Genset suppliers you should know
A round-up of major suppliers and players
Gensets are used to supply electrical power in places where utility power is unavailable, or where power is needed only temporarily.
Action’s fleet of gensets vary according to the size of the project, and the power required. The biggest demand from the company at the moment is units between 500 kVA and 1 250 kVA. Some of these run separately, while others are connected to each other, thereby creating a small power station. At present the bulk of Action’s business is derived from Dubai, but the company is also serving Abu Dhabi from its office and yard in Mafraq.
Aggreko can supply generators from 15 kVA to 2 000 kVA in single units, as well as multi-megawatt packages using 1 250 kVA units linked together. Smaller sets are used to power Portacabins, piling machines and hand tools, while construction cranes are usually powered by 250 kVA or 320 kVA generators. Large-scale construction projects often require multi-megawatt power packages to power labour camps.
Altas Copco provides portable and stationary generators. The company has reported increased activity in the larger 500 kVA to 1 000 kVA category due to power shortfalls in some urban areas, but it mainly supplies contractors who require units in the 20 kVA to 275 kVA range. The company believes there is a trend towards buying as opposed to renting, as only 25% to 30% of generators sold go to rental companies.
Cummins Inc., a global power leader, is a corporation of complementary business units that design, manufacture, distribute and service engines and related technologies, including fuel systems, controls, air-handling, filtration, emission solutions and electrical power generation systems.
Headquartered in Columbus, Indiana in the US, Cummins serves customers in more than 160 countries through its global network of 550 company-owned and independent distributor facilities, and more than 5 000 dealer locations. Cummins reported net income of US$755 million on sales of US$14.34 billion in 2008.
Cummins Middle East FZE, the first wholly-owned dependant distribution entity of Cummins Inc. in the region, was established in early 2000 in order to strengthen its distribution network’s reach and better support the increasing engine population in the area.
It is headquartered in the Jebel Ali Free Zone in Dubai, and is responsible for the UAE, Bahrain, Yemen, Qatar, Jordan, Oman, Afghanistan, Lebanon and Iraq.
FG Wilson designs and manufactures diesel and gas gensets. Its most popular products for construction sites range from 60 kVA to 500 kVA. It also gensets from 10 kVA to 2 200 kVA so as to be able to cater for customer demand. All these can be supplied as sound-attenuated and weatherproof canopied gensets. FG Wilson offers technical support from pre-sales and aftersales support from installation to commissioning. Its Middle East business includes Iraq and Afghanistan.
Founded in 1982, Himoinsa is a manufacturer of gensets based in Spain. It has suppliers across the world, including the Middle East, which distributes its products and supplies spare parts. The products found most popular on construction sites are Himoinsa’s 100 kVA to 500 kVA units.
Ingersoll Rand supplies 20 kVA to 600 kVA diesel gensets. Its business comes from almost all sectors that require electrical power. Business fluctuates from one sector to another depending on the general economy. For example, the construction industry has traditionally lead growth in the GCC.
However, the slowdown due to the global economic crisis has lead to a resurgence in renting as the preferred method of acquiring gensets for the construction sector.
Kirloskar’s 250 kVA genset is widely used at construction sites to power Portacabins, labour camps and various other equipment and accessories required on-site. Over 50 000 Kirloskar green gensets are manufactured annually, and all are ISO 9001/9002 accredited. Kirloskar Middle East FZE is located in Ajman, from where it supports the entire region. Kirloskar has a substantial share and a presence in the engine and diesel genset segment in the GCC.
Manlift Group distributes a large fleet of gensets built specifically for harsh conditions and extreme temperatures. These feature large internal fuel tanks for 24 hour operation. They range from 30 kVA to 1 250 kVA. The company supplies the UAE and Qatar, and has worked on the Dubai Metro, Palm Jumeirah, Dubai Festival City, Motor City, Al Raha Beach and Yas Island.
CAT genset for CHP applications
Caterpillar has announced the availability of the G3512E advanced natural-gas-fuelled genset, designed for maximum efficiency in extended-duty distributed generation and combined heat and power (CHP) applications.
Driven by a Cat electronically-controlled, lean-burn gaseous-fueled reciprocating engine, the G3512E genset has been designed to offer a high power density and excellent fuel efficiency, while maintaining tight NOx control. It provides flexibility to operate on pipeline natural gas with a wide range of methane numbers without sacrificing efficiency and performance, and delivers up to 41.7% ISO electrical efficiency without water pumps.
The Cat G3512E genset operates at 50 Hz/1500 rpm with the Miller combustion cycle, is rated at 1 000 ekW, and has a standard NOx emissions rating of 500 mg/NM3 at a separate circuit aftercooler (SCAC) inlet water temperature of 54˚C. It is built on a heavy-duty, diesel-based platform and uses an advanced camshaft and turbocharger design to achieve high mechanical efficiency. It additionally features an open combustion chamber design, which allows for a low-pressure fuel system of 10 to 35 kPa.
A standard feature is a digital microprocessor gas engine control module that automatically and precisely regulates ignition, engine governing and air/fuel ratio for optimum fuel economy and stringent NOx control. Its patent-pending air/fuel ratio control monitors charge air density and maintains NOx within tight tolerances under a variety of ambient and load conditions.
It features an individual-cylinder detonation sensing and timing control, with a prechamber-type spark plug design for extended service life without adjustment. Additional functionality includes an emergency stop fuel-purge cycle and programmable protective relaying functions.
The genset is easily tailored to specific applications. Additional features include exhaust options, alarm and remote annunciator modules and battery chargers. It is also available with an optional 250 mg/NM3 NOx emissions setting and 54˚C SCAC temperature rating.
