Why use of oil mist detector
Oil Mist Detectors protect large Diesel, Gas and Dual Fuel engines of all applications from heavy consequential damage
due to oil mist explosions as a result of overheating of bearings or other moving parts.
All Schaller VISATRON Oil Mist Detection Systems continuously draw the atmosphere from every compartment of the
engine’s crankcase by the use of a suction system. The suction vacuum required is generated by a wear-free air jet pump
within the device, fed by compressed air.
The basics- and advantages of our Oil Mist Detectors
Although different to other systems on the market, this
technology is well proven and accepted by both,
engine makers and ship owners and brings along
some field advantages such as high operations
reliability and low maintenance costs.
The VISATRON® Oil Mist Detection System is
designed to last for the entire engine lifetime.
Surfaces that can generate intensive oil mist in
addition to the crankshaft bearing system include:
Pistons in cylinder liners
Crankshaft bearings such as main
bearings and big-end bearings
Camshafts, their bearings, and cams
Timing gear shafts and their bearings
Gear boxes with their bearings, and in some cases pumps
Guide blocks and paths in crosshead engines
Oil mist in these sliding surfaces can only be monitored by an oil mist detection system, and therefore in the case of an
overheating phenomenon starting in one of them, or a possible piston seizure occurring, an oil mist detection system
should be employed.
Class Approval
SOLAS requirement for oil mist detectors – Engines of 2,250 kW and above or having cylinders of more than 300mm bore
shall be provided with crankcase oil mist detectors, engine bearing temperature monitors or equivalent devices. As per
IACS M10.8 oil mist detection arrangements (or engine bearing temperature monitors or equivalent devices) are required:
For alarm and slow down purposes for low-speed diesel engines of 2,250 kW and above or having cylinders of m0re than
300mm bore for alarm and automatic shutoff purposes for medium- and high-speed diesel engines of 2,250 kW and above
or having cylinders of more than 300mm bore. SCHALLER AUTOMATION developed the VISATRON® oil mist detectors
to meet the IACS UR M10.
Our oil mist detectors are:
Type approved for closed areas
Designed for installation on combustion engines
Approved for environmental category D
Conform to IACS UR M67
