Meeting the EU Stage IIIA engine emission regulations for generators, the new G40-IIIA (40 kVA prime power) and G60-IIIA (60 kVA prime power) generators are launched by Doosan Portable Power. Sharing a similar design and characteristics to the two platforms G150-G200-IIIA and G80-G100-IIIA respectively launched in 2012 and 2013, the new generators offer robustness and reliability, high performance and a wide choice of features to meet the needs of temporary power applications.
From the construction site, to the concert stage, to the front lines of disaster relief efforts, the new generators offer rental companies, contractors, event organizers, emergency services, general industry and many other customers the highest quality, backed by dedicated technical and service support worldwide.
Of particular interest for the rental market, the G40-IIIA and G60-IIIA generators will be available with two different frame-fuel tank configurations. The standard configuration will ensure autonomy of at least 10 hours at 75% of the load, the 24 hours fuel tank configuration will be available as option. Both frame-fuel tank configurations offer a containment base integrated as standard feature to ensure retention of 110% of all powertrain fluids.
As fuel quality and storage are major concerns for rental companies, routine fuel tank maintenance has been simplified with special attention to the fuel tank cleaning and port draining processes. A 3-way fuel supply valve is available, as a modular option, which, when linked to an external fuel connection module, provides maximum autonomy. A manual engine oil sump pump option is also available.
Safe, flexible operation
Safe and easy access to operation and maintenance areas has been a priority throughout the design of the new generators. Accessibility to key areas, including the centrally positioned lifting eye, engine radiator compartment and maintenance points, has been improved. The air flow has been optimized throughout the generator unit to meet cooling requirements for locations with high ambient temperatures, without deration impact on the electrical output performance. The sound attenuation LwA rating of the generators meets or exceeds the relevant European regulations.
A user-friendly feature is the electrical control and power compartment which has been designed to meet the highest safety, reliability and flexibility requirements. All control functions are grouped together on a common, simple-to-use operator control panel with easy-to-read analogue gauges displaying critical operating parameters at a glance.
A digital control panel version, offering extended parameter measurements and historical storage of events and alarms, is available as an option. A new switchable dual frequency 50/60 Hz feature is available with the digital controller for both models (option). The new generator units are EU Stage IIIA emission compliant at both 50 and 60 Hz frequencies.
The power supply pedestal features as standard a busbar connection with Schneider main 4-poles circuit breaker and fixed 300mA electrical protection for both models. The adjustable earth leakage relay is still available as option, as well as the grounding/neutral regime selection module.
The output performance stability of the generators is ensured by an efficient powertrain featuring a combination of Yanmar and John Deere Stage IIIA engines, both available with electronic speed regulation, and Leroy Somer alternators. The Leroy Somer alternators utilise the AREP excitation system, providing best-in-class motor-starting performance. This system is ideal for powering pumps, cranes and other applications with high start-up demands.
To increase long term reliability in harsh environments, both generator models feature as standard ‘heavy duty’ (level 2) protection for the rotor and stator windings. Upgraded alternator windings protection (level 4) is now available as option for all models of the generator product range.
