test
A seller
may claim the new or used generator is best performing one. Insist on a load
test and even overload the generator by 25% to see how much it heats up. A
dealer specialising in new and used generators will gladly offer this test to
give full satisfaction. The generator he sells will carry a full guarantee,
giving additional peace of mind.
Buy only
after these checks and from a seller who can offer maintenance support.
