Cummins gensets receive EPA Tier 4 Final certification

US Environmental Protection Agency (EPA) has given Cummins’s new line of diesel backup power gensets a Tier 4 Final certification.

EPA approved the complete line of high-horsepower gensets, ranging from 680kW to 2750kW. The generators are mainly used for backup power in critical power applications such as hospitals and data centres. The line is also designed for standby power applications where air quality is impaired and for emergency use.

Cummins said it is the first manufacturer receiving a Tier 4 Final certification. “We are proud to be the first company to be awarded Tier 4 Final certification for our generators,” said Dennis Heathfield, executive director at Cummins.

The Tier 4 Final generators achieve a 99% reduction in particulate matter emissions in comparison to Tier 2 products. “By achieving this emission reduction, we are providing customers with more fuel-efficient and cleaner generators,” added Heathfield.

EPA adopted Tier 4 emission standards in 2004 for new off-road diesel engines in order to reduce hydrocarbons, carbon monoxide, particulate matter and nitrogen oxide. Tier 4 Final standards require a reduction to near-zero levels.

Wärtsilä to supply 225 MW power plant to Texas utility

Thu, 01/10/2013 - 17:36 -- Ruth Williams

Finnish gas engine manufacturer Wärtsilä is to engineer and supply a 225 MW power plant to South Texas Electric Cooperative (STEC) in the USA.

The STEC Red Gate power plant will be located in Hidalgo County, Texas and is scheduled to be in commercial operation by summer 2014. The plant will be powered by 12 Wärtsilä 50SG engines running on natural gas.

The new Red Gate power plant is designed to meet BACT (Best Available Control Technology) pollution standards as mandated by the United States Clean Air Act.  Wärtsilä  said one of the benefits of the 50SG engine is that its high simple-cycle efficiency is achieved with minimal water consumption.

Wärtsilä has also signed a maintenance agreement to provide technical and operational assistance with maintenance planning, technical advisors, spare parts, and an on-site inventory.

Lead-acid growth for Hitachi

Wed, 08/15/2012 - 18:02 -- Ruth Williams

Hitachi Chemical Co will increase its production capacity for industrial lead-acid batteries by next January by expanding facilities of the subsidiary company Shin-Kobe Electric Machinery Co.

Some US$12 750000 (one billion yen) will be spent on constructing a building with a new assembly line at Shin-Kobe's Nabari Works in Mie Prefecture, the main site making lead-acid batteries.  It is estimated cell production capacity is likely to increase by 50%.

The site will make back-up power source batteries, the LL-W series of which demand is growing for in offices and factories at risk of power failures.  Joining 192 LL-W batteries together can produce 40kw of electricity for around ten hours.

Shin-Kobe Co. accounts for roughly 30% of the domestic market for industrial lead-acid batteries.  The LL-W products claim a battery life of 17 years, one of the world's longest, and are a fraction of the cost of a lithium-ion counterpart.
