critical power

Aggreko has entered a four-year deal with Cirque de Soleil to provide power and temperature control for the show on tour.

Cirque de Soleil has five touring shows that travel across the USA, Canada, Central and South America, Europe and Asia. Aggreko will need to provide machinery that can operate in the extreme weathers presented on all continents.

The power for each show must be uninterruptible and independent from the local electricity grid. Aggreko has provided power to many entertainment events worldwide including the 2012 London Olympic and Paralympic Games.

Cummins has brought out mobile generator units that are the first in the industry to comply with Tier 4 final emissions levels without using a diesel particle filter (DPF).

The units, ranging from 150 kW to 275 kW, will be available from 2014. They are among the first required to comply with the emissions regulations for 175 to 751 HP.

The Tier 4 Final regulations limit mobile generator set emissions to 0.4 grams per kWh of nitrogen oxides (NOx) and 0.02 grams per kWh of particulate matter - soot. This is a 90% reduction on the previous regulations introduced in 2005.

Cummins made improvements to its in-cylinder engine, exhaust gas recirculation and selective catalytic reduction exhaust after treatment.

The efficiency of the in-cylinder combustion engine means no DPF is required.

"By avoiding the need for a DPF, we were able to simplify the after treatment package with benefits of lower maintenance for rental operators. An added advantage to in-cylinder combustion improvement is reduced fuel consumption for end users," said Santhosh Sorab, marketing manager for Tier4 Final Product Development of Cummins Power Generation.

The first Tier 4 Final generator sets for the rental market from Cummins Power Generation will be the C150D2R generator set, standby rated at 150 kW, and the C200D2R generator set, standby rated at 200 kW. Both units will be available for delivery by Q3 2014. The C275D2R generator set, standby rated at 275 kW, is scheduled to be available beginning in Q4, 2014.

The Tier 4 Final certified mobile generators will feature switchable 60/50Hz dual frequency operation with multiple voltage configurations of 208V, 240V and 480V in three-phase, and 240V in single-phase. The units will also feature the new PowerCommand 3.3 controller (PCC) with both paralleling and advanced master-less load demand capabilities.

The packaged generators will also include a diesel exhaust fluid (DEF) tank and monitoring unit that controls the dispensing of DEF into the SCR to cut emissions of NOx. The normal consumption of DEF is less than 4 percent of fuel consumption, and the DEF reservoir and the fuel tank are sized appropriately to ensure uninterrupted 24-hour runtime.

General Electric has launched a turnkey power system module that can be used to expand existing data centres or to provide new and temporary capacity to companies requiring data centre services.

The PowerMOD can be configured with a range of electrical components including automatic transfer switches, switchboards, UPSs and transformers.

The modular containers are available to provide between 200kW to 1500kW back up power and can be commissioned within five months. GE believes this quick deployment will appeal to customers requiring a faster solution than a traditionally built data centre, as well as offering capital savings.

The PowerMOD unit can be cooled with free cooling (via an economiser), direct expansion, chilled water or evaporative cooling.

Doosan Portable Power has developed a range of technologies that allow engines to operate in extreme cold temperatures. The Webasto engine pre-heat system will be available as an optional extra with all Doosan generators.

The system, which can be integrated to any engine, includes a fuel operated coolant heater that can be remotely operated with a timer that controls the engine pre-heating system that can be programmed for seven days.

The timer feature will improve on-site productivity by having engines warmed and ready to provide power at a designated time. This  reduces fuel consumption and engine wear in waiting for the machine to start up.

Another feature of the pre-heat system is the Arctic Fox fuel warmer that prevents diesel from gelling in very cold temperatures and will allow any Doosan generator to be used efficiently on very cold sites.

Hitec Power Protection has appointed a new Chief Executive Officer called Ivo Mönnink to bring Hitec into new markets and expand the company’s global presence.

Hitec has close to 1700 UPS units installed worldwide including the Diesel Rotary UPS System, called the Hitec QPS, which is built to reduce plant space with the highest power density per square meter in the industry. 

Mönnink has been brought in to continue this technology leadership. "Hitec doesn't just manufacture and sell dynamic uninterruptible power supplies -- they invented them. For more than 50 years, the company has produced the market's most advanced solutions for keeping mission-critical infrastructures reliable and running at peak efficiency," said Mönnink.

Prior to Hitec, Mönnink worked at Netherlands-based FERM B.V, a power equipment provider; he was Europe Managing Director at Chicago-based Pregis Hexacomb, a packaging company. He also brings commercial, branding and communications expertise to Hitec from roles at Nike and Unilever.
