The operator panel incorporates logical and simple operator controls and clear status indicators. Users of the 2100 will benefit from having text on the panel fascia presented in a multitude of different languages.
The LEDs are colour coded and all values are expressed as a percentage of nominal rated values. An ‘out-of-limits’ condition will see the bar graph move from green to yellow and, depending on how critical the condition is, into red. Another feature is the menu-driven graphical display panel. The nine-line display, accommodating 27 characters per line, can support different languages including character-based languages. Gensets utilizing the control are scheduled to start production in 2003.
Wärtsilä hails Vacon as supplier of the year
Wärtsilä has chosen Vacon Plc as its ‘Supplier of the Year 2002’. Vacon manufactures frequency converters, which are increasingly used to control and regulate the radiator coolers in Wärtsilä power plants.
Vacon has systematically developed its quality and environmental management systems and implemented European Foundation of Quality Management (EFQM) self-assessment methods.
Nacon’s latest product, the NX Series frequency converter, is especially suitable for Wärtsilä’s global strategy.
Frequency converters lower total power plant costs
Frequency converters lower total power plant costs due to the considerably reduced need for cabling, and the fact that low-voltage equipment requires fewer cable outlets. This mechanism is useful for standardization, because it offers a larger regulating range for standard solutions. Engine cooling is more uniform than when regulated by mechanical thermostats. Noise levels of power plant radiators are minimized with the use of frequency converters, as the radiator’s automatic rotating speed is reduced.
Volvo supplies engines to China
Swedish-based engine manufacturer Volvo Penta has teamed up with its Chinese partner, Wuxi Diesel Engine Works and supplied diesel engines as China’s infrastructure boom hots up.
One of the 60 diesel engines bound for China
Volvo Penta has received orders for a total of 60 diesel engines for different types of mobile concrete pumps. The customers are Shanghai HongDeLi and XuZhou Tiand Construction Machinery, which are both Chinese manufacturers of construction equipment.
The working relationship between the two companies dates back to 1995. The continuous flow of investments in China has led to new roads, tunnels, bridges and buildings, giving the engineering sector a boost. This has led to Volvo Penta capitalizing on its industrial engine operations in the country. These products are used to pump concrete – with the largest models capable of pumping 85 m3/h through pipes up to 1200 m long.
Cummins shows latest generator range
Cummins Power Generation launched its Eurospex range of electrical generators earlier this year.
The genset range can deliver between 30 and 500 kVA and is targetted at the European market.
The three key ideas that were decisive in the conception of the commercial strategy, said Cummins, were the reduction in production costs due to the decentralization of some of the factories; the marketing of a standard product with a minimum of available options; and immediate availability.
Kenda wins Enel contract

In addition to a Kenda Operational Metering Summator (OMS), the panel will include five flow ..computers, a rack-mounted local collector station (LCS) running Kenda’s MDCS software, and a meter processor with dual RS485 Modbus outputs.
The OMS unit is designed to produce real-time data for the trading systems now used by generating companies as part of the UK’s New Electricity Trading Arrangements.
The meter processor will take the real-time data from the OMS, together with half hour demand values from the LCS, and make the data available to the plant’s distributed control system.
Wärtsilä supplies power modules to Caribbean
Wärtsilä has won a contract to supply two power modules to the island of Vieques, near Puerto Rico. The customer and contractor is Puerto Rican company RG Engineering, and the end user will be Prepa – the second largest publicly-owned US utility.
This crucial power plant, in a region prone to hurricanes, will be a reliable power source in case of emergency for the island of Vieques, which is located off the Puerto Rican eastern shore. Prepa requested that the power plant could run baseload if needed.
The 18V200 diesel engine generator
The power module is designed to allow for easy plant operation and maintenance in continuous use conditions and the modular nature of the plant will enable it to readily accept a third unit. Wärtsilä’s versatility and understanding of customer’s needs, allowed the team to provide a bid that was both competitively priced and fully compliant to Prepa’s demanding technical requirements.
Each of the two power modules is a pre-assembled, self-contained unit containing a 3.3 MW, 18V200 diesel generator set and auxiliaries. Together with the electrical module containing the control room and the medium voltage sub-station, this forms a complete power plant that can be installed o.r relocated in a very short time.
Wärtsilä’s part of the contract will include equipment delivery, installation supervision and commissioning, while RG Engineering will perform the balance of the project, which entails site preparation works, fuel storage, high voltage substation and transmission lines.
New power station in Yemen
Man B&W Diesel Canada has completed commissioning of the new power station for Nexen’s Masila Block processing facility located in Yemen.
Yemen’s new power station
The facility is powered by twelve 16 RK270 engines built by MAN B&W. The diesel engines can produce 4.4 MW at ISO rating, running at 900 r/min. The station will generate 40 MW power.
The RK270 genset package was chosen for its unique combination of fuel consumption, reliability, low capital cost and the Canadian group’s expertise in power plant engineering.
The location of the site, which is situated 190 km inland from the Port of Mukalla and can only be reached by steep mountain-pass roads, demanded precise organization.
Canadian Nexen Petroleum Yemen is the largest oil and gas producer in Yemen.
Tiscali selects Ingram, SDMO to optimize backup power
Tiscali UK, a subsidiary of Tiscali, the internet service provider (ISP), has chosen Ingrams Installation and SDMO Energy to provide the ISP with power backup for its newly built communications site in Milton Keynes, UK.
Ingrams Installations and SDMO Energy secured the project to supply two SDMO XS 2250 SK generators, with all associated equipment, to be installed in the client’s existing generator hall.

Cummins supplies gensets to Italian hospital
Cummins distributor Cummins Diesel Italia has just completed an installation in the Hospital Maggiore in Milan of two 1120 DFLC gensets.
Two of the 1120 DFLC gensets at Milan’s Maggiore Hospital in Italy.
Both gensets serve as emergency standby sets in one of the five electricity supply areas of the hospital. In the event of a grid failure, staff have set up the operating mode to ensure that one stand-by set provides immediate backup power. If more power is required, or if the first set is undergoing routine maintenance, the second backup set begins operation.
The gensets are installed in two adjacent rooms and are both located inside canopies for sound insulation. Cummins Diesel Italia (CDI) assembled these canopies on site.
Waukesha adds features to VGF engine line
Waukesha Engine has announced the introduction of the new extender package to its popular VGF engine line.
The extender package offers internal enhancements which increase the engine’s durability and longevity expectations, as well as external improvements that lengthen service intervals and make maintenance easier.
New capabilities have been added to the VGF engine
According to Tim Baker, VGF Product Manager: “The extender package now offers VGF users the performance features of a high-speed product with the durability of a medium-speed engine. Field testing has proven that extender VGF engines give the user features and benefits far beyond what is currently available from competitive engine manufacturers.”
The most visible feature of the package is the oil pan that has twice the capacity of the previous pan. Besides lengthening the period between oil changes, the pan has access panels to allow servicing of major engine components (oil pump, main and rod bearings) without having to be removed. The wider, heavier pan also reduces vibration and serves as a base for the 6- and 8-cylinder engines.
Reliability advancements were also made to the engine’s top end that include:
- Valve train lubrication to reduce wear
- Polished chrome stem valves to reduce guide wear and promote longer life
- Closed breather system element with integral vacuum regulator to maintain negative crankcase pressure to prevent oil leaks.
Cummins targets fuel goals
The dual goals of increased fuel efficiency and decreased environmental impact are two main drivers in the design of electricity generation based on diesel or gas reciprocating engines.
In response to new emissions reduction mandates, Cummins has developed engines that have lower emissions and are more fuel-efficient than previous designs. Its range of diesel engines for stationary and mobile off-road use meet control standards having reduced NOx by 54 per cent over. To meet future standards, a number of emission strategies are currently being applied namely exhaust gas recirculation (EGR) and selective catalytic reduction among others.
An example of the new type of diesel genset production from Cummins Power Generation is its 2 MW QSK60. It features electronic controls, increased fuel injection pressures, improved combustion chamber geometry, and turbochargers with after-coolers to improve fuel efficiency and reduce NOx and PM emissions.
