Doosan Portable Power is adding three new models — G25, G50 and G70 — to its mobile generator lineup.

The G25, G50 and G70 mobile generators feature a long list of innovations based on customer input. The newly packaged Tier 4 Final-compliant generators offer improved fuel efficiency, extended runtimes and lower sound levels.

The G25, G50 and G70 models are the first mobile generators equipped with Doosan-built engines — the D18, D24 and D34 respectively. The high-performance engines deliver increased fuel economy, improved motor-starting capability and reliable operation in extreme conditions. The D18 and D24 engines are designed with a dieseloxidation catalyst (DOC) aftertreatment system, which is virtually maintenance-free. The D34 engine consists of DOC with selective catalytic reduction (SCR) aftertreatment.

The introduction of the G50 mobile generator marks a size increase in the line of generators. The G50 (51 kVA) replaces the G40 (35 kVA) generator, a change driven by customer demand for higher kVA output.

Another customer-driven feature of the new lineup is increased onboard fuel capacity for runtimes in excess of 24 hours at any load factor. An optional 48-hour runtime solution is available on the G25 and G70 models. The newly-packaged generators are also quieter than previous models; most notably the G25, which features sound levels at 63 dBA.

“These multipurpose generator models are popular rental items, especially for general construction and event applications where extended runtime without refueling and low sound levels are required,” says Todd Howe, global generator product manager at Doosan Portable Power.

The generators also feature enhanced controls for easy operation. The new Doosan engine controller includes a backlit LCD screen for easy viewing of common parameters while analog gauges allow at-a-glance monitoring for operator convenience. Fault codes are displayed in simple text for faster diagnostics and troubleshooting. The new controls are also designed to allow integration of a variety of telematics packages for customers that desire remote monitoring capability.

Further expanding the models’ versatility is a dual-frequency feature that allows an operator to select 50 Hz or 60 Hz, dependent upon the application, and a multi-voltage selection switch.
