Protecting your engine, extending oil life
Diesel engines face tough conditions - and so does their lube oil. During operation, the oil is constantly exposed to contaminants like dust, metal particles, water and chemical residues. These impurities speed up oil aging and can lead to increased wear and reduced engine performance.
Trunk piston diesel engines are especially vulnerable. Under partial load, unburned fuel and combustion residues can enter the crankcase. When these mix with water vapor, they form acidic compounds that can damage critical components such as bearings, pistons and cylinders.
The importance of effective lube oil treatment
Contaminated lube oil leads to increased wear, reduced engine efficiency and costly downtime. Regular and efficient treatment of lube oil is essential to:
- Remove solid and liquid contaminants
- Prevent corrosion and premature engine wear
- Extend the service life of both oil and engine components
- Reduce maintenance costs and environmental impact
Maximum engine protection with minimal effort
Centrifugal separation is the most effective and widely used method for lube oil treatment. In this process, a separator is installed in a bypass loop within the engine’s lube oil system. The separator efficiently removes water, sludge and particulate matter, ensuring the oil remains clean and fit for use.
For applications requiring 24-hour unattended operation, self-cleaning mineral oil centrifuges are the preferred choice. These systems automatically discharge separated contaminants, minimizing manual intervention and maximizing uptime.

Centrifugal Separator
GEA separators are designed for liquid-based applications. Using centrifugal force, they are used for separating suspensions consisting of two or more phases of different densities, i.e. they can be used for liquid-liquid separation, for liquid-liquid-solid separation or for liquid-solid separation. They are equally as effective at separating liq...
Machine automation & control
Every plant or machine, which is designed for a reliable long-term operation, requires a control unit that enables the communication between the different system parts. It is one of the most important component that guarantees reliability and efficient operation.

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
