Product Description
Rain proof design, withstanding all weather 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.
62 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.
