EXPLOSION ISOLATION SYSTEM – HRD BARRIER

HRD barriers are characterized by extremely fast discharge of an extinguishing agent into pipes
connecting pieces of technological equipment. Explosion pressure propagates through the pipes
first during an explosion followed by a flame front. Both of these quantity can be detected by
special detectors – both optical and pressure that were developed for the purpose.

ADVANTAGES:
HRD barrier is suitable for prevention • High reaction speed of the system from
of explosion propagation in pipes of detection to extinguishing
filters, reservoirs, mills, crushers, • Independent archiving of detector data
separators, cyclone dryers and • Variability of detector, control unit and
container unit use
other devices with danger of dust • High quality components
explosions. • Customization according to customer
quality wishes
• Use in inside and outside areas
• High reliability of the system

DIAGRAM OF HRD BARRIER INSTALATION ON A PIPE
The detectors relate a signal to a control
unit that activates HRD container units. The
bottles are equipped by fast-opening valves
capable to immediately release extinguishing
agent to the protected space, and create very
effective extinguishing agent barrier.
