Punching above its weight1 February 2010
Cummins Power Generation has launched two new new lines of low-range generator sets designed to maximise performance density while minimising environmental impact. Powered by X 1.3 and X 2.5 engines respectively, they are available in 8–11kVA configurations at 50 Hz, and (with the the X 2.5 engine) 17–28kVA at 50 Hz or 12–20kVA at 60 Hz.
Engineered to deliver maximum power whilst occupying a relatively small volume, the new ranges meet the most stringent EU legislation currently in force.
These units carry several proprietary features. A unique feature is the Cummins Excitation Boost System (EBS). This is described as a power enhancing technology that enables smaller sets to deliver the power and performance of larger models without increased running costs and cutting fuel consumption. EBS also provides one horsepower per kilowatt motor starting capacity, and, what the maker describes as exceptional short circuit fault clearing ability together with a low battery warning feature, gives some assurance of an uninterrupted power supply.
The company’s PowerStart 500 controller is fitted as standard, and optional PowerCommand 1.1 digital technology, which provides complete system integration and improved reliability in genset monitoring, control and protection. An intuitive operator interface panel, integrated control functionality and advanced over-current protection are other key features.
Sound attenuated enclosures provide ‘best in class’ quiet operation from 69dB(A) at one metre. The enclosures feature convenient access doors to the engine and alternator service points, forklift pockets on the skid base and inbuilt single-point lifting brackets to simplify on-site installation. With compact dimensions from 1460 x 1130 x 850mm the compact design enables double stacking in the container that saves 50% on transport costs, which means the new range boasts an impressively small carbon footprint as well as a small physical footprint.
Additional features include in-built fuel tanks, which provide customers with fuel autonomy in excess of 30 hours at 75% load, saving on refuelling frequency, associated costs and emissions. Running costs are further reduced through an extended oil change period of 500 hours.
The new sets have been added to the range that includes the X 3.3 model rated 30 to 38kVA at 50 Hz and 27 to 35 kW at 60 Hz.
