Oil Mist Detector
Schaller Automation GmbH & Co. KG

The VISATRON VN215/93 Oil Mist Detector (OMD) is one of the most widely recognized marine engine safety systems used onboard commercial vessels and power generation installations. Manufactured by Schaller Automation, the VN215/93 is specifically designed to monitor crankcase oil mist concentrations and provide early warning of dangerous conditions that could lead to crankcase explosions and severe engine damage.
The primary purpose of the VISATRON VN215/93 is to continuously sample air from individual crankcase compartments and detect abnormal oil mist generation caused by overheating bearings, piston failures, lubrication issues, mechanical friction, or other developing engine faults. When excessive oil mist is detected, the system activates alarms and protective actions, allowing engineers to investigate the problem before catastrophic damage occurs.
For ship operators, this equipment plays a critical role in engine room safety, crew protection, machinery reliability, and regulatory compliance. The VN215/93 is widely installed on slow-speed and medium-speed marine diesel engines operating on container ships, bulk carriers, tankers, LNG carriers, LPG carriers, offshore vessels, and other commercial vessels worldwide.
SM MARINE SERVICE™ supplies New, Used, and Reconditioned VISATRON VN215/93 units along with spare parts, repair services, troubleshooting support, calibration, and worldwide delivery solutions.
The VISATRON VN215/93 belongs to the VISATRON VN93 series of Oil Mist Detectors developed by Schaller Automation. Unlike simpler oil mist monitoring systems, the VN215/93 uses an individual compartment suction pipe arrangement that enables identification of the specific crankcase compartment with the highest oil mist concentration. This significantly reduces troubleshooting time during alarm conditions.
The system continuously extracts crankcase atmosphere through a wear-free suction system and analyzes the opacity of the sampled air using an optical measuring track. By monitoring oil mist concentration in real time, the detector can identify abnormal conditions long before an explosion hazard develops.
The VISATRON VN215/93 is particularly suitable for large crosshead marine diesel engines where oil mist may spread slowly from the damaged compartment. The detector's high sensitivity allows accurate localization of potential failures, helping engineers take corrective action before major machinery damage occurs.
The complete system generally consists of:
One of the most important features of the VN215/93 is its ability to identify the specific compartment with the highest oil mist concentration. This enables rapid fault localization and significantly reduces engine troubleshooting time.
The VN215/93 offers the highest sensitivity within the VN93 product family. It is specifically engineered for medium-speed and slow-speed crosshead engines where early detection of oil mist is critical.
Unlike passive monitoring systems, the VISATRON VN215/93 continuously extracts crankcase atmosphere using a suction system. This active monitoring method improves response times and enhances safety performance.
The system measures oil mist concentration using an optical opacity measurement principle. This proven technology provides reliable detection of dangerous oil mist accumulation inside engine crankcases.
The detector provides Oil Mist Alarm outputs, Pre-Alarm outputs, and Ready signals, allowing direct integration with engine safety systems and ship automation platforms.
Special suction funnels, drainage arrangements, and integrated heating elements help prevent false alarms caused by splash oil, water condensation, and vessel motion.
