Tier 4-Final mtu Engines Power Growing Oil-Free Air Compressor Fleet

“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).

“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.
