Schaller Visatron VN115/87plus Oil Mist Detector

Description

The Schaller Visatron VN115/87plus oil mist detector UAE (Art.No. 11651) is a world-renowned marine diesel engine safety system from Schaller Automation Germany — protecting over 54,000 engines worldwide against catastrophic oil mist explosions in the crankcase.

This Schaller Visatron VN115/87plus oil mist detector continuously monitors the atmosphere inside marine diesel engine crankcases using infrared opacity measurement. When oil mist concentration exceeds the set alarm threshold — indicating dangerously hot or failing bearing surfaces — the system immediately triggers an alarm to the ship’s safety system, initiating engine slowdown or automatic shutdown to prevent explosion, fire and catastrophic engine damage.
