WHY TO BUY A
GENERATOR
|
|
The reasons are multiple:
Insuring a safety and a continuity of service in case of
power cut off by the usual supplier.
Feeding in the best cost during the periods of strong
prices of the distributor.
Replacing it in zones not connected to any electricity
network |
The lack of safety and backup facilities may be unacceptable in
some processes of production, and blow a hole in the accounts of a
company.
Whatever the use of the group, and its power, cheaPower will find
a solution for you on second-hand generators market.
For the needs for low power, (often intended for the house, the
trade, or navigation), cheaPower will put you in relation to
distributors more specialized in small powers.
There are many offers and the characteristics of the proposed
machines are very diverse,
that is why you have to define your need as exactly as possible .
The indications below have to guide you in your reflection, and
help you to define the parameters which you will type in the request
form of cheaPower's site.
Do not hesitate to ask questions by e-mail. Our specialists will
answer you as soon as possible. |

GENERATOR'S USE
: PERMANENT OR EMERGENCY ?
|
The
incidence of the usage is consequent on the choice of the product
and its price.
In help, the generator serves a number of limited hours, but
should have to start automatically.
In permanent use, if it is the main electrical source, its
potential of use must be important, and thus the search will
concern a less used or recently reconditioned equipment. |
|
POWER
|
This is
the first parameter to be defined, which characterizes the group,
and strongly influences the price.
You can express the power in kilowatts kW or in Kilovolt-amperes
kVA.
Be careful, there is a variable factor between these two units (of
the order of 0.8) the power expressed in kVA is always stronger
than in kW. (See the explanations in cosPHI page).
This power must be calculated by taking into account all the
powers of your equipments, and sometimes raised to take into
account calls of power to the starting up, for certain equipments.
Define this fundamental parameter with the help of your
electrician.
|
|
PHASE, VOLTAGE
AND FREQUENCY
|
|
|
Three parameters
that everybody knows:
Is your electrical network SINGLE-PHASE OR
THREE-PHASE?
- For the house, he can be single-phase
- For important powers as well as in industrial and
commercial environment,it is most certainly
three-phase. |
|
|
Voltage
- In single-phase, the tension is generally 220 V, or 110 V,
- in three-phase, it is from 380 to 400 V,
- for the strong powers, it may be 5000 V.
But maybe you will need a transformer (to adapt the tension of the
generator to that of your specific use).
Two frequencies: 50 Hz (Europe, Africa, Asia), and 60 Hz ( North
America)
The speed of rotation is 1500 rpm in 50 Hz and of 1800 rpm in 60
Hz. |
|
FUEL
|
|
Choice according to your
source of local supply, its cost, etc... There are
advantages and disadvantages bound to each of the possible
fuels: |
|
-
GASOLINE
o Easy to find
But:
o Very flammable
o Storage period not exceeding one year
o Expensive
o Limited to the small powers
- DIESEL OIL
o Easy to find
o Economic
But:
o 24 months conservation
- NATURAL GAS
o Economic
o Clean Combustion
o No filling
But:
o Availability according areas |
|
PROTECTION
|
Will your
group be installed inside? outside? Must it be SOUNDPROOFED?
The cost increases with the required protections, but
If the generator is installed outside: ask for a hooded version.
If the group group must be silent: ask for a SOUNDPROOF version. |
|
ACCESSORIES
|
You wish
to store more fuel to increase your autonomy, ask for an
additional TANK.
Emergency power unit: it is very significant, for your SAFETY, and
that of your equipment, to envisage a means on connection of the
emergency power unit on your network, to prevent any risk of
accident in the event of re-establishment of the electrical
current provided by your distributor. See CIRCUIT BREAKER,
REVERSER, SWITCH, electrical equipment box.

VALORIZE YOUR
SECOND-HAND EQUIPMENT
|
|
Stocks of surplus and
unutilised equipment accumulate more quickly than one can
sell them, takes invaluable place in the warehouses and
absorbs capital even in companies with very fast growth.
This material is often an unexploited source of income for
its owners. |
|
This
material is invisible in the majority of the companies. The
majority of the companies pay great attention to the management of
the logistic chain, but very little are interested in management
of the nonproductive assets' surpluses.
CheaPower
is one of first Internet broking websites to supply an effective
approach of the management of the assets' surpluses, through its
international network of partners.
