An error has occurred.


The HRD (high rate discharge) system detects the inception of explosion inside a piece of equipment and then suppresses it quickly in the protected space. The equipment reaction time counts in milliseconds. The HRD system thus effectively suppresses explosion, limits explosion pressure inside equipment under its pressure resistance and thus prevents its destruction.


When explosion occurs, detectors will start signaling alarm within milliseconds, the system will open HRD valves and activate HRD bottles with extinguishing material. Extinguishing agent pressure will extend special telescopic nozzles that will provide effective spread of the extinguishing agent into the whole protected system. The activation takes place very quickly. The explosion pressure is, thanks to the HRD system, under control and its undesired effects are minimized.



Pressure detectors recognize incipient explosion in time. They will pass this information to the control unit extremely quickly. Their advantage is a short reaction time (in milliseconds) and variability of use.


Simple or multiple zone control unit evaluates and archives detector information, activates extinguishing bottles, monitors circuits for connection of other devices, provide data to superior systems and serves as a user interface to the operators.


Special HRD vessels equipped by fast- opening valves and other accessories contain extinguishing agent under stable pressure. When an explosion is detected, they provide immediate and effective introduction of the extinguishing agent into the protected equipment. Variability of bottle sizes (5, 8, 20 or 50 liters), quick and fast explosion suppression are the advantages. Easy manipulation and simple maintenance are a bonus for the customer.
