Engine power

Whether an engine power plant is small back-up facility or a plant that generates hundreds of megawatts, one wants to get the most from it. Doing so depends on the diesel engine or engines at its heart, but also on the surrounding equipment. Alfa Laval is a leading supplier of auxiliaries with a long history of serving engine power businesses, which means we understand the full scope of needs. Based on the plant’s unique setup and conditions, we can help in optimizing its energy production.

Alfa Laval at engine power plants

Alfa Laval equipment contributes to nearly all aspects of engine power plant operation, delivering high performance with low cost of ownership.

Ideal for new plants, it can also be installed in existing plants as replacements and upgrades for major gains in efficiency.

Using our solutions and knowledge can improve reliability, sustainability and more – including bottom-line performance.


Fuel and lube oil cleaning

Centrifugal separation is the most reliable and cost-effective means of purifying fuel and lube oil. Alfa Laval’s high-speed separators build on more than 100 years of separation experience, combining high separation efficiency and engine protection with true ease of use.
