Four redesigned mobile generators have Tier 4-Interim engines: G150, rated at 122 kW; G190, at 155 kW; G240, at 190 kW; and G325, at 261 kW.
Four redesigned mobile generators have Tier 4-Interim engines: G150, rated at 122 kW; G190, at 155 kW; G240, at 190 kW; and G325, at 261 kW. Analog control panel has large, brightly lit meters. Onboard engine diagnostic display panel includes controls and indicators required to operate the aftertreatment regeneration system. Dual frequency capability is now standard to enable the units to power 50Hz applications with the flip of a switch. Connection panels are more accessible, with more wiring connections available. Sound levels were reduced by as much as 5 dBA. Cooling system is now housed in a separate compartment and uses electric cooling fans and a state-of-the-art radial-fan. Services intervals are 500 hours, and increased onboard fuel capacity provides longer run times.
Two propane-powered mobile generators, the 50-kVA 50REZGT and 70-kVA 70REZGT, use naturally aspirated engines.
Doosan has taken its P185 and C185 air compressors to Tier 4-Final, along with its G240WCU generator.
The P185 and C185 compressors are now powered by a Tier 4-Final, 49-horsepower Deutz D2.9 L4 electronic engine.
Electric-driven VP900e portable air compressor replaces the typical diesel engine on the air compressor with three onboard electric motors that are controlled by a variable frequency drive (VFD) system—one airend motor and two cooling fan motors— each sized specifically for their dedicated function.
