Chemical explosion propagation protection system
- ANTIDET BARRIER
Chemical barrier protection system is also known as HRD - High Rate Discharge - Barrier.
In the case of explosion and it's propagation through the pipeline, it's optical or pressure effects are detected by the sensors and the extinguish agent is sprayed into the pipeline, which will extinguish the flame of the explosion. This is how the explosion propagating through the pipeline is stopped.
System for extinguishing the flame in the pipeline (also known as HRD barrier) consists of optical and/or pressure detector, control unit and action element(s) with the extinguish agent.
System for flame extinguishing manufactured by VST Engineering - ANTIDET BARRIER:
- company's own product
- certification according to ATEX (94/9/EC)
- certification made also according to the latest European Standard EN 14 373 (valid from the mid of 2007)
- high reliability - permanent monitoring of all parameters necessary for system's correct function
- high variability in combination of explosion detectors and action elements
- minimal costs of maintenance and run
- for the opening no explosive or detonator is used (safe manipulation)
- certified with extinguish agent suitable for food and pharmaceutical industry (SBC - sodium bicarbonate) and for metal dusts (Furex)
