Our solutions

The objective of our solutions is to prevent damage to engines and systems which can be caused by the formation of oil mist. Our oil mist detectors protect large diesel, gas and dual fuel engines in a variety of different areas of application. Our unique software detects load reversals and changing wear conditions so no false alarms are triggered, ensuring maximum reliability. Only Schaller can do that! Our Visatron series contains the experience from over 55,000 installed systems for oil mist detection.

Schaller oil mist detectors immediately identify the sources of hazardous oil mist and provide a corresponding notification. Our Visatron product family features the following convincing strengths:

  • Low-maintenance oil mist detectors for the complete life cycle of an engine, without complicated maintenance
  • Maximum reliability against False alarms – even under changing power loads of the engine
  • Meets all common vibration standards of the classification societies
  • Ideal for monitoring large engines

Benefits across industries


Being close to our customers is very important to us. We therefore rely on a worldwide network of partners who help us to provide fast and proactive support for our customers. With the same standards for quality and reliability!

Offshore and at sea

Not only are heavy-duty ship diesel engines, power generators on oil rigs and engines in many other applications subject to special strains and regulations, they can also only be repaired at great expense. Oil mist explosions on engines have occurred repeatedly in recent years. Oil mist detectors from Schaller Automation have the task of preventing this.

Power engineering

Power generation is one of the essential infrastructure components of any country. People’s lives depend on the continuous supply of power, and not only in hospitals. It is therefore vital to protect power generators against damage. The products from our Visatron series detect oil mist and act before damage can occur.
