Easy being green
As pressure intensifies for industries around the world to reduce emissions and improve air quality, Aggreko took a sustainable approach to re-fleet its oil-free air (OFA) compressors. Oil-free air prevents contamination of pneumatic systems and the production of unsafe environmental condensate at a site. Aggreko’s electric OFA compressors have also been a popular option to reduce emissions. But in places where access to the electrical grid isn’t readily available customers will need to provide their own power source. This is where an end-user can opt to rent Aggreko’s diesel-powered OFA compressor.

With the help of mtu’s 617 bhp 6R 1500 diesel engine, Aggreko offers its customers a brand-new line of EPA-certified Tier 4 final diesel OFA compressors. The units deliver oil-free air at pressures up to 150 psig with flowrates up to 1,600 cfm. Each compressor is outfitted with Aggreko Remote Monitoring equipment, allowing experienced engineers and technicians to monitor performance around the clock.

Aggreko offers its customers a brand-new line of EPA-certified Tier 4 final diesel OFA compressors.

“mtu’s reputation and performance is very good,” said Fernando Arce-Larreta, head of OFA for Aggreko. “We’re using mtu engines on every new tier 4 final oil-free air diesel compressor in the field.”

Aggreko selected mtu engines because of three key differentiators: fuel efficiency, which results in lower costs for Aggreko’s end-users; emissions compliance; and reliability. 

The mtu difference
In addition to meeting EPA Tier 4 emissions standards, the mtu 6R 1500 diesel engine meets California Air Resources Board (CARB) and EU Stage IV non-road emissions regulations. Using advanced technologies, such as selective catalytic reduction (SCR) to convert pollutants into harmless vapor, and cooled exhaust gas recirculation (EGR) to reduce combustion temperature and lower NOx emissions, the engine achieves decreased environmental impact and reduced fuel consumption— and since these engines do not require a diesel particulate filter (DPF) to attain EPA/CARB emission standards, no regeneration is required, a powerful and winning combination for business. And the engine reduces particulate emissions through internal processes, eliminating the need for complicated diesel particulate filters (DPF).

In addition to meeting EPA Tier 4 emissions standards, the mtu 6R 1500 diesel engine meets California Air Resources Board (CARB) and EU Stage IV non-road emissions regulations.

“Aggreko is very happy with the mtu technology. Being Tier 4 compliant has greatly helped increase our presence with customers that have a need for this technology,” said Arce-Larreta. “Our compressors offer unmatched reliability and performance, which is a key differentiator for us.”

In side-by-side trials of its mtu-powered units, Aggreko found that its OFA compressor saved 10 percent in fuel cost over competing products. For end-users who run air compressors 24 hours a day, seven days a week, this provides significant cost savings. 

Poised for growth
The use of the mtu 6R 1500 engine allows Aggreko to offer its customers an industry-leading solution that provides the performance, reliability and emissions requirements they demand, saving them money and ensuring invaluable uptime. Stewart & Stevenson, an mtu authorized distributor, supports Aggreko with quality spare parts and local service, proving a complete package for customers. 

“Aggreko is an exciting customer for mtu,” said Jorge Kusaka, senior sales manager, construction, industrial & agriculture engines, mtu America. “From power output to footprint, mtu engines are well-matched to an air compressor application. We look forward to growing in this space with our new partner.”

Aggreko has a built a strong OFA compressor rental fleet to support refineries, manufacturing facilities (e.g., paper mills, electronics, food and beverage, etc.) and other industries that require oil-free air for their operation.

Logging in the dense forests of Washington’s Olympic Peninsula is challenging work. Steep mountainous terrain and twisting gravel roads make a logging truck’s daily commute long and treacherous. It rains more than 200 days of the year, dumping 10 to 12 feet of rainfall. Brisk winds from the nearby Pacific Coast add another degree of difficulty. Despite all these obstacles, Dahlgren Logging Inc. has harvested timber here in the mountains and canyons for nearly 60 years.

Power. Passion. Partnership. mtu engines help Claas tractors break records at Nebraska Tractor Test Laboratory Before a new tractor model is ready to work the land, it must face the oval test track at the Nebraska Tractor Test Laboratory. The facility opened in Lincoln, Nebraska nearly a century ago. Back then, horses were commonly used to plow and harvest—not tractors. Early models often failed to perform as advertised. In 1919, the Nebraska Tractor Test Law required manufacturers to verify horsepower claims before a tractor is offered for sale in the state. The first tractor test was conducted in 1920, with a model that produced a mere 15 horsepower. Since then, more than 2,000 tractor models have been tested, including modern 500 hp models.
