Laminar flow in ducts (1) creates a hot air envelop
(800oF) around the spark/ember (1400oF)
and feeds oxygen to the spark, (2) the spark is
buoyed up and floats along in the gas stream for 100
feet or more.
The QUENCHER spark arrestor creates extreme
turbulence and breaks apart the envelop, strips the
oxygen (fuel) away from the burning spark,
extinguishing and cooling it. The temperature of the
spark is now too low to cause an ignition and fires. The
cooled sparks are safely carried along the gas
stream to the
dust collector.
Simple
and practical (for fire protection)
Inline device that is simply inserted in the
existing or new ductwork of a dust collection system.
No collection drum or device required.
This is a static device, with no moving parts
or electrical connections.
No
water or chemical retardants are injected.
No
calibration or adjustments needed.
No
factory trained personnel needed to install.
Your own people can do it.
CAUTION: Air mixing or air blending devices,
being marketed as
spark arresters/coolers, do not create enough turbulence and
have gaps in the cells permitting sparks to slip through.
Beware of Imitators!
Air mixing/blending devices that are applied to and/or passed off as
spark arrestors or spark cooling devices; they are not 100%
effective. QUENCHERTM
is the first and only
in-line device designed specifically as a spark arrestor,
first and foremost. Its secondary function is as an air
mixer.
To help reduce the
issues associated with dust accumulations, an
optional BOOSTER – DUCT CLEANER device can be
installed in front of the Quencher. This device can
be actuated manually or automatically.
For more information on this
device, ask for our technical bulletin, "Auto
Booster – Duct Cleaner”.
If we mix two
gas streams flowing through well designed
transitions that maintain laminar flow, the result
is that the gas streams will continue in the duct
with little or no mixing of the combined gas
streams.
The
QUENCHER
TM design is
such that the whole cross section of the duct
produces an effective mixing.
The QUENCHER TMis the ideal spark arrester and air mixing device to
prevent fires and explosions in dust collector systems. This spark
arrestor is the easiest to install, requires no power to
operate and little or no maintenance.
