Schaller Automation – Oil Mist Detection Systems for Ship Engines and Machinery. Schaller has been developing, producing and selling safety systems for large diesel, gas and dual-fuel engines in the shipping for more than 60 years. These safety systems, called Oil Mist detection Systems (OMD), are successfully in operation aboard ships and power stations around the world. More than 55,000 engines are safely protected by the VISATRON systems. Their daily mission is the detection of hazardous operating conditions where damage to bearings can lead to the escape of hazardous oil mist. This oil mist contains minute oil particles and can, in extreme cases, lead to an explosion within the engine crankcase. Schaller represents a reliable safeguard against such accidents. The company is working on the development of highly sensitive intelligent monitoring systems for early detection of a beginning damage, even early enough to prevent the formation of oil mist before it start.
