OUMA FAWDE series ultrasilent generators ranging from 8kw to 300kw
are powered by China first top engine FAWDE. As the second biggest
partner for FAWDE in genset application, OUMA receives best service
and support from FAWDE and in barcode system of FAWDE. Engine in
white is unique to OUMA.
All OUMA Ultrasilent generators have features to best suitable for
the local application conditions:
60℃ radiator, no overheat would happen in high temperature weather condition.
To enhance cooling effect, engine oil cooler may be equipped. For
chilly conditions, engine oil heater and water heat jacket would be
used.
65 dbA noise level, quiet enough to leave the users and neighbourhood a good
living environment. We continue improving noise level to below
60dbA.
Four-cavity design of genset housing. i.e. engine and alternator cavity, silencer cavity, radiator and
electronic fan cavity, battery cavity, the genset can run at very
low noise and genset size is quite small. Internal temperature of
the genset housing is kept 40-50℃, safety is ensured while
performance of the genset is maximized. This design is patent
protected to OUMA.
Central AC type cooling fan: 20,000 hours service life, much more than 500 hours as most
genset factories use. The cooling fan connection mode is patent protected
to OUMA.
2.0mm cold-rolled steel genset canopy: rigid and corrosion resistant.
Advanced painting and finishing, no painting colour fade within 5 years.
Battery switch to switch off battery when genset is not in use, so no power loss
of battery.
Fuel non-return valve to prevent fuel returning back to fuel tank and inlet of air to
the fuel pipe, so easy start of genset after long time of non-use.
Competitive price and fast delivery within 20 working days
15 months or 1000 running hours warranty, whichever comes first.
Smallest size and most compact structure, maximum loading and installation space.
