Doosan Portable Power did not ignore the suggestion box.

The North Carolina-based company has introduced three new mobile generators that offer improved performance based on customer feedback.

The G25, G50 and G70 mobile generators, all of which are Tier 4-Final compliant, offer improved fuel efficiency, extended runtimes and the industry’s lowest sound levels. Doosan says the new generators were engineered using customer input.

The G25, G50 and G70 models are the first mobile generators equipped with Doosan-built engines: the D18, D24 and D34 respectively. Doosan reports that the high-performance engines deliver increased fuel economy, unrivaled motor starting capability and reliable operation in extreme conditions.

The D18 and D24 engines are designed with a diesel oxidation catalyst (DOC) after-treatment system, which is nearly maintenance-free. The D34 engine consists of DOC with selective catalytic reduction (SCR) after-treatment.

“The Doosan powertrain allows our Doosan Portable Power authorized dealer network to provide end-to-end service and full warranty support, offering customers the advantages of a single source for all maintenance and repairs,” said Todd Howe, global generator product manager, Doosan Portable Power.

The introduction of the G50 mobile generator marks a size increase in the Doosan Portable Power generator product line. 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 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.

“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,” said Howe.

The new generators also feature enhanced controls for easier operation. The new Doosan engine controller includes a backlit LCD screen for better viewing of common parameters while analog gauges allow at-a-glance monitoring for operator convenience.

Fault codes are displayed in simple text which is intended to allow 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 feature a 14-gauge, galvannealed steel enclosure and running gear for towing.
