Spanish genset manufacturer Himoinsa is to deliver seven of 36 gensets purchased by Railways Infrastructure Instalaciones y Servicios to supply power along several stretches of the 444 km Mecca to Medina high-speed rail construction project in Saudi Arabia. The delivery is scheduled for the coming weeks.

The manufacturer’s generator sets for desert climates were designed with tropicalised radiators with double varnish and anti-condensation heaters. The alternator air filters are treated to prevent dust from entering and to ensure uninterrupted power supply, Himoinsa said.

‘We are prepared to work in the extreme conditions of the Middle East; being able to withstand the daytime temperatures of 50ÂșC is essential’, said Keith Webb, general manager of Himoinsa Middle East.

‘Equipment for desert areas demands special attention. Apart from the heat, other factors such as humidity can cause problems if not given due consideration, while dust is also a factor that can clog filters and accumulate in the mechanisms and affect performance,’ he added.

This month Himoinsa announced the 10-year anniversary of its Middle East business, where it has recently opened new facilities in the UAE.

MTU genset to be tested on harbour tug

MTU genset

Rolls-Royce’s MTU and Fairplay Towage are to test an MTU diesel genset with SCR exhaust aftertreatment on a harbour tug in order to verify compliance with IMO Tier III emission requirements that come into force as of 2016.

According to Rolls-Royce, nitrogen oxide (NOx) emissions will be cut by 90% compared with the IMO Tier I regulation introduced in 2000.

‘This is one of the world’s first tests of high-speed diesel engines equipped with an SCR system designed to meet the NOx levels required by IMO Tier III,’ said Dr Michael Haidinger, chief sales officer of Rolls-Royce Power Systems.

The new Fairplay tug with a bollard pull of 90 tonnes is currently being built at the Astilleros Armon shipyard in Spain, and is scheduled to go into service in the Port of Rotterdam in 2015.

Along with the two main 16V 4000 M63L propulsion engines, MTU will supply a 16-cylinder 4000 M23F diesel genset rated at 1520 kW, and the SCR system designed to provide minimal emissions in urban areas. The exhaust aftertreatment system, with selective catalytic reduction (SCR) technology, is connected to the genset.

The tests on the tug are planned to run continuously for 10,000 hours.

Cummins to introduce new gensets


Generator set maker Cummins Power Generation is to host a series of virtual events to present the firm’s next-generation gensets.

The events will take place via webcast in a virtual environment and will feature presentations by Rich Freeland, president and CEO of Cummins Inc, and other senior executives, the firm said.

The events will include an online exhibition and resource centre allowing attendees to view interactive models of the new gensets as well as download technical data and application information.

Scheduled for viewing in US, Asian and European time zones, the events will take place on 5 and 6 November.

Diesel genset market to reach almost $20bn by 2019


The global market for diesel gensets is projected to reach US$19.9 billion by 2019, according to a new report from analysis firm TechSci Research.

The report, Global Diesel Genset Market Forecast & Opportunities, 2019, found that low power rating diesel gensets make up the largest revenue-generating segment in the global market due to their high-volume use in the commercial, manufacturing, power utility, telecom, data centre, mining and petrochemical industries. However, the very high power genset segment is expected to see the fastest growth during the forecast period.

The report found that the global market for diesel gensets is largely dominated by the Asia-Pacific region due to its rapid urbanisation and industrialisation, with China and India emerging as the largest revenue-contributing countries for diesel gensets. During the forecast period, the report found, the Middle East/African and South American regions are expected to grow at the fastest rate, driven by strong market growth in countries such as Brazil, Argentina, Saudi Arabia and the UAE.

In addition to rising worldwide power demand and poor or unreliable power delivery infrastructure, the report pointed to growing demand for mobile and biofuel-based diesel gensets as factors that will continue to benefit the market segment.

Atlas Copco launches QAS 25

Atlas Copco

Sweden’s Atlas Copco Portable Energy has announced the release of its new QAS 25 generator set, equipped with an Isuzu 4LE engine and a Diesel Oxidation Catalyst (DOC) to achieve Tier 4 Final emission levels. The QAS 25 can be used for prime or standby power, Atlas said, and features a 72-gallon fuel tank for a 45-hour run time. It is mounted on a durable frame and surrounded by a galvanneal steel enclosure, and is powder coated for a scratch- and corrosion-resistant surface.

The QAS 25’s enclosure is sound-attenuated and has a vertical radiator and exhaust discharge to ensure low dBA levels for use on noise-sensitive job sites, residential areas or events. Its voltage selector switch allows operators to adjust the machine’s output to 480 and 208/240 V three-phase settings as well as 120/240 V single phase.

The genset’s DOC after-treatment device requires no regeneration or maintenance, the company says, while the engine meets Tier 4 Final emissions without the need for diesel exhaust fluid or a diesel particulate filter system. Engine fluids are plumbed to the edge of the skid to eliminate the hassle of maneuvering pans into the interior space. The standard spillage free base-frame is sized to contain 110% of the machine’s fluids and fuel, safeguarding the site and protecting the environment, Atlas says.

The QAS 25 comes equipped with an optional trailer with robust tie-downs for transport on a flatbed. Skid units contain fork pockets for forklift transfer. All units come with a standard single-point lifting eye in the enclosure for maneuvering with a crane.
