1. What is ExerTherm?
ExerTherm is a system specifically designed to detect faults
BEFORE they occur in key electrical switchgear and plant (motors,
pumps, gearboxes, bearings etc).
2. How does it work ?
ExerTherm uses patented small, plastic bodied, non-contact
IR sensors, which require no power. These can be placed inside
the switchgear enclosures, and directly thermally monitor
any component 24 hours a day, feeding data back to a PC giving
on-going trend analysis.
3. Is ExerTherm similar to thermal
imaging ? Both use non-contact infrared to measure
the temperature of the target, but that’s where the similarity
ends. Thermal imaging is only periodic not continuous and
has to be done from outside the enclosure, no IR device can
see through a solid object so a thermal imaging camera only
measures the temperature of the panel surface not the components.
ExerTherm provides continuous 24/7 protection and sensors
can be placed inside the enclosure.
4. Don’t thermal windows overcome
these problems ? They improve the view from camera
to target, but still don’t overcome how to inspect targets
which cannot be viewed directly. The inspection still remains
only periodic, with ExerTherm the sensors are fitted inside
the enclosure exactly where you need them, nothing is missed
and they monitor 24 hours a day.
5. How do I know that a component
is likely to fail ? Automatic data logging provides
trend reports and instant on-screen trend graphs. Each sensor
also has 2 settable alarm levels (warning and alarm), which
trigger in the event that the temperature of the component
exceeds pre-set limits. With the problem component identified
you have time to plan a quick shut down to replace the part.
6. How reliable are these sensors?
They are the result of a long-standing co-operation between
QHi Infrared and Exergen Corp, one of the world’s leading
manufacturers of non contact infrared sensors for industry.
Specified throughout the world they provide true “fit & forget”
reliability, having a MTBF of 1000YR+
7. How many sensors can I have
on a system ? The standard system can have up to
348 sensors, whilst the XL system can accommodate several
thousand.
8. Where should ExerTherm be
used ? It was originally designed to monitor key
components within electrical switchgear enclosures, (i.e ACB’s,
switches, busbars etc). However, virtually all key plant can
be continually monitored on the same system, using either
the IR sensors, or by contact or air temperature thermocouples.
Typical key plant would be pumps, motors, bearings, steam
traps air handling systems etc.
9. Can it be retro-fitted to
existing switchgear enclosures ? Yes, and very easily.
It can be designed into new switchgear enclosures, and can
also be subsequently expanded once installed.
10. Can it interface with existing
BMS or EMS ? Yes. It can interface with over 250
systems both easily and inexpensively, even sharing the same
computer if required.
11. Can data be transferred to other
locations ? Yes, with our latest M2M technology we
can transfer data collected via Internet, or utilizing latest
wireless technology.
12. What type of businesses are
most likely to benefit from installing ExerTherm ?
Basically, any business which is power critical, i.e. has
high downtime costs or is safety compromised in event of a
major power failure. Examples include computer data centers,
financial services buildings, telecommunications, media, shipping,
defense / govt establishments, large scale continuous manufacturing,
city metro systems, petro-chemical plants, etc.
