Doosan Portable Power’s new mobile generators
By Andrew Macklin
February 9, 2016 – Doosan Portable Power now offers three newly designed models to its mobile generator lineup — G25, G50 and G70. The G25 was on display at its outdoor booth at World of Concrete in Las Vegas.
The G25, G50 and G70 mobile generators incorporate numerous innovations based on customer input and are aimed at improving operator experience. The newly packaged Tier 4 Final–compliant generators offer improved fuel efficiency, extended runtimes and low 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, strong motor starting capability and reliable operation in extreme conditions. The D18 and D24 engines are designed with a diesel oxidation 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 marked a size increase in the Doosan Portable Power generator product line. The G50 (51 kVA) replaced the G40 (35 kVA) generator, a change driven by customer demand for higher kVA output.
Another customer-driven feature of the G25, G50 and G70 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 one of the industry’s lowest sound levels at 63 dBA.
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.
Doosan Portable Power generators are designed to withstand rugged transport and jobsite needs. Built on heavy-duty skid bases, the generators boast a 14-gauge, galvannealed steel enclosure and rugged running gear for easy towing.
