Gielle HFC-23™ is a
specialist suppression agent with characteristics not unlike
those of Halon 1301. Browse our Web Library for more
information on this interesting agent - it may be the one you
have been looking for.
Gielle HFC-23™ is the extinguishing agent for specialist
applications ranging from offshore oil platforms and
industrial storage areas to locomotives and anechoic chambers.
Gielle HFC-23™ is Trifluoroethane - a high-pressure
clean agent which contains no Bromine or Chlorine, hence its
ODP of zero. Fires are quickly and efficiently suppressed with
Gielle HFC-23™ by the process of physiochemical thermal
transfer, the presence of the Gielle HFC-23™ molecule at
the flame front absorbing heat from a fire as a sponge absorbs
liquid.
Gielle HFC-23™ is safe to personnel - no exposure
restrictions have been set for its use in occupied areas up to
the NOAEL of 30%. Gielle HFC-23™ is kind to the
environment - it does not deplete stratospheric ozone.
Since the phase-out of Halon 1301, a gap has existed in
certain applications for which Halon was ideally suited. These
applications involved areas greater in height than three
metres, those where high concentrations were required in
occupied areas and those where agent cylinder storage areas
could be subject to extremely low temperatures - the
"High, High, Low aspect of Gielle HFC-23™ satisfies
the requirements for these specialist applications;
High nozzle
height applications
The high pressure nature of
Gielle HFC-23™ gives it an advantage in UL approval
height testing. Gielle HFC-23™ nozzles have been tested
to a height of 7.6 metres, which is greater than any currently
listed clean agent system and close to the maximum for Halon
1301 of 9 metres.
High concentration inerting applications: With a NOAEL of 30%,
Gielle HFC-23™ will allow for high concentration
application without human exposure restrictions. The most
common of these is inerting applications where, depending on
the fuel to be inerted, Gielle HFC-23™ maybe the only
answer without human exposure limitations.
Low temperature applications: Gielle HFC-23™ is suitable
for use at a minimum storage temperature of -40 degrees C
whilst other agents have limitations in the region of zero
degrees C. Halon 1301 offered -4O degrees C storage and Gielle
HFC-23™ is the only clean agent capable of providing
this low temperature feature.
Gielle offers a complete range of services to support HFC-23™
clean agent systems including system design, installation,
maintenance and 24 hour service
