The new QMI TRIPLEX™
monitoring system is the practical answer
to meet the need for oil mist monitoring
in areas where only one, two or three
detectors are required.
QMI atmospheric oil mist
systems identify a hazardous build-up
of oil mist in confined zones.
The oil mist concentration
in the atmosphere is instantly reported
back to the monitor to give advance warning
of dangerous conditions in order to prevent
the outbreak of fires.
The detectors incorporate
a small fan to ensure a positive stream
of air through the sensing system and
are sited in the airflow usually over
the equipment being monitored..
Suggested applications
are:
Hydraulic pack locations as recommended
by OCIMF SIRE Programme Ships Inspection
Report 11.25
The QMI TRIPLEX system
is simple to install on
new or existing vessels with the following
advantages:
Fast response
No false alarms
Easy to read
No scanning
All detectors are calibrated and interchangeable
User friendly working
instructions
on the face plate
Detectors can be located
more than 100 metres from the monitor
Minimal maintenance
Avoids major clean
up operations
ATMOSPHERIC OIL MIST
DETECTION
QMI are in the forefront
of atmospheric oil mist detection. The
need for such a monitoring system was
first recognised when the maritime industry
acknowledged that up to 65% of fires at
sea are the result of oil mist leaks from
areas where lubricating, fuel or hydraulic
oils are under pressure causing a fine
mist to collect in the atmosphere and
leading to a fire. The answer is to install
an oil mist detection system that will
detect oil mist as it is being spread
into the atmosphere and alarm long before
it reaches a dangerous level. Sources
of ignition can be many including exhaust
pipes, turbochargers, and non-flameproof
motors and static electricity.
The QMI MULTIPLEX system
was originally developed in the early
eighties to warn of avoidable engine damage
and fires. Our customers asked if the
detector was suitable to measure oil mist
in the atmosphere as the engine crankcase
system was by then recognised for its
immediate response without any false alarms.
This was a sound basis from which to start
and the reliability of the proven system
gives the operator confidence to act when
an alarm is raised.
The marine industry trialed
a new detector designed to measure oil
mist in the atmosphere and Seatrade gave
the design the prestigious award of a
highly commended contribution to Safety
at Sea in 1997. The design has since been
modified to facilitate maintenance and
to operate in the extreme working environments
found at sea.
